(a) Spa pool inlets and outlets shall be provided and arranged to maintain a uniform circulation of water and disinfectant residual.
(b) All spa pool piping shall comply with the requirements specified in Section 838.37, except only subsurface spa pool piping which is not integrally included in the manufacture of the spa pool shall be embedded in and covered with sand or an approved equivalent.
(c) All spa pools shall be provided with a minimum of one skimmer. Spa pool skimmers shall comply with the requirements specified in Section 838.41(b).
(d) Spa pool suction outlets shall be designed so that each pumping system in the spa pool provides one of the following alternatives:
(1) Two or more interconnected suction outlets. The system shall be designed so that none of the outlets can be isolated from the suction line by a valve or by any other means. All piping associated with the suction outlets shall be of equal diameter and each suction outlet shall be of equal size. Suction outlets and associated piping shall be hydraulically designed to provide equal flow through each suction outlet. The open area of the suction outlets shall be covered with suitable protective grates or covers that are anchored using manufacturer supplied parts in strict accordance with the manufacturer's specifications and recommendations and shall be designed to prevent body entrapment or injury. The suction outlet covers shall be secured so that their removal requires the use of tools. Suction outlet covers shall be manufactured and installed according to the latest specifications set forth by the ASME/ANSI and NSF International standards for suction fittings. The cover, frame and all components shall be corrosion resistant and shall be designed to withstand the maximum anticipated forces generated by active use. If the suction outlets are main drain outlets, they shall have antivortex covers or grates, shall be located in the deepest part of the spa pool, and shall be capable of draining the pool. The total water velocity through suction outlets, with the exception of skimmers, shall not exceed one foot per second and shall not exceed the maximum flow rate specified by the manufacturer of the suction outlet cover.
(2) Other methods that prevent suction outlet body entrapment or injury may be approved by the Director.
(e) If fill spouts are used at spa pools, they shall be installed according to applicable requirements specified in Section 838.37(b).
