Information on IAPMO Codes and Standards Development 1. Applicable Regulations. The primary rules governing the processing of the Uniform Solar Energy & Hydronics Code and Uniform Swimming Pool, Spa and Hot Tub Code are the IAPMO Regulations Governing Consensus Development. Other applicable rules include Technical Meeting Convention Rules, and Guide for the Conduct of Participants in the IAPMO Codes and Standards Development Process. For copies of these documents, contact the Code Development Department at IAPMO World Headquarters at 4755 E. Philadelphia Street, Ontario, CA 91761-2816 USA, or at 909-472-4100. These documents are also available at the IAPMO website at www.iapmo.org. The following is general information on the IAPMO process. All participants, however, should refer to the actual rules and regulations for a full understanding of this process and for the criteria that govern participation. 2. Technical Committee Report (TCR). The Technical Committee Report is defined as the Report of the Technical Committee, consisting of the Report on Proposals (ROP), as modified by the Report on Comments (ROC), published by the Association. 3. Report on Proposals (ROP). The ROP is defined as “a report to the Association on the actions taken by Technical Committees, accompanied by a ballot statement and one or more proposals on text for a new Document or to amend an existing Document”. The ROP and the ROC together comprise the Technical Committee Report. Anyone who does not pursue an issue, either in person or by designated representative in accordance with Section 7.0 (Public review and Comment of the Regulations Governing Consensus Development), as a proposed amendment of the Report on Proposals will be considered as having their objection resolved. 4. Report on Comments (ROC). The ROC is defined as “a report to the Association on the actions taken by Technical Committees, accompanied by a ballot statement and one or more comments resulting from public review of the Report on Proposals (ROP).” The ROP and the ROC together constitute the Technical Committee Report. Anyone who does not pursue an issue, either in person or by designated representative in accordance with Section 8.0 (Public review and Comment of the Regulations Governing Consensus Development), as a proposed amendment of the Report on Comments will be considered as having their objection resolved. 5. Appeals. Anyone can appeal to the Executive Committee concerning procedural or substantive matters related to the development, content, or issuance of any Document of the Association or on matters within the purview of the authority of the Committee. Such appeals must be in written form and filed with the Secretariat (see 9.0 of the Regulations Governing Consensus Development). Time constraints for filing an appeal must be in accordance with Section 9.0. Objections are deemed to be resolved if not pursued at this level. 6. Document Issuance. The USEHC/USPSHTC Executive Committee is the issuer of the Uniform Solar Energy & Hydronics Code and Uniform Swimming Pool, Spa and Hot Tub Code. The committee acts on the issuance of a Document within sixty days from the date of the recommendation from the ROC Technical Committee Meeting, unless this period is extended by the Executive Committee. To: IAPMO Members and Other Interested Parties Date: February 2014 Enclosed is your 2014 Report on Proposals (ROP). These proposals were presented to the Swimming Pool, Spa & Hot Tub Code Technical Committee who met in Ontario, California on October 28, 2013. Lynne Simnick Recording Secretary IAPMO Executive Committee Arnold Rodio Chairman Swimming Pool, Spa & Hot Tub Code TC Jim Kendzel Chairman Solar Energy & Hydronics Code TC All comments for consideration by the Technical Committee should be submitted to IAPMO by June 20, 2014. On October 28, 2014, the Technical Committee will consider all the comments received in response to the actions contained within the ROP for the Uniform Swimming Pool, Spa & Hot Tub Code (USPSHTC) and will vote on whether to modify any of their previous actions. Following the ROP is a preprint of the USPSHTC, as it would appear in the event that all of the proposals accepted by the USPSHTC Technical Committee in October 2013 are ultimately approved for inclusion in the final version of the 2015 edition of the Uniform Swimming Pool, Spa & Hot Tube Code. This preprint is provided to you as a courtesy. All changes are tentative and subject to revision. This document is not to be considered the final version of the 2015 Uniform Swimming Pool, Spa & Hot Tub Code. Specific authorization from IAPMO is required for replication or quotation.

This document shall be known as the “Uniform Swimming Pool, Spa, and Hot Tub Code,” may be cited as such, and will be referred to herein as “this code.”. 102.4 Additions, Alterations, renovations, or repairs. Additions, alterations, renovations, or repairs to a swimming pool, spa, or hot tub system shall conform to that required for a new system without requiring the existing swimming pool, spa, or hot tub system to comply with the requirements of this code. Additions, alterations, renovations, or repairs shall not cause an existing system to become unsafe, insanitary, or overloaded. Additions, alterations, renovations, or repairs to existing swimming pools, spas, or hot tubs shall comply with the provisions for new construction, unless such deviations are found to be necessary and are first approved by the Authority Having Jurisdiction. 102.7 moved Structures. Parts of the swimming pool, spa, hot tub, or plumbing systems of a building or part thereof that is moved from one foundation to another, or from one location to another, shall be in accordance with the provisions of this code for new installations and completely tested as prescribed elsewhere in this section for new work, except that walls or floors need not be removed during such test where other equivalent means of inspection acceptable to the Authority Having Jurisdiction are provided. 104.3.2 Plan review Fees. Where a plan or other data is required to be submitted by in accordance with Section 104.3.1, a plan review fee shall be paid at the time of submitting plans and specifications for review. The plan review fees for work to install, alter, or repair a swimming pool, spa, hot tub system, or part thereof shall be determined and adopted by this jurisdiction. The plan review fees specified in this subsection are separate fees from the permit fees specified in Section 104.5. Where plans are incomplete or changed so as to require additional review, a fee shall be charged at the rate shown in Table 104.5. 104.3.3 information on Plans and Specifications. Plans and specifications shall be drawn to scale upon substantial paper or cloth and shall indicate the location, nature, and extent of the work proposed and show in detail that it is in accordance with the provisions of this code and relevant laws, ordinances, rules, regulations, and Section 104.3.3.1 through Section 104.3.3.3. The Authority Having Jurisdiction shall have the option to accept plans and specifications electronically, in lieu of on cloth or paper, in whatever format it shall require. 104.4.6 retention of Plans. One set of approved plans, specifications, and computations shall be retained by the Authority Having Jurisdiction until final approval of the work covered therein. One set of approved plans, and specifications, computations, and manufacturer’s installation instructions shall be returned to the applicant, and said set shall be kept on the site of the building or work at times during which the work authorized thereby is in progress. 104.5.1 Work Commencing before Permit issuance. Where work for which a permit is required by this code has been commenced without first obtaining said permit, a special investigation shall be made before a permit shall be is issued for such work. 104.5.2 investigation Fees. An investigation fee, in addition to the permit fee, shall be collected whether or not a permit is then or subsequently issued. The investigation fee shall be equal to the amount of the permit fee that is required by this code if a permit were to be issued. The payment of such investigation fee shall not exempt a person from compliance with other provisions of this code, nor from a penalty prescribed by law. 105.1 General. Structures, materials, equipment, appurtenances, swimming pool, spa, and hot tub systems, and other associated components for which a permit is required by this code shall be inspected by the Authority Having Jurisdiction. 1 No portion of structural components, equipment, swimming pool, spa, and hot tub systems, appurtenances, and other associated components, or portion thereof, shall be covered, concealed, or put into use until inspected and approved as prescribed in this code. Neither the Authority Having Jurisdiction nor the jurisdiction shall be liable for expense entailed in the removal or replacement of material required to permit inspection. Swimming pools, spas, and hot tubs regulated by this code shall not be connected to the water, the energy fuel supply, or the sewer system until authorized by the Authority Having Jurisdiction. 105.2.2 Other inspections. In addition to the inspections required by this code, the Authority Having Jurisdiction shall be permitted to require other inspections of plumbing work to ascertain compliance with the provisions of this code and other laws that are enforced by the Authority Having Jurisdiction. 105.2.3 inspection requests. It shall be the duty of the person doing the work authorized by a permit to notify the Authority Having Jurisdiction that such work is ready for inspection. The Authority Having Jurisdiction shall be permitted to require that a request for inspection be filed not less than 1 working day before such inspection is desired. Such request shall be permitted to be made in writing or by telephone, at the option of the Authority Having Jurisdiction. It shall be the duty of the person requesting inspections in accordance with this code to provide access to and means for inspection of such work. 105.2.6 reinspections. A reinspection fee shall be permitted to be assessed for each inspection or reinspection where such portion of work for which inspection is called is not complete or where required corrections have not been made. This provision is shall not to be interpreted as requiring reinspection fees the first time a job is rejected for failure to be in accordance with the requirements of this code, but as controlling the practice of calling for inspections before the job is ready for inspection or reinspection. Reinspection fees shall be permitted to be assessed where the approved plans are not readily available to the inspector, for failure to provide access on the date for which the inspection is requested, or for deviating from plans requiring the approval of the Authority Having Jurisdiction. To obtain reinspection, the applicant shall file an application therefore in writing upon a form furnished for that purpose and pay the reinspection fee in accordance with Table 104.5. In instances where reinspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid. 106.2 Notice of Correction or Violation. Notices of correction or violation shall be written by the Authority Having Jurisdiction and shall be permitted to be posted at the site of the work, mailed, or delivered to the permittee or his their authorized representative. Refusal, failure, or neglect to comply with such notice or order within 10 days of receipt thereof, shall be considered a violation of this code and shall be subject to the penalties set forth by the governing laws of the jurisdiction. SubStANtiAtiON: 1. The following revisions throughout Chapter 1 correlate with similar revisions made to the 2015 UPC and 2015 UMC. 2. In Section 102.7, text has been added to clarify that a system within a moved building has to comply with all of the applicable provisions of the code for new installations, and not just the testing provisions. 3. In Section 104.3.3, text has been added to clarify that it is important for the AHJ to be able to work with other departments within the jurisdiction. 4. In Section 104.4.6, text has been added to clarify that a set approved construction documents includes plans, specifications, computations, and manufacturer’s installation instructions; and such documents should be kept on the building site until the project is completed. 5. In Section 105.2.2, the text “of plumbing work” is being proposed for deletion as there may be other types of inspections that need to be conducted that do not pertain to the plumbing components of a swimming pool, spa, or hot tub (ex: structural, mechanical, etc.). 6. The remaining proposed changes are being done in accordance with IAPMO’s Manual of Style.

Plans, engineering calculations, diagrams, and other data shall be submitted in one or more sets with each application for a permit. The Authority Having Jurisdiction shall be permitted to require plans, computations, and specifications to be prepared by, and the plumbing designed by, an engineer, an architect, or both who shall be licensed by the state to practice as such a registered design professional. Plans and specifications for indoor installations of public or private swimming pool, spa, hot tub, bathing, aquatic play, or wading facilities shall be submitted to the Authority Having Jurisdiction for approval prior to commencement of work, piping, equipment, or combination thereof. Construction shall be equal to the types prescribed in the installation requirements of the plumbing code. Exception: The Authority Having Jurisdiction shall be permitted to waive the submission of plans, calculations, or other data where the Authority Having Jurisdiction finds that the nature of the work applied for is such that reviewing of plans is not necessary to obtain compliance within the code. 220.0 registered Design Professional. An individual who is registered or licensed by the laws of the state to perform such design work in the jurisdiction. SubStANtiAtiON: 1. The following revision to Section 104.3.1, and the new definition for “registered design professional” correlates with similar proposed changes made to the 2015 UPC and 2015 UMC. 2. This proposed change is to add a definition and correlate the industry recognized term “registered design professional” with the related terms currently used in the USPSHTC. The term “registered design professional” is the accepted term for an architect, engineer, or other professional who is licensed and certified by a state to practice their respective design profession. This is also the term used in construction and safety codes adopted by many state and local jurisdictions throughout the U.S. COmmittee ACtiON: Accept as Submitted tOtAL eLiGibLe tO VOte: 12 VOtiNG reSuLtS: AFFIRMATIVE: 12 3 USPSHTC 2015 – (104.3.2, 104.5, 105.2.6, Table 104.5): Submitter: Tim Ross Ross Distributing, Inc.

A reinspection fee shall be permitted to be assessed for each inspection or reinspection where such portion of work for which inspection is called is not complete or where required corrections have not been made. This provision is not to be interpreted as requiring reinspection fees the first time a job is rejected for failure to be in accordance with the requirements of this code, but as controlling the practice of calling for inspections before the job is ready for inspection or reinspection. Reinspection fees shall be permitted to be assessed where the approved plans are not readily available to the inspector, for failure to provide access on the date for which the inspection is requested, or for deviating from plans requiring the approval of the Authority Having Jurisdiction. To obtain reinspection, the applicant shall file an application therefore in writing upon a form furnished for that purpose and pay the reinspection fee in accordance with Table 104.5 Section 104.5. In instances where reinspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid. tAbLe 104.5 SWimmiNG POOL, SPA, AND HOt tub Permit FeeS SubStANtiAtiON: Jurisdictions typically have their own permit fee schedule for swimming pools, spas, and hot tubs. Therefore, such a fee schedule should be referenced in the code, instead of Table 104.5, which is applicable to the construction and installation practices of a jurisdiction. Furthermore, the proposed language is consistent with provisions found in other applicable codes and standards. COmmittee ACtiON: Reject COmmittee StAtemeNt: The fee schedule should not be deleted as it can be used, as a baseline, by jurisdictions that do not have an established fee schedule. tOtAL eLiGibLe tO VOte: 12 VOtiNG reSuLtS: AFFIRMATIVE: 12 4 USPSHTC 2015 – (Chapter 2): Submitter: Arnold Rodio Pace Setter Plumbing, Corp Item # 004 reCOmmeNDAtiON: Add new text as follows: 203.0 Accepted engineering Practice.

SubStANtiAtiON: Section 1417 of the Safe Drinking Water Act (SDWA) was amended by Senate Bill 3874 – 2010. This bill changed the definition of “lead free” in the Safe Drinking Water Act from not more than 8 percent lead to not more than a weighted average of 0.25 percent. The 0.2 percent requirement for solder and flux is not new to the SDWA, and is in fact already addressed in Section 304.3.4 of the USPSHTC. It is being repeated in Section 303.10 to ensure that manufacturers, installers, and AHJ’s are aware of the requirement by locating it in the same section with the other provisions of the SDWA. Senate Bill 3874 also added exceptions to Section 1417 of the SDWA to clarify which products do not need to meet the lead content requirements of the SDWA.

(renumber remaining sections‚) 203.0 Aquatic Facility. A public facility that contains one or more aquatic venues and support infrastructure under a single management structure. Aquatic Venue. An artificially constructed or modified natural structure where the general public is exposed to water intended for recreational or therapeutic purposes. 218.0 Purging. The process of introducing outdoor air, and exhausting an equal volume of inside air, to reduce the effects on indoor air quality caused by chloramines and other air contaminants. SubStANtiAtiON: The proposed code language is based in part on the work of the Ventilation & Air Quality Technical Committee of the Model Aquatic Health Code (MAHC) (Sections 4.6.2, 4.6.2.2.5, 4.6.2.3, 4.6.2.4, and 4.6.2.5 ). It is critical for a code to define ventilation systems and establish parameters for air quality that reduces the risk of potential health effects such as ocular and respiratory distress. With the recent increase in large indoor water parks, which have high bather loads and a contamination burden unseen before, indoor air quality is an increasingly important health concern. The purpose of the ventilation system is to assure the health and comfort of the users of the facility by bringing in fresh air from the outside, and reducing the effects of disinfection byproducts (DBPs) (ex: trichloramine), bather wastes (ex: feces, urine, sweat, skin cells), and the outside environment (ex: dirt) on indoor air quality. Table 417.1 is mostly consistent with values found in ASHRAE 62.1, except for the Rp and density factors provided for the different types of aquatic venues and deck. This is because ASHRAE 62.1 only accounts for the building space of an aquatic facility without taking into account the effect that the number of occupants has on indoor air quality. Therefore, the rationale used for developing Table 417.1 is based on bather load density, aquatic venue type, deck areas, and spectator areas as follows: Flat Water Contributes to poor air quality only when bathers are splashing, therefore releasing DBPs into the air. These aquatic venues are generally used for swimming. The density was established at 20 square feet per person. This represents an average horizontal swimmer occupying a 5 foot by 4 foot area. Assuming a person is swimming horizontally; a full body length is an average 5 feet with a 5 feet span to equal 25 square feet. There was a need to account for higher density in shallow areas where users wade vertically versus swim horizontally. The middle ground was decided to be 20 square feet. • 38 - • • • • Agitated Water These are aquatic venues that contain aquatic features (ex: slides) that disturb the water surface. They contribute to poor air quality any time the aquatic features are operating. This constant introduction of DBPs into the air requires more fresh air for these types of aquatic venues. These aquatic venues are generally are for wading and enjoyment without swimming. The density was established at 15 square feet per person. This represents an average vertical user occupying a 5 foot by 3 foot area. Hot Water These aquatic venues require more chemicals and release more DBPs due to increased chemical demand, increased introduction of bather waste, and increased evaporation, which deposits more DBPs into the air per square foot than any other aquatic venue. This type of aquatic venue requires the most outdoor air. These aquatic venues generally are for lounging such as spas, hot tubs, etc. The density was established at 10 square feet per person. This represents an average user sitting in a 3 foot by 3 foot area. Deck Areas One can assume 50 square feet per person. Adding seating and tables, which separates groups, the square footage allows for less density. Spectator Areas For spectator areas, the committee used 6.6 square feet per person for seating that is based on ASHRAE 62.1. This seating is generally well above the water level. - Equation 417.1, which is based on ASHRAE 62.1, is used to determine the minimum outdoor air requirements, and then adds additional fresh air for each aquatic venue type, deck space, and spectator area which is permitted by ASHRAE 62.1. For indoor aquatic facilities with more than one type of aquatic venue, the total outdoor air required is calculated by adding together the outdoor air required to address the contaminants of each individual aquatic venue (flat water, agitated water, and hot water), deck area, and/or spectator area. In Section 417.2, it is important for the ventilation system to maintain the surface temperature of exterior windows and skylights to reduce surface condensation and mold growth; these values are based on the ASHRAE Handbook. The ventilation system should be capable of purging the indoor air of an aquatic facility in times when an aquatic venue may need a large dose of chemicals to bring unbalanced water chemistry under control or there is an accidental chemical spill. In Section 417.3, according to the ASHRAE Handbook, a natatorium should be maintained at 0.05 – 0.15 inch water column negative pressure relative to adjacent areas to prevent the migration of chloramines into other areas of an aquatic facility where aquatic venues are not located. For Section 417.4, maintaining a relative humidity of not more than 65% in an indoor aquatic facility environment is important for a variety of reasons. Research has shown elevated relative humidity levels often coincide with mold growth, damage to building structures, bather discomfort, and inadequate ventilation. The 65% threshold is based on ASHRAE 62.1. It should be recognized that air temperature is largely a comfort factor, but high air temperatures do affect air circulation and could lead to heat exhaustion in users. The air temperature ranges are based on the ASHRAE Handbook. For Section 417.5, ventilation system equipment should be located to prevent unauthorized access that could jeopardize public health and safety. Furthermore, in the case that equipment needs to be replaced, a permanent plate or label should be located on the equipment to ensure that the amount of outdoor air provided by such equipment is considered in order to maintain the overall design of the ventilation system.

The symbol and lettering shall be not less than 4 inches (102 mm) in height; shall contrast with the background it is placed; shall be weather-resistant; and shall be slip-resistant where located on the deck. SubStANtiAtiON: The proposed code language is based in part on the work of the Facility Design and Construction Technical Committee of the Model Aquatic Health Code (MAHC) (Section 4.5.19.4). That vast majority of industry standards allow for diving into a pool with a water depth greater than 5 feet. According to a study conducted by the American Red Cross, 99% of neck injuries occur in water depths less than or equal to 5 feet. The size and type of symbol or lettering correlates with the provisions already stated in Section 403.3 of the USPSHTC.

A piece of equipment or appurtenance that is slip-resistant and is intended to be used for an individual to grasp when in distress, steady an individual as they enter or exit, or situates oneself within, a swimming pool, spa, or a hot tub. SubStANtiAtiON: The sides of a swimming pool are the necessary point of safety, and therefore handholds are necessary in order for a bather to grasp when in distress. Just like wading pools, shallow ends of swimming pools where the water depth is less than 24 inches should not be required to have handholds. Handholds are not necessary for where an underwater seat or bench is installed since a bather can just sit, or for wading pools since the water depth is not greater than 18 inches. This proposal will address a current gap in coverage within the code that is consistent with other industry standards and codes. The 2 inch maximum size for the handholds is based on the hand size of an average adult that is consistent with industry standards and practices. Handholds for spas and hot tubs should be located not more than 6 inches above the water surface so that a child can easily access. In Section 405.9.1, ledges are the same thing as coping, and therefore redundant. It is very common for the lip of a gutter system to be designed for use as a handhold in a pool or spa, and therefore should be referenced in the code. COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 403.5 Handholds. Handholds shall be provided for swimming pools where the water depth exceeds 24 inches (610 mm).

Underwater benches and seats shall not be located in water depths that exceed 5 feet (1524 mm). The submerged depth of a bench or seat shall not exceed 24 inches (610 mm) measured from the water line. 418.2 underwater Ledges. For public swimming pools, underwater ledges shall be constructed of slip-resistant materials; shall be outlined with a color contrasting stripe or other permanent marking of not less than 1 inch (25.4 mm) or more than 2 inches (51 mm) in width; and have a horizontal tread depth of not more than 4 inches (102 mm). Underwater ledges shall be installed in water depths of not less than 5 feet (1524 mm). 223.0 underwater Ledge. A continuous step that is recessed or protrudes from a pool wall, and allows a swimmer to rest while standing without treading water. Also known as a toe ledge. SubStANtiAtiON: The proposed code language is based in part on the work of the Facility Design and Construction Technical Committee of the Model Aquatic Health Code (MAHC) (Sections 4.5.16 & 4.5.17). It is important where underwater benches or seats are present that public health and safety is safeguarded. This is achieved by providing a slip-resistant surface, and markings that indicate where the bench or seat is located within the pool from the deck. Additionally, the location of the bench or seat shall be such that a 6 foot adult can rest their feet on the pool floor while sitting. Furthermore, the depth of the bench or seat shall be such that a bather can sit with adequate clearance to avoid water from entering the mouth, nose, or eyes. An underwater ledge, just like an underwater bench or seat, should be constructed and located to safeguard public health and safety. This is achieved by providing a slip-resistant surface; markings that indicate where the ledge is located within the pool from the deck; and a sufficient tread depth for standing. An underwater ledge is intended for a bather to rest, without treading water, in water depths that exceed 5 feet. If located in more shallow waters it could easily be a safety hazard where children could become trapped. COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 418.0 underwater benches, Seats, and Ledges. 418.1 underwater benches and Seats. For public swimming pools, underwater benches or seats, where installed, shall be constructed of slip-resistant materials, and shall be outlined with a color contrasting stripe or other permanent marking of not less than 1 inch (25.4 mm) or more than 2 inches (51 mm) in width. Underwater benches and seats shall not be located in water depths that exceed 5 feet (1524 mm).

Artificial lighting shall be provided at public aquatic venues used at night or at public aquatic venues that do not provide, while in use, natural lighting at levels that are in accordance with Section 418.2. Lighting shall illuminate all parts of the aquatic venue including water surface area, main drains, depth markings, signage, entrances, safety equipment, decks, and walkways in accordance with the Authority Having Jurisdiction. Artificial lighting systems shall be installed in accordance with the manufacturer’s installation instructions and NFPA 70. 418.2 Lighting Levels. Lighting levels for the water surface and deck of an aquatic venue shall be not less than the following: (1) Indoor water surface - 30 horizontal footcandles (323 lx). (2) Outdoor water surface - 10 horizontal footcandles (108 lx). (3) Deck - 10 horizontal footcandles (108 lx). 418.3 underwater Lighting. Underwater lighting shall be provided for an aquatic venue at not less than 6 initial rated lumens per square foot (65 lx) of water surface area except where surface lighting levels are not less than15 horizontal footcandles (161 lx) for all portions of the aquatic venue. Underwater lighting shall be grounded in accordance with Section 904.2. 418.4 emergency Lighting. Emergency egress lighting shall be provided in accordance with the building code, but not less than 0.5 footcandles (5.4 lx). 418.5 Glare. Windows, skylights, and overhead lighting shall be located to avoid glare on the water surface area of an aquatic venue in accordance with the Authority Having Jurisdiction. SubStANtiAtiON: The proposed code language is based in part on the work of the Facility Design and Construction Technical Committee of the Model Aquatic Health Code (MAHC) (Section 4.6.1). This code proposal addresses a gap in coverage within the USPSHTC, and provides minimum light levels for aquatic venues that are based on the Illuminating Engineering Society of North America (IESNA) standard, RP-6-88 (Recommended Practice for Sports and Recreational Area Lighting). It is important for minimum lighting levels (whether artificial or natural) to be maintained for an aquatic venue while in use in order to identify, below the water surface, bathers that are in distress or objects that could pose a danger. It should be noted that both artificial and natural light are measured in footcandles (lux), and therefore natural lighting levels can be measured in accordance with Section 418.2. It is critical that NFPA 70 is referenced as it provides safety provisions pertaining to the location, type, and installation of lighting systems. The building code provides provisions for emergency egress lighting that is critical for safeguarding public health and safety, and therefore such reference should be made in the code. Windows, skylight, and overhead lighting should be located to avoid glare on the water surface that could hinder one from identifying a bather in distress or a potential safety hazard. The MAHC defines an “aquatic venue” as, “An artificially constructed or modified natural structure where the general public is exposed to water intended for recreational or therapeutic purposes.” This would include swimming pools, spas, hot tubs, water slides, catch pools, wave pools, leisure rivers, etc. 58 COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 418.2 Lighting Levels. Lighting levels for the water surface and deck of an aquatic venue shall be not less than the following: (1) Indoor water surface – 30 60 horizontal footcandles (323 646 lx). (2) Outdoor water surface - 10 horizontal footcandles (108 lx). (3) Deck - 10 horizontal footcandles (108 lx). COmmittee StAtemeNt: The TC believes that the lighting levels are too low. Increasing the lighting levels for indoor water surfaces to 60 horizontal footcandles is a good start, but the TC intends on submitting public comments to further address the provisions. tOtAL eLiGibLe tO VOte: 12 VOtiNG reSuLtS: AFFIRMATIVE: 12 COmmeNt ON AFFirmAtiVe: OSiNSKi: I will submit a public comment.

The building envelope of a natatorium shall incorporate an approved vapor retarder that is sealed around doors, windows, and skylights, and installed in accordance with the building code. 418.2 interior Finish. The interior finish of a natatorium shall be designed for an indoor relative humidity of not less than 80 percent. 418.2.1 Doors and Glazing. Doors, windows, and skylights shall be constructed of corrosion- and mold-resistant materials. Doors shall be sealed or gasketed, and equipped with automatic door closers. 418.2.2 Ducts. Ducts located on the inside of a natatorium shall be corrosion-resistant. Ducts shall be insulated on the exterior of the duct with a mold-resistant material where the surface temperature of the duct is capable of being less than the airstream temperature within the duct. 418.3 Spectator Areas. A spectator area shall be separated from an aquatic venue by a deck of not less than 8 feet (2438 mm) wide. An approved barrier installed in accordance with Section 903.0, or a demarcation line that is permanently marked on the deck, shall separate the areas of the deck intended for bather and spectator use. SubStANtiAtiON: The proposed code language is based in part on the work of the Facility Design and Construction Technical Committee of the Model Aquatic Health Code (MAHC) (Sections 4.2.2, 4.6.7, and 4.9.1.8.3). Special care should be used in the construction of natatoriums to prevent the movement of moisture into building surfaces that can result in damage to the building structure. Therefore, an approved vapor retarder should be installed in accordance with the building code; which is generally installed on the warm side of the dew point temperature in all walls, ceilings, and floors. It is critical for the vapor retarder to be sealed around all doors, windows, and skylights in order to prevent vapor migration that can occur through openings of a building envelope. The interior finish of a natatorium must be resistant to mold growth, which can result in respiratory issues such as asthma for the public, by being approved for a relative humidity of not less than 80 percent. Doors, windows, and skylights should be resistant to both corrosion and mold growth to safeguard public health. Furthermore, doors should be sealed or gasketed, and incorporate an automatic door closer to minimize air leakage. In order to protect both the indoor air quality and the ductwork located inside a natatorium, ducts must be corrosionresistant (ex: galvanized sheet metal, aluminum sheet metal, fabric duct, etc.) to resist damage caused by chemicals off-gassing from the water surface. Furthermore, in order to prevent contaminated indoor air or damage to the ducts, both caused by condensation, the exterior of the ducts needs to be insulated where the conditions of Section 418.2.2 are possible. Spectator areas should be separated from the aquatic venue by either an approved barrier or demarcation line to prevent accidents from occurring. The 8 foot width is consistent with the 4 foot wide minimum deck requirement found in Section 417.0. The MAHC defines an “aquatic venue” as, “An artificially constructed or modified natural structure where the general public is exposed to water intended for recreational or therapeutic purposes.” This would include swimming pools, spas, hot tubs, water slides, catch pools, wave pools, leisure rivers, etc. The Webster Dictionary defines a “natatorium” as, “An indoor swimming pool.” 60 COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 418.2.1 Doors and Glazing. Doors, windows, and skylights shall be constructed of corrosion- and mold-resistant materials. Doors shall be sealed or gasketed, and equipped with automatic self-closing door closers.

The entire design of matched components shall have a capacity to provide a complete turnover of pool water in accordance with local and state codes or regulations, and the manufacturer’s instructions. Minimum turnover time shall be required as follows: (1) Private pools – 12 8 hours or less (2) Public pools – 6 hours or less (3) Wading pools – 2 1 hours or less (4) Private spas and hot tubs – 1 hour or less (5) Public spas and hot tubs – 1⁄2 hour or less (6) Water slides and catch pools – 2 hours (7) Wave pools – 3 hours (8) Leisure rivers – 3 hours (9) Spray grounds – 1⁄2 hour 222.0 turnover time. The time in hours and minutes required for the circulation system to filter and recirculate a volume of water equal to the pool aquatic venue volume. SubStANtiAtiON: In order to recognize that some jurisdictions, states, or equipment manufacturers may have more stringent provisions for turnover rates than the USPSHTC, language should be added to recognize such provisions. The turnover rates for private pools and wading pools have been revised to correlate with current industry standards and practices. The current provisions are outdated, and not based on industry practices. To maintain water quality in aquatic venues such as: water slides and catch pools; wave pools; leisure rivers; and spray grounds, the USPSHTC should provide minimum turnover times for the water. The proposed values are based on other industry standards and codes. The definition for “turnover time” has been revised accordingly. The Model Aquatic Health Code (MAHC) defines an “aquatic venue” as, “An artificially constructed or modified natural structure where the general public is exposed to water intended for recreational or therapeutic purposes.” This would include swimming pools, spas, hot tubs, water slides, catch pools, etc. COmmittee ACtiON: Accept as Submitted tOtAL eLiGibLe tO VOte: 12 VOtiNG reSuLtS: AFFIRMATIVE: 12 64 USPSHTC 2015 – (504.5, 508.2, 508.3, 508.5.1, 605.0, 605.1): Submitter: Richard Martin NSF International Item # 053 reCOmmeNDAtiON: Revise text as follows: 504.5 multiport Valves.

(renumber remaining sections) SubStANtiAtiON: NSF 50 is the appropriate reference standard for multiport valves, surface skimmers, pumps, and strainers used for public and private swimming pools, spas, and hot tubs. NSF 50 is already referenced in Table 1001.1. In Section 508.3, the ratio of skimmers to the water surface area of private pools, public/private spas, and public/private hot tubs has been revised in accordance with NSF 50 (Annex J). Furthermore, the text “strict” is being deleted as it adds nothing to the application or enforcement of the code text. In Sections 504.5, 508.2, 508.3, and 508.5.1, the text “listed” is not needed as the requirement for devices to be listed and labeled is already addressed in Section 302.1.

Water supply inlets to swimming pools, where protected by an approved vacuum breaker, shall have such device installed on the discharge side of the last valves with the critical level not less than 6 inches (152 mm) above the overflow rim of such equipment. Water supply inlets not protected by vacuum breakers shall be installed not less than two pipe diameters, but in no case less than 1 inch (25.4 mm) above the overflow rim of such swimming pool. No over-the-rim fill spout shall be installed unless it is located under a diving board or is guarded. 505.2 backflow Protection. Potable water supply to swimming pools, spas, or hot tubs shall be protected by an airgap or a reduced pressure principle backflow preventer in accordance with the following: (1) The unit is equipped with a submerged fill line. (2) The potable water supply is directly connected to the unit circulation system. Water supply inlets to swimming pools, spas, or hot tubs shall be protected by one of the following means: (1) An approved air gap. (2) A vacuum breaker installed on the discharge side of the last valve with the critical level not less than 6 inches (152 mm) or in accordance with its listing. (3) A backflow preventer suitable for the contamination or pollution, installed in accordance with the manufacturer’s installation instructions and the plumbing code. SubStANtiAtiON: The proposed revisions will correlate the USPSHTC with the UPC. Furthermore, the proposed text not only recognizes approved air gaps and vacuum breakers as currently stated in the USPSHTC, but recognizes other types of listed backflow preventers that can be used based on the hazard. For example, if a water hose is used to fill a pool then it must be protected with a hose bibb vacuum breaker installed on the faucet in accordance with the manufacturer’s installation instructions and the plumbing code. Per the plumbing code, a hose bibb vacuum breaker would need to comply with ASSE 1019, and a shutoff valve cannot be located downstream of the device.

Filters and filter media shall be installed in accordance with the manufacturer’s installation instructions and shall comply with NSF 50. 506.1 506.2 rapid Sand Filters. Rapid sand filters, having shall have a flow rate of up not to exceed 5 gallons per minute (gpm) per square foot (204 L/m/m2) for private applications and 3 gpm per square foot (122 L/m/m2) for public applications shall be constructed in accordance with approved standards. The circulation system and backwash piping shall be provided for backwashing of sand filter and backwash flow rates of not less than 12 15 gpm per square foot (489 610 L/m/m2). 506.2 506.3 High-rate Sand Filters. High rate sand filters, having shall have a flow rate of up not to exceed 20 gpm per square foot (815 L/m/m2) shall be of an approved type. The circulation system and backwash piping shall be provided for backwashing of sand filter and backwash flow rates of not less than 12 15 gpm per square foot (489 610 L/m/m2). 506.3 506.4 Diatomite type Filters. Diatomite type filters shall be designed for operation under pressure or vacuum. The design capacity flow rate shall not exceed 2.5 gpm per square foot (102 L/m/m2) for private applications and 2 gpm per square foot (81 L/m/m2) for public applications of effective filter area. Provision shall be provided to introduce filter aid into pressure filters through the skimmer or precoat pot. 506.4 506.5 Cartridge Filters. Cartridge filters shall be constructed in accordance with approved standards. Such filters shall be designed for pressure or vacuum applications. The designed flow rate for surface-type cartridge filters shall not exceed 1 gpm per square foot (41 L/m/m2) for private use applications or and 0.375 gpm per square foot (15 L/m/m2) for public use applications. The designed flow rate for depth-type cartridge filters shall not exceed 8 gpm per square foot (325 L/m/m2) for private applications and 3 gpm per square foot (122 L/m/m2) for public applications. 506.5 506.6 Operating instructions. (remaining text unchanged) 506.6 506.7 Pressure Filter System. (remaining text unchanged) SubStANtiAtiON: NSF 50 is the appropriate reference standard for all types of filters and filter media used for public and private aquatic venues and facilities. NSF 50 is already referenced in Table 1001.1. In Section 506.2 (Rapid Sand Filters) and Section 506.3 (High-Rate Sand Filters), the values are based on the maximum flow rate, and therefore the language should be revised accordingly. The text, “shall be constructed in accordance with approved standards,” is no longer needed with Section 506.1 (General) indicating that all filters shall comply with NSF 50. Finally, the minimum design backwash flow rate for sand filters is 15 gpm per square foot in accordance with NSF 50. This is important to control the total dissolved solids that can have a negative impact on free chlorine levels, and therefore resulting in the formation of chloramines. In Section 506.4 (Diatomite Type Filters), the current values are for public swimming pools, spas, and hot tubs only. For private applications, 2.5 gpm per square foot is the maximum flow rate in accordance with NSF 50, and therefore should be added. In Section 506.5 (Cartridge Filters), the current values are for surface-type cartridge filters. Depth-type cartridge filters are the other type recognized by NSF 50, and should be addressed within this section of code as well. The additional revisions provide consistency throughout the entire Section 506.0 (ex: adding “rate” after “flow”, replacing “use” with “applications”, etc.) 68 COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 506.1 General. Filters and filter media shall be installed in accordance with the manufacturer’s installation instructions and shall comply with NSF 50. The maximum design flow rate for filter operation, with alternate media, shall comply with Section 506.2 through Section 506.5, or the filter media manufacturer’s instructions. 506.3 High-rate Sand Filters. High-rate sand filters shall have a flow rate not to exceed 20 gpm per square foot (815 L/m/m2) for private applications and 15 gpm per square foot (610 L/m/m2) for public applications, or the filter media manufacturer’s instructions. The circulation system and backwash piping shall be provided for backwashing of sand filter and backwash flow rates of not less than 15 gpm per square foot (610 L/m/m2). COmmittee StAtemeNt: The modification clarifies that the filter media manufacturer may have more stringent requirements than the code, and therefore should be followed. Furthermore, Section 506.3 has been revised to clarify the flow rates for high-rate sand filters for both private and public applications. tOtAL eLiGibLe tO VOte: 12 VOtiNG reSuLtS: AFFIRMATIVE: 12 COmmeNt ON AFFirmAtiVe: DiNGmAN: We agree with the concept of this proposal.

Chemical feed equipment shall be provided with an automatic controller to power on and off the equipment. Chemical controllers shall comply with NSF 50, and be installed in accordance with the manufacturer’s installation instructions. 507.1.4 Ventilation. A separate ventilation system shall be provided for each enclosed room or space where chemical feed equipment is located at not less than 60 air changes per hour. The exhaust intake of the ventilation system shall be taken within 6 inches (152 mm) of the floor, and located on the opposite side of the room or space from the outdoor air intake. Exhaust air shall be discharged above grade level to the outdoors, and shall discharge not less than 10 feet (3048 mm) from an operable opening or adjacent building. Outdoor air intake shall be provided within 6 inches (152 mm) of the ceiling. 507.2 Gas Chlorinators. 507.9 Chlorinator Design. The chlorinator shall be designed to prevent the backflow of water into the chlorine solution container. 507.3 Ventilation The cChlorine and chlorinating equipment shall be located in a separate well-ventilated room located at or aboveground level. In addition, vents in the ceiling and at floor level that terminate to the outside, shall be provided with a motor-driven exhaust fan, capable of producing not less than 1 air exchange per minute and that draws air from floor level. 507.5 507.2.1 Storage. Chlorine cylinders, including empty cylinders, shall be stored and secured in an upright position. 507.6 507.2.2 Shut Off. A valve wrench shall be installed on the chlorine cylinder valve so the supply can be shut off in the case of an emergency. Valve protection hoods shall be in place except where the cylinder is connected. 507.7 507.2.3 Chlorine Feeding Device Design. The chlorine feeding device shall be designed so that during accidents or interruptions of the chlorinator booster pump leaking chlorine gas shall be conducted to the outdoors. 507.8 507.2.4 type of Feeding Device. The feeding device shall be a solution feed type, capable of delivering chlorine at its maximum rate without releasing chlorine gas to the atmosphere. 507.10 507.2.5 interlocked. 507.2 Protection Against Gas Siphoning Gas-type chlorinators shall have protection against siphoning of gas into the recirculation system. The booster pump shall be interlocked electrically with the recirculation pump to prevent operation of the booster pump where recirculation system is not operating. The recirculating pump and chlorine booster pump motor controls shall be interlocked electrically so that the booster pump shall not operate where the recirculating pump is off, or during the backwash cycle. Connections shall not be made to an external water supply for chlorinator operation. 507.11 507.2.6 Scale. A scale for determining weight of chlorine shall be provided. 70 SubStANtiAtiON: The proposed code language is based in part on the work of the Recirculation Systems and Filtration Technical Committee (Section 4.7.3) and the Facility Design and Construction Technical Committee (Section 4.9.2.5) of the Model Aquatic Health Code (MAHC). Currently the USPSHTC only provides provisions for gas chlorinators; however, there are other types of approved chemical feed equipment (ex: bromine generators, salt electrolytic chlorinators, brine electrolytic chlorinators, etc.) that are used for providing disinfection to aquatic venues. NSF 50 is the appropriate reference standard for chemical feed equipment. NSF 50 is already referenced in Table 1001.1. To reduce the likelihood of disinfectants and acidic chemicals mixing inside of pipes during periods of interruption to recirculation system flow. Means of injection shall not allow backflow into the chemical system from the aquatic venue. Chemical feed equipment should be interlocked electrically to prevent damage to system components due to the equipment operating when there is no water flow. An automatic controller is necessary for maintaining proper disinfectant and pH levels within a public aquatic venue at all times to protect the bathers. To prevent chemical fumes or vapors from migrating into other spaces of an aquatic facility, it is important for a ventilation system to be installed within a chemical feed equipment room or space to maintain proper ventilation. In Section 507.2 (Gas Chlorinators), backflow and ventilation requirements for gas chlorinators are being deleted as such provisions are now addressed in Sections 507.1.1 (Equipment Design) and 507.1.4 (Ventilation). In Section 507.2.5 (Interlocked), the second sentence is being deleted as it is redundant to what is stated in the third sentence. The MAHC defines an “aquatic venue” as, “An artificially constructed or modified natural structure where the general public is exposed to water intended for recreational or therapeutic purposes.” This would include swimming pools, spas, hot tubs, water slides, catch pools, wave pools, leisure rivers, etc. The MAHC defines an “aquatic facility” as, “A public facility that contains one or more aquatic venues and support infrastructure under a single management structure.” COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 507.1.1 equipment Design. Chemical feed equipment shall be capable of withstanding wear without developing leaks. Chemical feed equipment shall be designed to supply disinfectant and pH control chemicals to an aquatic venue at the levels required in accordance with this code. Chemicals shall be introduced into an aquatic venue upstream downstream of the filtration system, and the equipment shall not permit backflow into the chemical feed equipment or components. 507.1.4 Ventilation. A separate ventilation system shall be provided for each enclosed room or space where chemical feed equipment is located at not less than 60 air changes per hour of outdoor air. The exhaust intake of the ventilation system shall be taken within 6 inches (152 mm) of the floor, and located on the opposite side of the room or space from the outdoor air intake. Exhaust air shall be discharged above grade level to the outdoors, and shall discharge not less than 10 feet (3048 mm) from an operable opening or adjacent building. Outdoor air intake shall be provided within 6 inches (152 mm) of the ceiling. 507.2 Gas Chlorinators. Chlorine and chlorinating equipment shall be located in a separate well-ventilated room located at or aboveground level. 71 COmmittee StAtemeNt: The proposed modification to Section 507.1.1 corrects where chemicals are introduced into an aquatic venue in accordance with industry standards. The proposed modification to Section 507.1.4 clarifies to the end user that the “60 air changes per hour” pertains to outdoor air. Finally, in Section 507.2, the language pertaining to the location of chlorine and chlorinating equipment has been retained as it is necessary to safeguard public health and safety. tOtAL eLiGibLe tO VOte: 12 VOtiNG reSuLtS: AFFIRMATIVE: 12 COmmeNt ON AFFirmAtiVe: DiNGmAN: We agree with the concept of this proposal.

Secondary disinfection systems shall comply with NSF 50, and shall be installed in accordance with the manufacturer’s installation instructions. 508.2 Where required. A secondary disinfection system shall be provided for public wading pools, catch pools, spray grounds, and therapy pools. 508.3 System Design. Secondary disinfection systems shall be designed to achieve not less than a 3-log (99.9 percent) reduction in the number of infective cryptosporidium parvum oocysts per pass through the system in accordance with NSF 50. 508.4 Approved Systems. Secondary disinfection shall be provided by an ultraviolet light (UV) system or ozone system. 508.4.1 ultraviolet Light (uV) Systems. Where used, ultraviolet light (UV) systems shall be installed in the recirculation system downstream of the filters and water heating equipment, and upstream of the halogen feed location and pH chemical feed equipment. 508.4.1.1 maintenance. A bypass pipe that is valved on both ends shall be installed on the UV equipment to permit servicing while the aquatic venue is in operation. 508.4.1.2 interlocked. The UV system shall be interlocked electrically with the recirculation pump, and UV equipment shall be provided with calibrated sensors in accordance with the manufacturer’s installation instructions. 508.4.1.3 Strainer. An inline strainer shall be installed downstream of the UV system. 508.4.1.4 Warning. Where the UV system shuts down, an approved visual alarm shall be installed to alert bathers and facility staff. 508.4.2 Ozone Systems. Where used, ozone system side-stream loop shall be installed in the recirculation system downstream of the filters and the water heating equipment, and upstream of the halogen feed location and pH chemical feed equipment. 508.4.2.1 Oxidation reduction Potential. Ozone generating equipment shall be equipped with an approved oxidation reduction potential (ORP) monitor/controller. The ORP of the ozone system shall be not less than 600 mV, and not more than 900 mV where measured after the ozone side-stream remixes into the recirculation system and upstream of the halogen feed location and pH chemical feed equipment. 508.4.2.2 Gas Leak. An ambient ozone gas monitor/controller shall be installed in the equipment room where the ozone system is located. 508.4.2.3 interlocked. The ozone system shall be interlocked electrically with the recirculation pump or automated feature supply valves. 508.4.2.4 Warning. Where the ORP reading for the ozone system drops below 600 mV, approved audible and visual alarms shall be installed to alert bathers and facility staff. (renumber remaining sections) 222.0 therapy Pools. A pool of water that is specifically designed for physical therapy or rehabilitation purposes. SubStANtiAtiON: The proposed code language is based in part on the work of the Disinfection and Water Quality Technical Committee of the Model Aquatic Health Code (MAHC) (Section 4.7.3.3). Secondary disinfection systems are not currently addressed in the USPSHTC, and should be to safeguard public health and safety. NSF 50 is the appropriate reference standard for secondary disinfection systems. NSF 50 is already referenced in Table 1001.1. 75 A public aquatic venue that, due to its intended purpose, has a greater likelihood of becoming contaminated and/or provide bather to bather cross-contamination should be protected with a secondary disinfection system. Such public aquatic venues include wading pools, activity pools, and spray grounds where diaper-aged children are present, and therapy pools were a patient may have open wounds. Cryptosporidium parvum (A parasite that causes disease within the intestines that is spread through contaminated water) is highly resistant to primary disinfectants such as chlorine. Therefore, a combination of a primary disinfectant with a secondary disinfection system such as ultraviolet that inactivates the microorganism or ozone that kills the microorganism are necessary to safeguard the public. It is important for the UV system to be interlocked electrically with the recirculation pump so that if the UV equipment fails to produce the required dosage, as measured by the calibrated sensors, the aquatic venue will not function. An inline strainer should be installed downstream of the UV system to capture any broken lamp glass or quartz sleeve that could pose a safety hazard to the bathers. An ambient ozone gas monitor/controller is necessary in order to disable the ozone system in the event of an ozone gas leak. As with UV systems, an ozone system should be interlocked electrically with either the recirculation pump or aquatic venue supply valves so that if the ozone equipment fails to produce the required dosage, as measured by ORP, the aquatic venue will not function. The MAHC defines an “aquatic venue” as, “An artificially constructed or modified natural structure where the general public is exposed to water intended for recreational or therapeutic purposes.” This would include swimming pools, spas, hot tubs, water slides, catch pools, wave pools, leisure rivers, etc. COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 508.4.1.4 Warning. Where the UV system shuts down, an approved visual alarm shall be installed to alert bathers and facility staff. 508.4.2.4 Warning. Where the ORP reading for the ozone system drops below 600 mV, approved audible and visual alarms shall be installed to alert bathers and facility staff. COmmittee StAtemeNt: Section 508.4.1.4 and Section 508.4.2.4 are being modified as bathers cannot fix issues that may occur with an UV or ozone system. tOtAL eLiGibLe tO VOte: 12 VOtiNG reSuLtS: AFFIRMATIVE: 12 COmmeNt ON AFFirmAtiVe: OSiNSKi: Add flotation/sensory deprivation tanks, spas, swim school pools, and other heavily used or high bather load pools to the required list of aquatic venues that require secondary disinfection as they are all high risk venues.

Return inlets shall be installed in accordance with the manufacturer’s installation instructions. Return inlets shall not have sharp edges or present a hazard to bathers. Swimming pool, spa, and hot tub return inlets shall be sized based on the required turnover rates of Section 503.1, and shall be located in accordance with Section 508.6.1 and Section 508.6.2. 508.6.1 Swimming Pools. Where floor return inlets are used, the distance between inlets shall be not more than 20 feet (6096 mm). Floor return inlets shall be located not more than 15 feet (4572 mm) from adjacent walls. Floor return inlets shall be installed flush. Where wall return inlets are used, the distance between inlets shall be not more than 20 feet (6096 mm). A wall return inlet shall be located not more than 5 feet (1524 mm) from each corner of a pool. Where a swimming pool is more than 50 feet (15 240 mm) wide, a combination of floor and wall return inlets shall be installed. 508.6.2 Spas and Hot tubs. Not less than two equally spaced return inlets shall be installed in a spa or hot tub. The circulation system shall be separate from the hydrojet booster pump system. 210.0 Hydrojet booster Pump System. A system whereby one or more hydrojets are activated by the use of a pump that is completely independent of the filtration and heating system of the spa or hot tub. 211.0 220.0 return inlet Fitting. A fitting or fixture through which circulated or hydrojetted water enters the pool, spa, or hot tub. SubStANtiAtiON: An aquatic venue has to have a sufficient number of return inlets to ensure that the turnover rates of Section 503.1 are achieved. The method and placement of return inlets is critical for providing equal distribution of treated water throughout a pool, spa, or hot tub to avoid dead or stagnant areas. Without properly circulated water, the growth of algae and pathogens can occur rapidly. It is important for return inlets to not present a danger to the bathers by having sharp edges or presenting a tripping hazard. These provisions are based on industry standards and codes such as the Model Aquatic Health Code (MAHC). The circulation system needs to be separate from the hydrojet booster pump system since the hydrojet booster pump system operates on a timer system, whereas the circulation system continuously operates to maintain the water quality of the spa or hot tub. The definition for “hydrojet booster pump system” should be revised to account for both spas and hot tubs. The definition for “inlet fitting” has been changed to “return inlet” to be consistent with terminology used throughout the industry.

Equipment shall be so installed within the space it is located so as to provide ready accessibility for cleaning, operating, maintenance, and servicing. Equipment shall be so located that tThe equipment controls are shall not be capable of being accessed by unauthorized personnel. Equipment, unless designed for outdoor installation, shall be protected against the weather in an approved manner or installed within an enclosed room in accordance with Section 602.2. 604.0 equipment Foundations and enclosures. 604.1 General. Mechanical eEquipment installed outdoors shall be supported on level concrete or other approved base designed to handle the anticipated loads., and such base Equipment installed at ground level shall be not less than 3 inches (76 mm) above the adjoining ground level. Piping, equipment, and appurtenances shall be secured in accordance with the requirements of this code, the manufacturer’s installation instructions, and as approved by the Authority Having Jurisdiction. Heating and electrical equipment, unless approved for outdoor installation, shall be adequately protected against the weather or installed within a building. 602.1.1 marking. Equipment, piping, valves, and system components shall be marked in an approved manner to identify their function. System piping shall indicate direction of flow. 602.2 equipment rooms or enclosures. Floors shall be constructed of concrete or other nonabsorbent material in accordance with the building code, and shall be provided with an approved means of drainage in accordance with the plumbing code. Enclosed equipment rooms shall be adequately ventilated in accordance with the mechanical code. Combustion, HVAC, and electrical equipment shall not be located in the same room used for chemical storage, or exposed to chemical fumes or vapors. 602.2.1 indoor Access. Where access to an equipment room is made through an aquatic facility, a door shall be installed. The door shall be equipped with an automatic closer and lock, and a gasket or other approved means to prevent passage of air, fumes, or vapors. The floor of the equipment room shall be sloped away from the door to the aquatic facility. (renumber remaining sections) 604.2 405.12 Wooden Hot tubs. Wooden hot tubs, installed below grade, shall have not less than 12 inches (305 mm) of clearance between the outside walls of the tub and the interior wall of a supported sump or pit. SubStANtiAtiON: The proposed code language is based in part on the work of the Facility Design and Construction Technical Committee of the Model Aquatic Health Code (MAHC) (Section 4.9.1). In Section 602.1, it is important for equipment to be installed in accordance with the manufacturer’s installation instructions in order to provide a safe installation. The text “Equipment shall be so located,” is being deleted as it is redundant to language used in the second sentence. The text, “Piping, equipment, and appurtenances shall be secured in accordance with the requirements of this code, the manufacturer’s installation instructions, and as approved by the Authority Having Jurisdiction,” is not necessary as the section already states that equipment controls shall be located to prevent access by unauthorized personnel. The text, “Heating and electrical equipment, unless approved for outdoor installation, shall be adequately protected against the weather or installed within a building,” should be revised to correlate with the terminology used in Sections 602.2 and 602.2.1. Furthermore, the text, “Heating and electrical” should be deleted as this chapter should pertain to all types of mechanical equipment used for an aquatic facility (ex: pumps, recirculation equipment, etc.), and not just for heating and electrical purposes. 80 In Section 602.1.1, the direction of flow should be marked on system components and piping in order to properly operate and maintain the system. In Section 602.2, the construction of the floors; the installation of the drainage system; and the ventilation system for an equipment room or enclosure should be done in accordance with the applicable codes to safeguard public health and safety. Furthermore, it is critical for both the health and safety of the public, and the life of the equipment, that combustion, HVAC, and electrical equipment not be installed in the same room used for chemical storage. Some chemicals used for aquatic venues can cause corrosion within combustion equipment that can lead to potential dangers such as carbon monoxide poisoning. In Section 602.2.1, where access to an equipment room is made through an aquatic facility (ex: natatorium), a door must be installed and equipped with an automatic closer and lock to prevent unauthorized access. Furthermore, the door should be gasketed to prevent the passage of air, fumes, or vapors that could pose a health hazard to the bathers. The floor of the equipment room should slope back into the equipment room in such a way as to prevent any equipment-room spills from running under the door into the aquatic facility. Section 604.2 (Wooden Hot Tubs) should be relocated to Section 405.0 where the other provisions that pertain to the installation of spas and hot tubs are located. The MAHC defines an “aquatic facility” as, “A public facility that contains one or more aquatic venues and support infrastructure under a single management structure.” COmmittee ACtiON: Accept as Submitted tOtAL eLiGibLe tO VOte: 12 VOtiNG reSuLtS: AFFIRMATIVE: 12 81 USPSHTC 2015 – (605.1): Submitter: Marguerite Carroll UL LLC Item # 064 reCOmmeNDAtiON: Add new text as follows: 605.1 Application.

The revisions to Chapter 7, and deletion of Appendix B and applicable fuel gas venting definitions in Chapter 2, are being proposed as it does not make sense for the USPSHTC to provide fuel gas venting provisions that are not specific to swimming pool, spa, and hot tub installations. Therefore, this code change proposal maintains the code provisions within Chapter 7 that pertain to all types of water heating equipment, and deletes those provisions that pertain to fuel gas venting that are identical to those already found in the Uniform Plumbing Code (UPC) and Uniform Mechanical Code (UMC). 2. The revisions to Section 704.1 (General) provide the necessary fuel-gas water heating equipment installation, venting, and combustion air requirements for the end user by referencing the manufacturer’s installation instructions and the mechanical code, which is consistent in practice with other swimming pool, spa, and hot tub codes. 3. Chapter 7 pertains to all types of water heating equipment that utilize energy from other sources besides fuel gas. If it can be argued that the fuel gas venting provisions are necessary for the USPSHTC, then similar installation provisions that involve solar energy, electric, or heat pump should be provided as well.

Such provisions are more appropriately located in a mechanical code, which is consistent in practice with other swimming pool, spa, and hot tub codes. 2. Furthermore, it does not make sense to have such detailed fuel gas pipe provisions in the USPSHTC when other types of energy sources (such as: electric, solar, heat pump, etc.) are not provided with similar provisions as well.

Swimming pools shall have not less than two means of entry/exit located to serve both ends of the pool by means of steps, recessed steps, ladders, stairs, or combination thereof. One entry/exit shall be provided in the shallow area of the pool where the vertical distance from the bottom of the pool to the deck exceeds 2 feet (610 mm). A second means of entry/exit shall be provided in the deep area of a pool having a depth that exceeds 54 inches (1372 mm). Where the width of the pool exceeds 30 feet (9144 mm), such means of entry/exit shall be provided at each side, not more than 100 feet (30 480 mm) apart. Wading pools shall have not less than one means of entry/exit by means of steps, stairs, sloped zero-depth entry, or combination thereof.

Where zero-depth entries are provided for public aquatic venues, they shall be slip-resistant. The slope of a zero-depth entry shall not exceed 1 foot (305 mm) in 20 feet (6096 mm) to a water depth of 3 feet (914 mm). 228.0 Zero-Depth entry. An entry that starts at deck level and ends at the bottom of the aquatic venue. Also known as a beach entry or sloped entry. SubStANtiAtiON: Since zero-depth entries are a common form of entry for shallow depth pools, provisions to safeguard public health and safety should be provided for installation and enforcement. Within the pool industry, a slip-resistant surface is considered one that has a coefficient of friction of not less than 0.6. However, it is not practical that all jurisdictions will have the equipment necessary (ex: binary output tribometer) to perform field testing for enforcement. It should also be noted, that the text “slip-resistant surface” is consistent with the terminology used within the building code for enforcement of walking surfaces that are part of a means of egress. The Model Aquatic Health Code (MAHC) defines an “aquatic venue” as, “An artificially constructed or modified natural structure where the general public is exposed to water intended for recreational or therapeutic purposes.” This would include swimming pools, spas, hot tubs, water slides, catch pools, wave pools, leisure rivers, etc. COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 902.1 Swimming Pools.

(portions of table not shown remain unchanged) 138 SubStANtiAtiON: The proposed code language is based in part on the work of the Facility Design and Construction Technical Committee of the Model Aquatic Health Code (MAHC) (Section 4.12.2). Aquatic features such as water slides, flumes, slide run-outs, and catch pools are not currently addressed in the USPSHTC, and should be to safeguard public health and safety. The structural design and operation of a water slide system should comply with the industry standard for such systems (ASTM F2376). Means for disinfection of the water used for a water slide have to meet the requirements of the code to avoid sickness or disease. Handholds are necessary for allowing a bather to safely position themselves before entering a water slide. ASTM F2376 (Section 8.2.1) requires either handrails or guardrails to be used as handholds. The 2 inch maximum size for the handholds is based on the hand size of an average adult that is consistent with industry standards and practices. A flume should be designed and constructed to prevent injury or death to the bather by preventing surface injuries such as abrasions and cuts, and ensuring that the bather is safely within the flume at all times of operations to prevent fall-related accidents. Water slide manufacturers (such as ProSlide Technology, WhiteWater, or Splashtacular) typically provide installation instructions for ensuring that a bather safely enters a slide run-out or catch pool to avoid injury. The minimum water depth for a catch pool, based on industry standards, shall be not less than 42 inches to minimize impact with the pool bottom. However, as indicated in Section 1004.1.2, if the manufacturer requires a deeper catch pool due to such factors as the height of the slide above the water surface or the flow velocity of the water, than the catch pool shall be deeper than 42 inches. The requirement for one means of exit is consistent with the provisions already located in Section 902.1 of the USPSHTC. Furthermore, in order to prevent injury the means of exit has to be located away from where the water slide or flume terminates into the catch pool.

Openings in a caisson shall be designed to prevent the passage of a 4 inch (102 mm) diameter sphere. Not less than two emergency shut-off switches (one on each side) shall be provided to disable the wave action, and shall be located such that the switches or wave generation equipment are not capable of being accessed by unauthorized personnel. An automatic audible warning system shall be provided to indicate the beginning of wave generation.

SubStANtiAtiON: The proposed code language is based in part on the work of the Facility Design and Construction Technical Committee of the Model Aquatic Health Code (MAHC) (Section 4.12.3). This code language provides provisions to safeguard public health and safety in regards to wave pools, and addresses a gap in the current version of the USPSHTC. In order to prevent injury, caissons must be separated from areas used by the bathers in accordance with the AHJ, and shall not have openings large enough to pass a 4 inch diameter sphere. The 4 inch diameter sphere requirement is consistent with industry standards for openings in safety barriers (refer to Section 903.3.1 of the USPSHTC). Shut-off switches are necessary in the case of an emergency. Such switches and wave generation equipment shall only be accessible to authorized personnel to prevent injury to the bathers. An audible warning system is necessary to alert bathers of the beginning of wave action. No diving signage shall be provided to alert bathers of a potential safety hazard except where the perimeter of the pool is not accessible to the bathers or at zero-depth entries. Entry and exit to and from a wave pool has to be strictly governed to avoid a collision or entrapment hazard. That is why access can only be gained by way of a zero-depth entry, and exit by way of a ladder installed flush with the pool wall. Handholds are necessary to assist a bather in distress, and must also be installed flush with the pool wall to avoid a safety hazard. The 2 inch maximum size for the handholds is based on the hand size of an average adult that is consistent with industry standards and practices. 141 COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 902.3 Wave Pools.

A leisure river shall be provided with a means of emergency exit that consists of steps, recessed steps, ladders, stairs, or combination thereof that do not protrude into the river, and are located at not more than 150 foot (45 720 mm) intervals around the river. Handholds shall be provided continuously on not less than one side of the river where the water depth exceeds 24 inches (610 mm), and located not more than 6 inches (152 mm) above the water surface. Handholds shall consist of coping, or other approved methods, that are not more than 2 inches (51 mm) in size. (renumber remaining sections) 214.0 Leisure river. A manufactured stream in which water is moved by propulsion to provide a river-like flow that transports bathers over a defined path that may include water features and play devices. Also known as a watercourse ride. SubStANtiAtiON: The proposed code language is based in part on the work of the Facility Design and Construction Technical Committee of the Model Aquatic Health Code (MAHC) (Section 4.12.5). This code language provides provisions to safeguard public health and safety in regards to leisure rivers, and addresses a gap in the current version of the USPSHTC. A perimeter deck is needed on at least one side of a leisure river for supervision, emergency exit, and maintenance purposes unless otherwise approved by the AHJ. The 4 foot width is consistent with Section 417.0 of the USPSHTC. Most rivers are 3 to 31⁄2 feet deep making the clearance 7 to 71⁄2 feet if you adhere to the 4 foot clearance requirement above the water surface. It should be noted that 7 feet is the typical building code minimum height requirement for ceilings. In order to prevent a collision or entrapment hazard, propulsion jets should be installed flush with the wall or bottom of the leisure river. It is important that a means of emergency exit be provided for patrons that fall into a leisure river as such attractions tend to be constructed with side walls that make it difficult for one to exit. An emergency exit should not protrude within the river that could create a collision or entrapment hazard for patrons. The 150 foot distance will make it so that a patron will never be more than 75 feet, or 21⁄2 minutes based on an average current flow rate of 1 to 4 feet per second, from an emergency exit. The sides of a leisure river are the necessary point of safety for a patron that falls into the river, and therefore handholds are necessary in order for a patron to grasp when in distress. The 2 inch maximum size for the handholds is based on the hand size of an average adult that is consistent with industry standards and practices. 143 COmmittee ACtiON: Reject COmmittee StAtemeNt: The deck and emergency exit requirements lack sufficient technical justification to warrant such costly provisions. tOtAL eLiGibLe tO VOte: 12 VOtiNG reSuLtS: AFFIRMATIVE: 12 144 USPSHTC 2015 – (1007.0, 1007.1, 203.0, 221.0): Submitter: Jasen Kunz, MPH, REHS/RS Centers for Disease Control and Prevention (CDC) Item # 083 reCOmmeNDAtiON: Revise text as follows: 1007.0 Spray Grounds. 1007.1 General.

Not less than a 8 foot (2438 mm) wide deck that is constructed in accordance with Section 417.0, or a solid barrier constructed in accordance with Section 903.3.2, shall be provided between a spray ground and a landscaped area. A barrier of not less than 4 feet (1219 mm) in height shall be installed between a spray ground and another body of water located within the same aquatic facility, unless there is a separation distance of not less than 15 feet (4572 mm). The velocity of a spray ground feature shall not exceed 20 feet per second (ft/s) (6.1 m/s). 203.0 221.0 Aquatic Playgrounds Spray Ground. An specific area incorporating shallow water used for interactive water play that includes water sprays or other water features of various shapes and sizes. 221.0 Spray Ground Feature. A device used for the purpose of spraying or dumping water on patrons. SubStANtiAtiON: The proposed code language is based in part on the work of the Facility Design and Construction Technical Committee of the Model Aquatic Health Code (MAHC) (Section 4.12.8). This code language provides provisions to safeguard public health and safety in regards to spray grounds, and addresses a gap in the current version of the USPSHTC. In order to provide a safe and sanitary facility, a spray ground must have a surface that is both nonabrasive to prevent injuries when falls occur, and slip-resistant to prevent falls as much as possible. Within the pool industry, a slipresistant surface is considered one that has a coefficient of friction of not less than 0.6. However, it is not practical that all jurisdictions will have the equipment necessary (ex: binary output tribometer) to perform field testing in order to enforce. It should also be noted, that the text “slip-resistant surface” is consistent with the terminology used within the building code for enforcement of walking surfaces that are part of a means of egress. The surface of a spray ground should also be capable of withstanding repeated cleanings when accidents occur (ex: messy diaper). Standing water should not accumulate on a spray ground as an unsanitary condition can occur such as the breeding ground for mosquitoes that carry disease. Therefore, a uniform slope of not less than ¼ of an inch per foot, or as required by the AHJ, is necessary to prevent the accumulation of water. A minimum slope of ¼ inch per foot, or 2%, is consistent with the requirements of the plumbing code. Drainage flow should be by gravity, and not by direct suction, to avoid injury to a child that may sit on the drainage outlets. Landscaped areas should be separated from a spray ground by a deck or solid barrier to prevent contamination of the water that is supplied to the aquatic venue. Other methods of separation such as planters could be accepted by the AHJ based on Section 302.6 (Alternate Materials and Methods of Construction Equivalency). 145 As with wading pools, a spray ground needs to be separated from another body of water located within the same facility to make it difficult for small children to access, and therefore preventing unnecessary accidents from occurring. The 4 foot barrier height is based on language used in Section 404.1 of the USPSHTC for wading pools. The velocity of a spray ground feature should not exceed 20 ft/s in order to prevent eye injury to the bather. The MAHC defines an “aquatic facility” as, “A public facility that contains one or more aquatic venues and support infrastructure under a single management structure.” COmmittee ACtiON: Accept as Amended by the TC Amend proposal as follows: 1007.0 Spray Grounds. 1007.1 General.

Drainage flow to the spray ground treatment tank shall be by gravity. Openings in drain covers shall not exceed 1⁄2 of an inch (12.7 mm) in size.

Determine the required combination of indoor and outdoor combustion air opening sizes for the following appliance installation example. PR E- Example Installation: A fan-assisted furnace and draft hoodequipped water heating equipment with the following inputs are located in a 15 foot (4572 mm) by 30 foot (9144 mm) basement with an 8 foot (2438 mm) ceiling. No additional indoor spaces shall be used to help meet the appliance combustion air needs. Fan-Assisted Furnace Input: 100 000 British thermal units per hour (Btu/h) (29 kW) Draft Hood-Equipped Water Heating Equipment Input: 40 000 Btu/h (11.7 kW) Solution: (1) Determine the total available room volume. Equipment room volume: 15 feet (4572 mm) by 30 feet (9144 mm) with an 8 foot (2438 mm) ceiling = 3600 cubic feet (101.94 m3) (2) Determine the total required volume. The standard method to determine combustion air shall be used to calculate the required volume. The combined input for the appliances located in the basement is calculated as follows: 100 000 Btu/h (29 kW) + 40 000 Btu/h (11.7 kW) = 140 000 Btu/h (41 kW) 178 24 x 28 INSIDE DIAMETER OR EQUIVALENT DIAMETER (inches) T Example: Offset common vent NOMINAL LINER SIZE (inches) 201⁄4 x 241⁄4 30 x 30 251⁄2 x 251⁄2 30 x 36 251⁄2 x 311⁄2 36 x 36 311⁄2 x 311⁄2 4.0 5.0 6.0 7.0 7.4 8.0 9.0 10.0 10.4 11.0 11.8 12.0 14.0 14.5 15.0 16.2 18.0 18.2 20.0 20.1 22.0 22.1 24.0 24.1 26.4 27.0 27.9 30.0 30.9 33.0 34.4 36.0 EQUIVALENT AREA (square inches) 12.2 19.6 28.3 38.3 42.7 50.3 63.6 78.5 83.3 95.0 107.5 113.0 153.9 162.9 176.7 206.1 254.4 260.2 314.1 314.2 380.1 380.1 452.3 456.2 543.3 572.5 607.0 706.8 749.9 855.3 929.4 1017.9 For SI units: 1 inch = 25.4 mm, 1 square inch = 0.000645 m2 *Where liner sizes differ dimensionally from those shown in this table, equivalent diameters shall be permitted to be determined from published tables for square and rectangular ducts of equivalent carrying capacity or by other engineering methods. The standard method requires that the required volume be determined based on 50 cubic feet per 1000 Btu/h (4.83 m3/kW). Using Table B 2.1, the required volume for a 140 000 Btu/h (41 kW) water heating equipment is 7000 cubic feet (198.22 m3). Conclusion: Indoor volume is insufficient to supply combustion air since the total of 3600 cubic feet (101.94 m3) does not meet the required volume of 7000 cubic feet (198.22 m3). 2015 UNIFORM SWIMMING POOL, SPA, AND HOT TUB CODE APPENDIX B (3) Determine ratio of the available volume to the required volume: 3600 cubic feet 7000 cubic feet = 0.51 (4) Determine the reduction factor to be used to reduce the full outdoor air opening size to the minimum required based on ratio of indoor spaces: 1.00 – 0.51 (from Step 3) = 0.49 140 000 Btu/h 3000 British thermal units per square inch (Btu/in2) APPLIANCE INPUT (Btu/h) 5000 10 000 15 000 20 000 25 000 30 000 35 000 40 000 45 000 50 000 55 000 60 000 65 000 70 000 75 000 80 000 85 000 90 000 95 000 100 000 105 000 110 000 115 000 120 000 125 000 130 000 135 000 140 000 145 000 150 000 160 000 170 000 180 000 190 000 200 000 210 000 220 000 230 000 240 000 250 000 260 000 270 000 280 000 290 000 300 000 PR IN (5) Determine the single outdoor combustion air opening size as where combustion air is to come from outdoors.

USEFUL TABLES METRIC SYSTEM (INTERNATIONAL SYSTEM OF UNITS – SI) For the users of this code, we are including a short explanation and some conversion tables to aid in the conversion of our familiar English units to the forthcoming SI units. This is written with the code users in mind, and will detail only those measurements used in everyday work and calculations. For the scientific units, we recommend the use of ANSI Z210.1, "Metric Practice Guide." PR E- PR IN T GENERAL COMMENTS Our present system of measuring involves the three dimensions of force, length and time. The SI units involve mass, length, and time. The change of force to mass has meaning in scientific and engineering work, but for practical use in ordinary construction, we will show kilogram to pounds conversion values, although an exact conversion would be pounds force divided by the acceleration due to gravity to mass units. In the same manner, the SI units for temperature expressed in Kelvins and based on absolute zero will be given as degrees Celsius, which is the more familiar and practical Centigrade degrees. The SI system measures angles in radians where there are 2 pi radians in a circle, but using a 1.5708 bend to change from a vertical stack to a horizontal house drain is not as easy as calling out a 1⁄4 bend or an ell for water piping. The foregoing notes are intended to show that in making conversions from one unit system to another, a little common sense must be used and the degree of accuracy needed to do the job at hand. The following tables are set up using this approach and using the preferred SI units. 184 2015 UNIFORM SWIMMING POOL, SPA, AND HOT TUB CODE USEFUL TABLES UNIT CONVERSIONS PR MULTIPLY BY 76.0 1055.056 0.000293 0.293 6.283 0.0283 28.32 0.0283 0.4719 1.64 x 10-5 0.01639 264.17 0.76455 0.0175 (°F-32)/1.8 0.3048 304.8 0.3048 1.356 2.260 x 10-5 1.356 x 10-3 3.785 4.3 x 10-5 0.063 6.479 x 10-5 0.7457 2.684 x 10+6 0.7457 25.4 25.4 3.3863 9.480 x 10-4 0.7376 2.778 x 10-4 2.2046 1.102 x 10-3 0.6214 0.6214 3412.14 1.341 3413 2.655 x 10+6 3.6 x 10+6 0.03531 0.2642 T Centimeters of mercury Joules Kilowatts Watts Radians Cubic meters Liters Cubic meters/hour Liters/second Cubic meters Liters Gallons (U.S. liquid) Cubic meters Radians Celsius Meters Millimeters Meters/second Joules Kilowatts Kilowatts Liters Liters/second Liters/second Kilograms Kilowatts Joules Kilowatt-hours Millimeters Millimeters/hour KiloPascals Btus Foot-pounds Watt-hours Pounds Tons (short) Miles (statute) Miles/hour Btus/hour Horsepower Btus Foot-pounds Joules Cubic feet Gallons (U.S. liquid) E- Atmosphere British thermal units (Btu) Btus/hour Btus/hour Circumference Cubic feet Cubic feet Cubic feet/hour Cubic feet/minute Cubic inches Cubic inches Cubic meters Cubic yards Degrees Fahrenheit Feet Feet Feet/second Foot-pounds Foot pounds-force/minute Foot pounds-force/second Gallons Gallons/day Gallons/minute Grains Horsepower Horsepower-hours Horsepower-hours Inches Inches/hour Inches of mercury (0°C) Joules Joules Joules Kilograms Kilograms Kilometers Kilometers/hour Kilowatts Kilowatts Kilowatt-hours Kilowatt-hours Kilowatt-hours Liters Liters INTO PR IN TO CONVERT 2015 UNIFORM SWIMMING POOL, SPA, AND HOT TUB CODE 185 USEFUL TABLES INTO Feet Inches Yards Feet/second Miles/hr Kilometers Meters/minute Inches Kilograms Kilograms Kilograms/meters KiloPascals Liters Degrees Square meters Square meters Square millimeters Square inches Square inches KiloPascals Btus/hour Horsepower 3.281 39.37 1.094 3.281 2.237 1.609 26.82 0.03937 0.02834 0.4536 1.4881 6.8947 0.9463 57.30 0.0929 6.45 x 10-4 645.16 1550 1.550 x 10-3 0.24908 3.4121 1.341 x 10-3 PR IN Meters Meters Meters Meters/second Meters/second Miles (statute) Miles/hour Millimeters Ounces (fluid) Pounds Pounds/foot Pounds-force/square inch Quarts (liquid) Radians Square feet Square inches Square inches Square meters Square millimeters Water column (1 inch) Watts Watts MULTIPLY BY T TO CONVERT UNIT CONVERSIONS (continued) PR E- When the plumbing industry, including plumbers, suppliers, and manufacturers, actually begins the metric conversion program, it will undoubtedly follow the guidelines of committees selected from all phases of the construction industry as set up under the American National Metric Council. The final preferred units used will be those that apply to our industry and will be of the magnitude to simplify and ease job calculations and avoid confusion and ambiguity. The conversion looks complex and confusing, but when the metric system was first proposed in France, an attempt was made to include a ten-hour day, a ten-day week, and ten months to the year, but cooler heads prevailed and our time still follows the sun and seasons. Likewise, assigning new units or numbers to the quantities we must work with cannot change the basic hydraulic principles that plumbers have worked with throughout history.
