TROUBLESHOOTING
* (Note: Stop pump;
then check prime
before looking for
other causes.
Unscrew priming
plug and see if water
is in priming hole).
SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Motor will not run Fuse is blown or circuit breaker tripped DISCONNECT POWER; Replace fuse or reset circuit breaker
Motor runs hot and Voltage is too low Check voltage being supplied to pump
overload kicks off or
motor does not run
and only hums
Motor runs but no Pump during new installation did In new installation:
water is delivered* not pick up prime through:
1. Improper priming 1. Re-prime according to instructions
2. Air leaks 2. Check all connections on suction line, with soapy water or
shaving cream
3. Leaking foot valve 3. Replace foot valve
4. Pipe size too small 4. Re-pipe using pipe the same size as of suction and discharge
ports on pump
Pump has lost prime through: In installation already in use:
1. Air leaks 1. Check all connections on suction line and shaft seal with soapy water.
2. Water level below suction pipe inlet 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
Impeller is plugged Clean impeller
Foot valve is stuck shut Replace the foot valve
Pipes are frozen Thaw pipes
Foot valve and/or strainer are Raise foot valve and/or strainer above bottom of water source
buried in sand or mud Clean foot valve and strainer
*Pump does not Water being pumped is lower than A deep well jet will be needed if your well is more than 25’ (7.6M)
deliver water to full estimated depth to water
capacity
Corroded pipes or hoses Replace with plastic or new steel pipe
Piping is too small in size Re-pipe using pipe the same size as suction and discharge ports on pump
Pump not being supplied with Inlet pipe is too small
enough water
