What to do if STA-RITE P2R5C-120L P2RA5C-119L Water Pump loses prime?
- D
  David Le MDAug 10, 2025
  If your STA-RITE Water Pump loses prime, it could be due to suction leaks. First, ensure the pump volute and trap are full. Check for any leaks in the suction piping. Make sure the suction pipe inlet is well below the water level to prevent the pump from sucking in air. If the suction trap gasket is defective, replace it. If the suction lift is too high (15 to 25 feet can reduce performance, and over 25 feet can prevent pumping), move the pump closer to the water source and ensure the suction pipe is large enough.

How to fix a clogged STA-RITE P2R5C-120L P2RA5C-119L?

  Ashley GarciaAug 22, 2025
  To fix a clogged STA-RITE Water Pump, start by checking the suction trap. If it's clogged, clean the trap and strainer. Also, the impeller might be clogged. If the pump is trying to push too high a column of water, a 'higher head' pump might be needed.

Why is my STA-RITE P2R5C-120L P2RA5C-119L Water Pump vibrating excessively?
- M
  Michael CruzAug 27, 2025
  Excessive vibration in your STA-RITE Water Pump can be due to inadequately supported suction and discharge piping. Also, avoid mounting the pump on a wooden platform; instead, securely mount it on a concrete platform for quieter performance.

What causes electrical issues in STA-RITE P2R5C-120L P2RA5C-119L Water Pump?
- A
  Ashley Frye MDSep 3, 2025
  Electrical issues in your STA-RITE Water Pump can stem from several causes. The pump might be running too slowly due to low voltage. Check the voltage at the motor terminals and at the meter while the pump is running and look for loose connections. Also, the pump may be overheating. Check the line voltage; if it's less than 90% or more than 110% of the rated voltage, consult a licensed electrician. Ensure there is adequate ventilation, reduce the ambient temperature, and tighten any loose connections.
