(a) Pump. A removable and reinstallable pump(s) shall be installed with adequate capacity for the required turnover time specified in Section 838.33(b). Whenever possible, pump(s) shall be so located as to eliminate the need for priming. If the pump(s) or suction piping is located above the overflow level of the swimming pool, the pump(s) shall be self-priming. Pumps shall be securely supported. Pumping equipment shall have sufficient capacity to discharge the volume of water for the required turnover of the pool against the maximum head in the recirculation system. The pump used for backwashing sand filters shall have sufficient capacity to backwash the unit at the rate of at least 12 gallons per minute per square foot of filter area against the maximum head developed during backwashing.
(b) Hair and lint strainer. All pressure filter systems shall have a hair and lint strainer installed ahead of the filter pump. The hair and lint strainer baskets shall be corrosion resistant with openings not exceeding one-eighth inch in size, which provide a free flow area of at least four times the area of the pump suction line at the strainer connection, and shall be accessible for frequent cleaning. An extra hair and lint strainer basket shall be provided for each hair and lint strainer.
