POSSIBLE CAUSE(S)
Motor will not run
Fuse is blown or circuit breaker tripped
Motor runs hot and
Voltage is too low
the overload kicks
off or the does not
run and only hums.
Motor runs but no
Pump during new installation did
water is delivered*
not pick up prime through:
1. Improper priming
2. Air leaks
* (Note: Stop pump;
then check prime
3. Leaking foot valve
before looking
for other causes.
4. Pipe size is too small
Unscrew priming plug
Pump has lost prime through:
and see if water is in
1. Air leaks
priming hole).
2. Water level below suction pipe inlet
Impeller is plugged
Foot valve is stuck shut
Pipes are frozen
Foot valve and/or strainer are
buried in sand or mud
*Pump does not
Water being pumped is lower than
deliver water to full
estimated

Steel piping (if used) is corroded or
limed, causing excess friction
Piping is too small in size
Pump not being supplied with

CORRECTIVE ACTION
DISCONNECT POWER; Replace fuse or reset circuit breaker.
Check voltage being supplied to the 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 size 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 receding water level
in well exceeds 25' (7.6M), a deep well pump is needed.
Clean impeller.
Replace the foot valve.
Thaw pipes.
Raise the foot valve and/or strainer above bottom of water source.
Clean foot valve and strainer.
A deep well jet will may needed if the water being pumped is more than
25' (7.6M) depth to water.
Replace with plastic pipe where possible, otherwise with new steel pipe.
Re-pipe using size of suction and discharge ports on pump.
Add additional well points.
