How to fix STA-RITE Water Pump failure to pump water?

  If your STA-RITE Water Pump is not pumping water, has reduced capacity, or the discharge pressure is low, start by checking for suction leaks and ensuring the pump volute and strainer basket are full of water. Inspect the suction piping for leaks and make sure the suction pipe inlet is well below the water level to prevent the pump from sucking air. Also, verify the strainer pot/basket isn't clogged. Clean it if necessary. Check the voltage at the motor terminals and at the meter while the pump is running. Low voltage may indicate an electrical issue. Inspect for loose electrical connections. If the pump is trying to push water too high, consider using a higher head pump.

  If your STA-RITE Water Pump is too hot, check the line voltage. If it's less than 90% or more than 110% of the rated voltage, consult a licensed electrician. Increase ventilation to the pump, reduce the ambient temperature, and tighten any loose electrical connections.

  If your STA-RITE Water Pump isn't working properly due to a clogged pipe or impeller, or a worn impeller/diffuser, first ensure the strainer pot/basket is not clogged and clean it if needed. Then, check if the impeller is clogged. If you find a blockage, clear it. Inspect the impeller and diffuser for wear. If either shows signs of damage or major wear, order replacement parts.
