CORRECTIVE ACTION
DISCONNECT POWER; Replace fuse or reset circuit breaker
Check voltage being supplied to pump
In new installation:
1. Re-prime according to instructions
2. Check all connections on suction line, with soapy water or
shaving cream
3. Replace foot valve
4. Re-pipe using pipe the same size as of suction and discharge
ports on pump
In installation already in use:
1. Check all connections on suction line and shaft seal with soapy water.
2. Lower suction line into water and re-prime. If the water level is more
than 25' (7.6M) below the pump, a deep well pump is needed
Clean impeller
Replace the foot valve
Thaw pipes
Raise foot valve and/or strainer above bottom of water source
Clean foot valve and strainer
A deep well jet will be needed if your well is more than 25' (7.6M)
depth to water
Replace with plastic or new steel pipe
Re-pipe using pipe the same size as suction and discharge ports on pump
Inlet pipe is too small
