Troubleshooting
Problem
Probable Cause
Corrective Action
The motor will not run. The disconnect switch is off.
Ensure the switch is on.
The fuse is blown or circuit breaker tripped.
Replace the fuse or reset the circuit breaker.
The starting switch is defective.
DISCONNECT POWER; Replace the starting switch.
The wires at the motor are loose,
disconnected, or wired incorrectly.
Refer to the Wiring instructions. DISCONNECT POWER; check and
tighten all wiring.
The motor runs hot and
overload kicks off or
the motor does not run
and only hums.
The motor is wired incorrectly.
Refer to the Wiring instructions.
The voltage is too low.
Check with the power company. Install heavier wiring if the wire size
is too small (See the chart in the Wiring section).
The motor runs but no
water is delivered.
*Stop the pump; then
check the prime before
looking for other
causes. Unscrew the
priming plug and see if
water is in the priming
hole.
The pump was not primed correctly.
Re-prime according to instructions.
There are air leaks.
Check all connections on the suction line and shaft seal and AVC
with shaving cream.
The foot valve or check valve is leaking.
Replace the foot valve or check valve.
The pipe size is too small.
Re-pipe using the size of suction and discharge ports on the pump.
The water level is below the suction pipe
inlet.
Lower the suction line into the water and re-prime. If receding water
level in the well exceeds 25 ft. (7.6M), a deep well pump is needed.
The impeller is plugged.
Clean the impeller.
The check valve or foot valve is stuck shut.
Replace the check valve or foot valve.
The pipes are frozen.
Thaw pipes. Bury the pipes below the frost line. Heat pit or pump
house.
The foot valve and/or strainer are buried in
sand or mud.
Raise foot valve and/or strainer above bottom of water source.
The pump does not
deliver water to full
capacity.
The water level in the well is lower than
estimated.
A deep well jet will be needed if your well is more than 25 ft. (7.6M)
depth to water.
The steel piping (if used) is corroded or
limed, causing excess friction.
Replace with plastic pipe where possible, otherwise with new steel
pipe.
The piping is too small in size.
Use larger piping.
The pump is not being supplied with enough
water.
Add additional well points.
The pump leaks
around the clamp.
The clamp is loose.
STOP THE PUMP. Tighten the clamp nut 1-2 turns. Alternately
tighten and tap on the clamp with a mallet to seat the O-ring. Do not
overtighten.
