(A) Equipment required. Every private pool shall be equipped with a water recirculation system. The recirculation system shall consist of pumping equipment, a hair and lint catcher, rapid pressure filters, together with all necessary pipe connections to the pool inlets and outlets and for backwashing the filters, and equipment for disinfecting the pool water.
(B) Pump and filter capacity. The recirculation pump and filter tank and surface area shall be sufficient to achieve the minimum turnover, filtration and backwashing rates required by this chapter.
(C) Turnover period and filtration rate. There shall be 1 turnover of the entire contents of the pool every 12 hours or less at a filtration rate of not more than 3 gallons per square foot of filter area per minute.
(D) Hair and lint catcher. A hair and lint catcher shall be installed on the suction side of the recirculation pump to prevent hair, lint, and other extraneous matter from reaching the pump and filters. The hair and lint catcher shall be so designed that it can be easily dismantled for cleaning and inspection and shall be so located as to be easily accessible for cleaning.
(E) Filter backwashing and rate. The filters shall be backwashed at regular intervals at a minimum rate of 10 gallons per square foot of filter area per minute, or at the manufacturer’s recommended backwash flow rate, whichever is greater. The backwash cycle shall be continued until the backwash water is clear. All backwash water and effluents shall be discharged to the sewer through an indirect connection.
(F) Test kit. A test kit with permanent color standards shall be provided at every private pool and be used at frequent intervals to check on the adequacy of the chlorine treatment.
(G) Disinfection. 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 Building Director. 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) Chlorine. Gaseous chlorination systems shall not be made use of as a disinfection method for pool water.
