  Tyrone SmithJul 28, 2025
  If your Pentair Water Pump isn't priming, it could be due to a few reasons. First, there might be an air leak in the suction. Inspect the suction piping and valve glands on any suction gate valves. Another reason could be insufficient water; ensure the water level is high enough so the skimmer isn't drawing air. Lastly, the pump strainer basket might be clogged, so clean the pump strainer pot.

  If your Pentair Water Pump has reduced capacity, several factors could be responsible. Check for air pockets or leaks in the suction line by inspecting the suction piping and valve glands on any suction gate valves. A clogged impeller can also cause this issue; clean any debris from the impeller. Additionally, a clogged pump strainer pot can restrict flow, so clean the pump strainer pot.

  Inadequate circulation in your Pentair Water Pump system can stem from a few causes. A dirty filter or pump basket can restrict flow; check the trap basket, and if it's plugged, turn the pump off and clean the basket. Insufficient piping size can also be a factor, so consider increasing the piping size. Also, ensure that the speed is not set too slow for proper filtration cycle, so increase filtration run time.

  Gregory EvansAug 17, 2025
  If your Pentair Water Pump isn't responding to IntelliTouch, EasyTouch, SunTouch, or IntelliComm system commands, it might be due to improper automation setup. Ensure that the communication cable is securely connected at both ends. It could also be due to a communication network inoperative, a defective device on the network can inhibit the proper operation of other network device.
