FAILURE TO PUMP

REDUCED CAPACITY OR
DISCHARGE PRESSURE

Suction leaks/lost prime:

• Pump must be primed; make sure that pump volute
  and trap are full of water.
• 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 2" (51mm) in
  diameter.

Clogged pipe/trap/impeller, worn impeller:

• Make sure suction trap is not clogged; if it is, clean
  trap and strainer.
• Make sure impeller is not clogged
• Impeller and diffuser may be worn. If so, order
  replacement parts from Repair Parts List
