Why is my Pentair Water Pump having reduced capacity?
- ZzalexanderAug 2, 2025
If your Pentair Water Pump is experiencing reduced capacity and/or head, check for air pockets or leaks in the suction line by inspecting the suction piping and valve glands on any suction gate valves. Also, the impeller might be clogged. To resolve this, turn off the electrical power to the pump, remove the six bolts holding the volute to the seal plate, slide the motor and seal plate away from the volute, and then clean any debris from the impeller. Another possible reason - clogged pump strainer. Clean suction trap.
