The recirculating pump shall have sufficient capacity to provide the rated flows of the filter system without exceeding the head loss at which the pump will deliver such flows. The pump motor shall not be operated at an overload which exceeds the service factor.
The pool pump shall be equipped on the inlet side with an approved-type hair and lint strainer, except for vacuum-type filters where water passes through the filter before reaching the pump. The basket of the strainer shall be noncorrosive and have an open screen surface of at least four times the cross-sectional area of the inlet pipe.
