Introduction Development PREFACE The International Swimming Pool and Spa Code' (ISPSC) establishes minimum requirements for the design, construction, alteration, repair and maintenance of swimming pools, spas, hot tubs and aquatic facilities. This 2018 edition is fully compatible with all of the International Codes' (I -Codes®) published by the International Code Council` (ICC®), including the International Building Codes, International Energy Conservation Codes, International Existing Building Code®, International Fire Code', International Fuel Gas Codes, International Green Construction Code', International Mechanical Code®, International Plumbing Code®, International Private Sewage Disposal Codes, International Property Maintenance Code®, International Residential Codes, International Wildland- Urban Interface Code®, International Zoning Code® and International Code Council Performance Code®. The I -Codes, including this International Swimming Pool and Spa Code, are used in a variety of ways in both the public and private sectors. Most industry professionals are familiar with the (- Codes as the basis of laws and regulations in communities across the U.S. and in other countries. However, the impact of the codes extends well beyond the regulatory arena, as they are used in a variety of nonregulatory settings, including: • Voluntary compliance programs such as those promoting sustainability, energy efficiency and disaster resistance. • The insurance industry, to estimate and manage risk, and as a tool in underwriting and rate decisions. • Certification and credentialing of individuals involved in the fields of building design, con- struction and safety. • Certification of building and construction -related products. • U.S. federal agencies, to guide construction in an array of government -owned properties. • Facilities management. • 'Best practices" benchmarks for designers and builders, including those who are engaged in projects in jurisdictions that do not have a formal regulatory system or a governmental enforcement mechanism. • College, university and professional school textbooks and curricula. • Reference works related to building design and construction. In addition to the codes themselves, the code development process brings together building pro- fessionals on a regular basis. It provides an international forum for discussion and deliberation about building design, construction methods, safety, performance requirements, technological advances and innovative products. This 2018 edition presents the code as originally issued, with changes as reflected in the 2015 edi- tion and further changes approved by the ICC Code Development Process through 2017. A new edi- tion such as this is promulgated every 3 years. This code is founded on principles intended to establish provisions consistent with the scope of a swimming pool and spa code that adequately protects public health, safety and welfare; provisions that do not unnecessarily increase construction costs; provisions that do not restrict the use of new materials, products or methods of construction; and provisions that do not give preferential treat- ment to particular types or classes of materials, products or methods of construction. 2018 INTERNATIONAL SWIMMING POOL AND SPA CODE® iii Licensed to Susan Ballard.

Maintenance The International Swimming Pool and Spa Code is kept up to date through the review of proposed changes submitted by code enforcement officials, industry representatives, design professionals and other interested parties. Proposed changes are carefully considered through an open code development process in which all interested and affected parties may participate. The ICC Code Development Process reflects principles of openness, transparency, balance, due process and consensus, the principles embodied in OMB Circular A-119, which governs the federal government's use of private -sector standards. The ICC process is open to anyone; there is no cost to participate, and people can participate without travel cost through the ICC's cloud -based app, cdp- Access"'. A broad cross section of interests are represented in the ICC Code Development Process. The codes, which are updated regularly, include safeguards that allow for emergency action when required for health and safety reasons. In order to ensure that organizations with a direct and material interest in the codes have a voice in the process, the ICC has developed partnerships with key industry segments that support the ICC's important public safety mission. Some code development committee members were nomi- nated by the following industry partners and approved by the ICC Board: • Association of Pool and Spa Professionals (APSP) • American Institute of Architects (AIA) The code development committees evaluate and make recommendations regarding proposed changes to the codes. Their recommendations are then subject to public comment and council -wide votes. The ICC's governmental members —public safety officials who have no financial or business interest in the outcome —cast the final votes on proposed changes. The contents of this work are subject to change through the code development cycles and by any governmental entity that enacts the code into law. For more information regarding the code devel- opment process, contact the Codes and Standards Development Department of the International Code Council. While the I -Code development procedure is thorough and comprehensive, the ICC, its members and those participating in the development of this code disclaim any liability resulting from the pub- lication or use of the I -Codes, or from compliance or noncompliance with their provisions. The ICC does not have the power or authority to police or enforce compliance with the contents of this code. Code Development Committee Responsibilities (Letter Designations in Front of Section Numbers) In each code development cycle, code change proposals to this code are considered at the Commit- tee Action Hearing by the International Swimming Pool and Spa Code Development Committee, whose action constitutes a recommendation to the voting membership for final action on the pro- posed change. Code change proposals to sections of the code that are preceded by a bracketed let- ter designation, such as [A], will be considered by a committee other than the Swimming Pool and Spa Code Development Committee. For example, proposed changes to Section [A] 102.1 will be considered by the Administrative Code Development Committee during the Committee Action Hearings in the 2019 (Group B) code development cycle. The bracketed letter designations for committees responsible for portions of this code are as fol- lows: [A] = Administrative Code Development Committee; and [BS] = IBC —Structural Code Development Committee For the development of the 2021 edition of the I -Codes, there will be two groups of code devel- opment committees and they will meet in separate years. Note that these are tentative groupings. iv 2018 INTERNATIONAL SWIMMING POOL AND SPA COIDE® Licensed to Susan Ballard. ANSI store order # X_763600. Downloaded 10/25/2021. Single user license only.

Code change proposals submitted for code sections that have a letter designation in front of them will be heard by the respective committee responsible for such code sections. Because differ- ent committees hold Committee Action Hearings in different years, proposals for this code will be heard by committees in both the 2018 (Group A) and the 2019 (Group B) code development cycles. Note that every section of Chapter 1 of this code is designated as the responsibility of the Admin- istrative Code Development Committee, and that committee is part of the Group B portion of the code hearings. This committee will hold its code development hearings in 2019 to consider all code change proposals for Chapter 1 of this code and proposals for Chapter 1 of all I -Codes except the International Energy Conservation Code, International Residential Code and International Green Construction Code. Therefore, any proposals received for Chapter 1 of this code will be assigned to the Administrative Code Development Committee for consideration in 2019. It is very important that anyone submitting code change proposals understand which code devel- opment committee is responsible for the section of the code that is the subject of the code change proposal. For further information on the code development committee responsibilities, please visit the ICC website at www.iccsafe.org/scoping. 2018 INTERNATIONAL SWIMMING POOL AND SPA CODE® Licensed to Susan Ballard.

Marginal Markings Solid vertical lines in the margins within the body of the code indicate a technical change from the requirements of the 2015 edition. Deletion indicators in the form of an arrow (m*) are provided in the margin where an entire section, paragraph, exception or table has been deleted or an item in a list of items or a table has been deleted. Coordination of the International Codes Italicized Terms Adoption The coordination of technical provisions is one of the strengths of the ICC family of model codes. The codes can be used as a complete set of complementary documents, which will provide users with full integration and coordination of technical provisions. Individual codes can also be used in subsets or as stand-alone documents. To make sure that each individual code is as complete as pos- sible, some technical provisions that are relevant to more than one subject area are duplicated in some of the model codes. This allows users maximum flexibility in their application of the I -Codes. Words and terms defined in Chapter 2, Definitions, are italicized where they appear in code text and the Chapter 2 definition applies. Where such words and terms are not italicized, common -use defi- nitions apply. The words and terms selected have code -specific definitions that the user should read carefully to facilitate better understanding of the code. The International Code Council maintains a copyright in all of its codes and standards. Maintaining copyright allows ICC to fund its mission through sales of books, in both print and electronic formats. The ICC welcomes adoption of its codes by jurisdictions that recognize and acknowledge the ICC's copyright in the code, and further acknowledge the substantial shared value of the public/private partnership for code development between jurisdictions and the ICC. The ICC also recognizes the need for jurisdictions to make laws available to the public. All I -Codes and I -Standards, along with the laws of many jurisdictions, are available for free in a nondownload- able form on the ICC's website. Jurisdictions should contact the ICC at adoptions@iccsafe.org to learn how to adopt and distribute laws based on the International Swimming Pool and Spa Code in a manner that provides necessary access, while maintaining the ICC's copyright. To facilitate adoption, several sections of this code contain blanks for fill-in information that needs to be supplied by the adopting jurisdiction as part of the adoption legislation.

EFFECTIVE USE OF THE INTERNATIONAL SWIMMING POOL AND SPA CODE The International Swimming Pool and Spa Code (ISPSC) is a model code that regulates the minimum requirements for the design, construction, alteration, repair and maintenance of swimming pools, spas, hot tubes and aquatic facilities. This includes public swimming pools, public spas, public exer- cise spas, aquatic recreation facilities, onground storable residential pools, permanent inground residential pools, permanent residential spas, permanent residential exercise spas, portable resi- dential spas and portable residential exercise spas. In many jurisdictions, in addition to code officials having the responsibility for reviewing plans and inspecting the construction of pools and spas, environmental health officials also have a responsibility for oversight of the operation of pools and spas. In order to prevent disease and pre- vent injuries, environmental health officials conduct operational evaluations (inspections). This may include water chemistry, credentials and training of pool operators and lifeguards, proper water cir- culation, facility staff's preparedness to respond to injuries and accidents, and proper sanitation and safety of the facility. Code officials and environmental health officials commonly work closely in the plan review and inspection of pools and spas. This collaboration between departments to jointly review plans and inspect pools and spas is critical in order to achieve a safe and healthy environment for all that uti- lize these facilities. The Association of Pool & Spa Professionals (APSP), a cooperating sponsor with ICC in the devel- opment and update of the ISPSC, further notes: "While it is recognized that proper construction and installation are essential, safe use of pools and spas requires common sense, including constant adult supervision of children, and proper maintenance. It is assumed and intended that pool users will exercise appropriate personal judgment and responsibility (including constant adult supervision of children) and that operators will create and enforce rules and warning appropriate for their pool/ spa." Arrangement and Format of the 2018 ISPSC The format of the ISPSC allows each chapter to be devoted to a particular subject with the exception of Chapter 3 which contains general compliance subject matter that is coordinated with the provi- sions for each type of pool and spa regulated in Chapters 4-10. The ISPSC is divided into eleven dif- ferent parts: Chapter Subject 1 Scope and Administration 2 Definitions 3 General Compliance 4 Public Swimming Pools 5 Public Spas and Public Exercise Spas 6 Aquatic Recreation Facilities 7 Onground Storable Residential Swimming Pools 8 Permanent Inground Residential Swimming Pools 9 Permanent Residential Spas and Permanent Residential Exercise Spas 10 Portable Residential Spas and Portable Residential Exercise Spas 11 Referenced Standards 2018 INTERNATIONAL SWIMMING POOL AND SPA CODES vii Licensed to Susan Ballard.

The following is a chapter -by -chapter synopsis of the scope and intent of the provisions of the International Swimming Pool and Spa Code: Chapter 1 Scope and Administration. This chapter contains provisions for the application, enforcement and administration of subsequent requirements of the code. Chapter 1 identifies which swimming pools and spas come under its purview. It is largely concerned with maintaining "due process of law" in enforcing the design and construction criteria contained in the body of the code. Only through careful observation of the administrative provisions can the code official reason- ably expect to demonstrate that "equal protection under the law" has been provided. Chapter 2 Definitions. Terms that are defined in the code are listed alphabetically in Chapter 2. While a defined term may be used in one chapter or another, the meaning provided in Chapter 2 is applicable throughout the code. Where understanding of a term's definition is especially key to or necessary for the understand- ing of a particular code provision, the term is shown in italics wherever it appears in the code. This is true only for those terms that have a meaning that is unique to the code. In other words, the gener- ally understood meaning of a term or phrase might not be sufficient or consistent with the meaning prescribed by the code; therefore, it is essential that the code -defined meaning be known. Guidance regarding tense, gender and plurality of defined terms as well as guidance regarding terms not defined in this code is provided. Chapter 3 General Compliance. Chapter 3 is broad in scope. It includes a variety of require- ments for pools and spas. This chapter provides requirements that are intended to maintain a mini- mum level of safety and sanitation for both the general public and the users of pools or spas. Chapter 3 provides specific criteria for electrical, plumbing, mechanical and fuel gas requirements; energy savings requirements; construction in flood hazard areas; barrier requirements; decks around pools and spas; general design; dimensional design; equipment; suction entrapment avoid- ance; circulation systems; filters; pumps and motors; return and suction fittings; skimmers; heaters; air blowers and air induction systems; water supply; sanitizing equipment; wastewater disposal; lighting; ladders and recessed treads; and safety. It is important to note that Chapter 3 is intended to provide general requirements not found in Chapters 4-10. Chapters 4-10 specifically reference Chapter 3 in order to coordinate the general provisions with the specific provisions based on the type of pool or spa. Chapter 4 Public Swimming Pools. The purpose of Chapter 4 is to set forth specific require- ments in the code for public swimming pools with regard to diving equipment, bather load limita- tions, rest ledges, wading pools, decks, deck equipment, filters, dressing and sanitary facilities, special features and signage. The term "public swimming pool" is defined in Chapter 2 and includes the different classes of pools (Class A — Class F). Chapter 5 Public Spas and Public Exercise Spas. Chapter 5 establishes the specific criteria for public spas and public exercise spas with regard to materials, structure and design, pumps and motors, return and suction fittings, heater and temperature requirements, water supply, sanitation, oxidation equipment and chemical feeders, and safety features. The term "spa" is defined in Chap- ter 2. Chapter 6 Aquatic Recreation Facilities. The purpose of Chapter 6 is to establish specific requirements for aquatic recreation facilities with regard to floors, markings and indications, circu- lation systems, handholds and ropes, depths, barriers, number of occupants, toilet rooms and bath- rooms, special features and signage. The term "aquatic recreation facility" is defined in Chapter 2 and includes wave pools, leisure rivers, inner tube rides and body slides, to name a few. Chapter 7 Onground Storable Residential Swimming Pools. The purpose of Chapter 7 is to establish specific requirements for onground storable residential swimming pools with regard to ladders and stairs, decks and circulation systems. The term "onground storable pool" is defined in Chapter 2. This chapter applies to what has been commonly referred to in past standards and codes as onground or above -ground pools. The application of the provisions for onground residential pools is limited to pools associated with detached one- and two-family dwellings and townhouses not more than three stories high in accordance with the definition of the term "residential" in Chap- ter 2. viii 2018 INTERNATIONAL SWIMMING POOL AND SPA CODE® Licensed to Susan Ballard. ANSI store order # X_763600. Downloaded 10/25/2021. Single user license only. Copying and networking prohibited. Chapter 8 Permanent Inground Residential Swimming Pools. The purpose of Chapter 8 is to establish specific requirements for permanent inground residential swimming pools with regard to design, construction tolerances, diving water envelopes, walls, offset ledges, pool floors, diving equipment, special features, circulation systems and safety features. The application of the provi- sions for inground residential pools is limited to pools associated with detached one- and two-fam- ily dwellings and townhouses not more than three stories high in accordance with the definition of the term "residential" in Chapter 2. Chapter 9 Permanent Residential Spas and Permanent Residential Exercise Spas. The purpose of Chapter 9 is to establish specific requirements for permanent residential spas and per- manent residential exercise spas with regard to safety features. The application of the provisions for residential spas ("spa" is defined in Chapter 2) is limited to spas associated with detached one- and two-family dwellings and townhouses not more than three stories high in accordance with the defi- nition of the term "residential" in Chapter 2. Chapter 10 Portable Residential Spas and Portable Residential Exercise Spas. The pur- pose of Chapter 10 is to establish specific requirements for portable residential spas and portable residential exercise spas with regard to standards that the equipment must meet. The application of the provisions for residential spas ("spa" is defined in Chapter 2) is limited to spas associated with detached one- and two-family dwellings and townhouses not more than three stories high in accor- dance with the definition of the term "residential" in Chapter 2. Chapter 11 Referenced Standards. The code contains numerous references to standards that are used to regulate materials and methods of construction. Chapter 11 contains a comprehensive list of all standards that are referenced in the code. The standards are part of the code to the extent of the reference to the standard. Compliance with the referenced standard is necessary for compli- ance with this code. By providing specifically adopted standards, the construction and installation requirements necessary for compliance with the code can be readily determined. The basis for code compliance is, therefore, established and available on an equal basis to the code official, contractor, designer and owner. Chapter 11 is organized in a manner that makes it easy to locate specific standards. It lists all of the referenced standards, alphabetically, by acronym of the promulgating agency of the standard. Each agency's standards are then listed in either alphabetical or numeric order based on the stan- dard identification. The list also contains the title of the standard; the edition (date) of the standard referenced; any addenda included as part of the ICC adoption; and the section or sections of this code that reference the standard. 2018 INTERNATIONAL SWIMMING POOL AND SPA CODE" ix Licensed to Susan Ballard.

American National Standard Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standard developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved this standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Important Notice about this Document This voluntary standard has been developed under the published procedures of the American National Standards Institute (ANSI). The ANSI process brings together volunteers representing varied viewpoints and interests to achieve consensus. APSP does not write the standards. Rather, APSP facilitates a forum for its members, and others interested in pool and spa design and safety, to develop standards through the consensus procedures of the American National Standards Institute (ANSI).

Foreword This Foreword is not part of the American National Standard ANSI/APSP/ICC-7 2013. It is included for information only. The ANSI/APSP/ICC-7 2013 Standard for Suction Entrapment Avoidance in Swininr ing Pools, Wading Pools, Spas, Hot Tubs And Catch Basins was approved by ANSI on October 8, 2013. The objective of this voluntary standard is to provide recommended minimum guidelines for suction entrapment avoidance in the design, equipment, operation, and installation of new and existing swimming pools, wading pools, spas, hot tubs, and catch basins for builders, installers, pool operators, and service professionals. It is intended to meet the needs for incorporation into national or regional building codes, and also for adoption by state and/or local municipalities as a local code or ordinance. It is understood that for the sake of applicability and enforceability, the style and format of the standard may need adjustment to meet code or ordinance style of the jurisdiction adopting this document. The design recommendations and construction practices in this standard are based upon sound engineering principles, research, and field experience that, when applied properly, contribute to the delivery and installation of a safe product. The words "safe" and "safety" are not absolutes. While the goal of this standard is to design and construct a safe, enjoyable product, it is recognized that risk factors cannot, as a practical matter, be reduced to zero in any human activity. This standard does not replace good judgment and personal responsibility. In permitting use of the pool, spa, swim spa or portable spa by others, owners must consider the skill, attitude, training and experience of the expected user. As with any product, the specific recommendations for installation and use provided by the manufacturer should be carefully observed. This standard was prepared by the This standard was prepared by the APSP-7 Suction Entrapment Avoidance Standard Writing Committee of the Association of Pool and Spa Professionals (APSP) in accordance with American National Standards Institute (ANSI) Essential Requirements: Due process requirements for American National Standards. Consensus approval was achieved by a ballot of the balanced APSP Standards Consensus Committee and through an ANSI Public Review process. The ANSI Public Review provided an opportunity for additional input from industry, academia, regulatory agencies, safety experts, state code and health officials, and the public at large. Suggestions for improvement of this standard should be sent to The Association of Pool and Spa Professionals, 2111 Eisenhower Avenue, Alexandria, VA 22314. This standard is published in partnership with the International Code Council (ICC). ICC develops and publishes the International Building Code (IBC) and International Residential Code (IRC), which are adopted as the basis for the building codes used in most states and jurisdictions within the United States. Additionally, APSP and ICC have collaborated to develop the first comprehensive model swimming pool and spa code, known as the International Swimming Pool and Spa Code. This landmark document incorporates and references material from ANSI/APSP standards and ICC'S model codes, to create a stand-alone code that is consistent with codes and standards from both organizations. These codes and standards are the result of a joint effort between ICC and APSP as a service to both the swimming pool and spa community, and building code professionals. It is the hope of both organizations that they will lead to enhanced safety for pool and spa users around the world. III ©2013 The Association of Pool & Spa Professionals Licensed to Susan Ballard.

When used, SVRS and APSS devices shall be tested and certified by a third -party test lab accredited by the Interna- tional Laboratory Accreditation Cooperation (ILAC) to test and certify products as conforming to ASME/ ANSI A112.19.17, ASTM F 2387 or any successor standards recognized by the U.S. Consumer Product Safety Commission (CPSC). NOTE: As of the publication date of this standard, automatic pump shut-off systems do not have a per- formance standard to which they can be certified, as a result the U.S. Consumer Product Safety Commission (CPSC) states APSS are to be tested and certified in accordance with one of the SVRS standards. NOTICE: Operating conditions. Systems are tested for operation, in accordance with current standards, at room temperature. For substantially varying environ- mental conditions, including freezing, heat, salt spray, and humidity, confirm suitability with the SVRS manufacturer prior to installation and use. CAUTION: Incompatible configurations. Some suction vacuum release systems may be incompatible with certain system configurations. The designer or installer shall confirm suitability with the SVRS man- ufacturer prior to installation and use. Incompatible configurations may include check valves; two or more suction outlets, hydrostatic relief valves, skimmers, solar systems, elevated or submerged pump suction, multilevel bodies of water, and water features. 4.4 Performance requirements for suction outlets and suction -limiting systems NOTE: Suction -limiting systems protect against body entrapment but are not considered "backup" systems as there is no known suction -limiting system that will completely protect against the remaining four (eviscera- tion, limb, hair, mechanical) of the five known hazards and presenting suction -limiting systems as "backup" systems would promote a false sense of security among the users of these devices/systems. 4.4.1 Submerged suction outlets are optional. Fully submerged suction outlets (main drains) are not required in pools and spas. Surface skimming or overflow systems shall be permitted to provide 100 percent of the flow. 4.4.2 Field built sumps.

Downloaded 10/25/2021. Single user license only. Copying and networking prohibited. ANSI/APSP/ICC-7 2013 4.4.9 Maximum system flow rate. The maximum system flow rate shall be determined according to control system type where facilities with unsecured control systems use the options in 4.4.9.1 and facilities with secured control systems use the options in 4.4.9.2: 4.4.9.1 Maximum system flow rate -unsecured control systems. The maximum system flow rate is the pump's flow rate at the highest user selectable speed while the system is configured to operate at the lowest achievable system TDH when all flow is from the submerged suction system (skimmers off), the filter(s) is clean (when included), and all pressure -side valves are in the open (maximum flow) position. This operating point is determined by one of the following: • Measuring with flow meter accurate to ±10% and installed according to the manufacturers specification, or • Computing using complete system TDH calculations and then looking up the flow rate using the manufacturers certified pump curve, or • Measuring system TDH at the pump's drain plugs and then looking up the flow rate using the manufacturer's certified pump curve. 4.4.9.2 Maximum system flow rate -secured control systems. The maximum system flow rate is the flow rate for the pump at its highest operating speed with the lowest operating system resistance as defined by the Registered Design Professional. It applies to new or replacement pumps. Measure- ments shall be made with a properly sized flow meter accurate to f 10% and installed according to manufacturer's instructions. NOTE: The flow meter must be installed in accor- dance with the manufacturer's specific instruc- tions. Careful consideration must be given to pipe diameter and the required straight pipe distances between the flow meter and other fittings such as, but not limited to, elbows, tees, valves etc. No offset or estimation is to be allowed for flow meters that are not installed in accordance with the manufacturer's instructions. The manufacturer's claims must be NISTB traceable and verified by a third party. 4.5 Skimmers. Skimmers shall be vented to the atmos- phere through openings in the lid, or through a separate vent pipe (see Figure 7). 4.5.1 Skimmer equalizer lines. Skimmer equalizer lines shall not be used on new construction. Existing equalizer(s) shall comply with all submerged suction outlet requirements of this standard (see Figure 8). vent through lid Figure 7. Skimmer, vent through lid iiste suction outl( require Figure 8. Skimmer with equalizer 4.6 Wall vacuum fitting(s). When used, vacuum cleaner fitting(s) shall be located in an accessible position(s) no greater than 12 inches (305 ntni) below the water level and the self closing, self latching fitting shall comply with IAPMO SPS 4. In addition, the vacuum piping shall be equipped with a valve to remain in the closed position when not in use. NOTICE: SPS-4 requires tools to remove, but due to incompatible components, there have been multiple cases of removal upon each usage, sometimes resulting in loss of components, and the essential safety feature. Make sure that the attachment of a vacuum hose in normal usage never leads to removal of the self -closing self -latching feature. 5 New construction 5.1 General. Methods to avoid entrapment in circulation systems, swim jet systems, alternative suction systems, and debris removal systems are shown in Sections 5.2 through 5.5. 5.2 Submerged suction outlets are optional. See Section 4.4.1. 5.2.1 Wading Pools. Due to the unique hazard presented by submerged suction outlets in wading pools, submerged suction outlets are prohibited in wading pools in all areas accessible to the bather. 8.

Cop Waih@E"RI1U0i&9j4&pa Professionals Finding the Maximum Flow Rate of an Existing System Preparation: 1. Open all valves to their full open position for pool or spa circulation. (For secured systems, do not adjust valves.) 2. Remove eyeball fittings from return inlets (when removable by hand). 3. Clean skimmer and pump baskets. Turn off skimmer to isolate outlet, if possible. 4. Backwash or clean sand filter/DE grids, or remove cartridge. When inspecting existing installations, the maximum possible flow rate of suction system must be determined as explained in 4.4.9.*. Pump Method 1: Measure flow rate with a flow meter accurate to ±10% (see Section 4.4.9).* Pump Method 2: Calculate using pressure and vacuum gauge readings (see diagram below). 1. Install a vacuum gauge as close to the bottom of the strainer basket as possible. 2. Install a pressure gauge as close to the pump discharge as possible. NOTE: It may be necessary to use an NPT9 x barb fitting with a short section of plastic tubing connected to a gauge if gauges cannot be screwed into drain holes provided in pump. 3. Multiply vacuum reading by 1.13 and record. 4. Multiply pressure reading by 2.31 and record. 5. Add results of steps 3 and 4 together to get the approximate Total Dynamic Head (TDH) in feet of head. 6. Using the published curve for the pump, find the Total Dynamic Head calculated above on the vertical axis, and read the flow rate on the horizontal axis. 7. This will give you the maximum flow rate within approx. 10%. Pressure head: gauge psi x 2.31 = feet of water Suction head: gauge inches Hg x 1,13 = feet of water EXAMPLE: If the pressure gauge reads 14 psi and the vacuum gauge reads 6 inches of mercury (Hg), the approximate Total Dynamic Head (TDH) of the system would be 39.12 feet. hair �— 1 and PUMP lint trap Q� 14 psi f pressure gauge 6 in.
