3.4 Pump Strainer Basket
This pump has a basket strainer, sometimes called a “Hair and Lint Pot” located in the front section of the pump
volute. Inside this chamber is a basket which must be kept clean of leaves and debris at all times. View the
basket through the “See-Through Lid” to inspect for various accumulations of trash. Regardless of the length of
time between filter cleaning, it is most important to visually inspect the basket at least once a week. A dirty
basket will reduce the efficiency of the filter and also put an abnormal stress on the pump motor which could
result in failure.
Warning:
Do not open the strainer pot if the pump fails to prime or if the pump has been operating
without water in the strainer pot. Pumps operated in these circumstances may experience a buildup
of vapor pressure and may contain scalding hot water. Opening the pump may cause serious
personal injury. In order to avoid the possibility of personal injury, make sure the suction and
discharge valves are open and strainer pot temperature is cool to the touch, then with extreme
caution, you can open the strainer lid. Do not open the strainer pot lid while the pump in in
operation.
