(a) Private residential swimming pool water recirculation system inlet shall be located so as to produce so far as possible uniform circulation of water throughout the pool without the existence of dead spots and to carry pool bottom deposits to the outlets. Recirculation systems inlets in the pool walls shall be spaced not more than 20 feet on centers entirely around the perimeter of the pool and shall discharge at a minimum depth of ten inches below the pool overflow level.
(b) Pools shall be equipped with suitable facilities for adding make-up water as needed. There shall be no physical connection between the water supply line and the pool system. If the make-up water is added directly to the pool, the outlet shall be at least six inches above the upper rim of the pool. If the make-up water line discharges to a surge or balancing tank, the point of discharge shall be at least six inches above the rim of the tank. If a hose connection from a sill cock or other plumbing fixture is to be used for supplying make-up water then an approved vacuum breaker shall be installed between the sill cock or control valve at the fixture and the hose connection. The vacuum breaker shall be installed at a height not less than seven feet six inches above the floor, platform or ground upon which a person would stand when operating the sill cock or control valve.
(c) The systems supplying recirculated water and make-up water to the pool shall be constructed in conformance with Chapter 18-29 of this Code.
(Prior code § 61-18.13; Amend Coun. J. 11-9-16, p. 36266, § 20)
(a) Private residential swimming pool water recirculation system outlets should be so located as to provide at least one outlet at the deepest point in the pool if the pool width does not exceed 20 feet. If the pool width is more than 20 feet, multiple outlets shall be provided and spaced not more than 20 feet apart, nor more than ten feet from walls. All pool drain outlets shall be equipped with gratings having an area of openings not less than ten times the cross-sectional area of the outlet pipe. The gratings shall be of such design so as they can not be readily removable by bathers and will not injure bathers' fingers.
(b) Pools shall be equipped with facilities for completely emptying the pool and the discharge of the pool water to the sewer shall be at a rate not exceeding 250 gallons per minute. No direct connection shall be made to the sewer. The drainage system shall be constructed in conformance with the provisions of Chapter 18-29 of this Code. The drain pipe line diameter shall be at least six inches.
(c) Drain pipe lines from walk areas, scum gutters and pools shall discharge into a common catchbasin. If elevation permits, the catchbasin may drain by gravity into the sewer. If, however, the elevations are such as to require pumping, the combined discharge shall be pumped into the sewer. In either case, a backwater valve or gate shall be installed downstream from the catchbasin and the pump. Water drained from the pool shall not be discharged to the sewer system during periods of rain or storms. At no time shall the rate of drain water discharge exceed a flow of 250 gallons per minute.
(Prior code § 61-18.14; Amend Coun. J. 11-9-16, p. 36266, § 20)
(a) Private residential swimming pools recirculation systems shall consist of pumping equipment, hair and lint catchers, filters together with the necessary pipe connections to the pool inlets and outlets, facilities and pipe connections necessary for backwashing filters, and facilities and equipment for disinfecting the pool water.
(b) The entire recirculating system shall be capable of producing a six-hour turnover of the entire water volume contents.
(c) The recirculation system pump shall have sufficient capacity to discharge the volume of water required for a six-hour turnover of the pool against the maximum head in the recirculating system.
(d) The pump used for backwashing filters shall have sufficient capacity to provide a filter backwash rate of at least 15 gallons per minute per square foot of filter area.
(e) A hair and lint catcher or strainer shall be installed on the suction side of the circulation pump to prevent hair, lint and other extraneous matter from reaching the pump and filters. Hair and lint catchers shall be so designed that they can be easily dismantled for cleaning and inspection and shall be so located as to be easily accessible for cleaning. The design features shall be as follows: Water passes through the strainer from the outside; the strainer is made of noncorrosive material; the width or diameter of strainer openings is not more than one-eighth inch; the area of the strainer openings shall be at least five times the cross-sectional area of the inlet pipe to the strainer.
(f) Recirculating systems shall contain rapid pressure filters. Sufficient filter area shall be provided to filter the entire contents of the pool in six hours at the rate of not more than three gallons per square foot of filter area per minute. The filter backwashing facilities shall be sufficient to backwash at the rate of 15 gallons per minute per square foot of filter area. All backwash water and effluents shall be discharged to the sewer through an indirect connection. Pressure filters shall be equipped with readily accessible air relief valves, loss of head or pressure gauges on the inlet and outlet pipes, and an access head or hole large enough to permit inspection, maintenance and repair work. Sight glasses that can be easily removed for cleaning shall be provided in the effluent line from the filter units.
(g) Equipment shall be provided for the disinfection of all pool water. Any disinfection method using materials other than chlorine compounds shall be subject to the approval of the board of health. Disinfection equipment installed for the use of chlorine compounds shall have sufficient capacity to maintain a minimum free chlorine residual of 0.5 parts per million. The disinfectant shall be introduced into the recirculation system ahead of the filters.
(h) Gaseous chlorination systems shall not be made use of as a disinfection method for pool water.
(Prior code § 61-18.15)
All electrical installations provided for, installed and used in conjunction with private residential swimming pools, shall be in conformance with Title 14E.
