Solution
Pump must be primed; make sure that pump volute and trap are full of water. See Priming Pump.
Make sure there are no leaks in suction piping.
Make sure suction pipe inlet is well below the water level to prevent pump from sucking air.
If suction trap gasket is defective, replace it.
Make sure pump is not trying to lift water more than 10' (3m).
Make sure suction pipe is at least 1-1/2" (38mm) in diameter.
Make sure suction trap is not clogged; if it is, clean trap and strainer.
Make sure impeller is not clogged (follow instructions in Removing Old Seal; check impeller for clogging; follow
instructions in Installing New Seal for reassembly).
Impeller and diffuser may be worn. If so, order replacement parts. See Repair Parts.
Check voltage at motor terminals and at meter while pump is running. If low, see wiring instructions or consult power
company. Check for loose connections.
Check line voltage; if less than 90% or more than 110% of rated voltage consult a licensed electrician.
Increase ventilation.
Reduce ambient temperature.
Tighten any loose connections.
If suction and discharge piping are not adequately supported, pump assembly will be strained. See Installation.
Do not mount pump on a wooden platform! Securely mount on concrete platform for quietest performance.
