  If your Pentair Water Pump motor won't run, start by ensuring the disconnect switch is turned on. If it still doesn't work, check the fuse and replace it if it's blown, or reset the circuit breaker if it has tripped. Also, inspect the wires at the motor to ensure they are tightly connected and wired correctly. If these steps don't resolve the issue, the starting switch might be defective and need replacement.

Why does my Pentair FLOTEC FP4212 deliver water but not shut off or pump cycles too frequently?

  Several factors can cause a Pentair Water Pump to not shut off or cycle too frequently. Begin by checking if any faucets have been left open and close them. Next, examine the pressure switch; it may be out of adjustment or its contacts might be welded together, requiring adjustment or replacement. Also, inspect the venturi, nozzle, or impeller for clogs and clean them if necessary. A waterlogged standard pressure tank without an air cushion could also be the cause; drain the tank to the air volume control port. Check for leaks in pipes and foot valves, and ensure the air charge in the pre-charged tank is adequate using a tire pressure gauge.

What to do if my Pentair FLOTEC FP4212 motor runs hot and overload kicks off?

  If your Pentair Water Pump motor runs hot and the overload kicks off, it could be due to incorrect wiring. Refer to the wiring instructions to ensure it's properly connected. Low voltage can also cause this issue, so check with your power company. If the pump cycles too frequently, installing heavier wiring may be necessary, referring to the Electrical / Wiring Chart for guidance.

Why does my Pentair FLOTEC FP4212 have air spurts from faucets?
- A
  Amy FranklinAug 29, 2025
  If you're experiencing air spurts from the faucets with your Pentair Water Pump, it could be due to several reasons. The well might be gaseous, in which case you should consult the factory about installing a sleeve in the well. Another possibility is a leak in the suction side of the pump; check the joints for leaks using shaving cream. The pump might also be picking up prime; once it does, it should pump solid water without air. Intermittent over-pumping of the well can also cause this; lower the foot valve if possible, or restrict the pump discharge.

Why Pentair FLOTEC FP4212 Water Pump does not deliver water to full capacity?
- J
  Jeffrey WatersSep 4, 2025
  If your Pentair Water Pump isn't delivering water to its full capacity, it could be due to corroded or limed steel piping, causing excess friction; replace with plastic pipe where possible, or with new steel pipe. Also, ensure that the piping isn't too small in size; use larger piping if necessary.

  If the Pentair Water Pump motor runs but no water is delivered, consider these possibilities: * If it's a new installation, re-prime the pump according to instructions. * Check all connections on the suction line, AVC, and ejector for leaks using soapy water or shaving cream. * Inspect the foot valve or check valve for leaks and replace if necessary. * Clean the foot valve or strainer if plugged. * Clean the ejector or impeller if they are plugged. * Replace the check valve or foot valve if stuck shut. * Thaw pipes if frozen. * Raise the foot valve and/or strainer above the bottom of the water source if buried in sand or mud. * If using a shallow well setup, a deep well jet may be needed if the water depth is more than 25’ (7.6M). * Lower the suction line into the water...
