  If your Pentair Water Pump motor isn't running, there could be several reasons. First, ensure the disconnect switch is turned on. If it is on, check the fuse and replace it if it's blown. A defective starting switch could also be the culprit, in which case it should be replaced. Lastly, inspect the wiring at the motor for looseness, disconnections, or incorrect wiring. Refer to the wiring instructions to correct any issues. Remember that capacitor voltage can be hazardous, so discharge the capacitor with an insulated screwdriver if necessary, or consult a qualified electrician.

Why does my Pentair BERKELEY 10LTHH3 Water Pump motor run hot and overload kicks off?

  If your Pentair Water Pump motor runs hot and the overload protection activates, it could be due to incorrect wiring. Refer to the wiring instructions to ensure it's properly connected. Another possibility is low voltage. Contact your power company to check the voltage, and if the wire size is too small, install heavier wiring, referring to the electrical section of this manual for guidance.

How to fix Pentair BERKELEY 10LTHH3 Water Pump that does not deliver water to full capacity?

  If your Pentair Water Pump isn't delivering water to its full capacity, a few things could be the cause. A leaking foot valve might be causing a loss of priming, in which case you should replace the foot valve. If the water level in your well is more than 25 feet below the pump's suction point, you might need a deep well jet pump. Also, if you're using steel piping, corrosion or lime buildup could be creating excess friction; consider replacing it with plastic pipe where possible, or with new steel pipe. Finally, check if the offset piping is too small and replace it with larger diameter piping.

  If your Pentair Water Pump isn't delivering water to its full capacity, consider the following: * The water level in the well might be lower than estimated. If the water level is more than 20 ft. deep, a deep well jet pump may be necessary. * Steel piping (if used) could be corroded or limed, causing excess friction. Replace it with plastic pipe where possible, or with new steel pipe. * Offset piping might be too small. Use larger offset piping.

  If your Pentair Water Pump motor runs hot and the overload trips, the issue might be due to incorrect wiring. Refer to the wiring instructions to ensure it's properly connected. Another potential cause is low voltage. Check with your power company and consider installing heavier wiring if the current wire size is too small.

What to do if Pentair Water Pump motor runs but no water is delivered?

  Thomas SmithNov 11, 2025
  If your Pentair Water Pump motor runs but no water is being delivered, several factors could be at play. If it's a new installation, the pump might not have picked up prime due to improper priming, air leaks, or a leaking foot valve. Re-prime the pump according to the instructions, check all connections on the suction line, and replace the foot valve if needed. If the pump has lost prime in an existing installation, check for air leaks in the suction line and shaft seal, and ensure the water level hasn't dropped below the suction point. Lower the suction line into the water and re-prime the pump. Also, the impeller could be plugged, so clean it following the impeller cleaning procedures. Other potential issues include a stuck check valve or foot valve (replace if necessary), frozen pipes (...

  If your Pentair Water Pump motor runs but doesn't deliver water, first check the prime by unscrewing the priming plug to see if there's water in the priming hole. If the pump isn't primed, consider these potential causes: For new installations: * Improper priming: Re-prime the pump according to the instructions. * Air leaks: Check all connections on the suction line. * Leaking foot valve: Replace the foot valve. For installations already in use: * Air leaks: Check all connections on the suction line and shaft seal. * Water level below suction of pump: Lower the suction line into the water and re-prime. Other potential issues: * Plugged impeller: Clean the impeller, following the maintenance instructions. * Stuck check valve or foot valve: Replace the check valve or foot...
