Symptom Possible Cause(s) Corrective Action
Motor will not run Disconnect switch is off. Be sure switch is on.
Fuse is blown or circuit breaker tripped Replace fuse or reset breaker.
Starting switch is defective. DISCONNECT POWER; Replace starting switch.
Wire ast motor are loose, disconnected, or wired
incorrectly.
Refer to instructions on wiring. DISCONNECT POWER; check and tighten
all wiring.
Motor runs hot and
overload kicks off or
motor does not run and
only hums.
Motor is wired incorrectly Refer to instructions on wiring.
Voltage is too low. Check voltage being supplied to motor. Install heavier wiring if wire size is
too small (See Electrical / Wiring Chart)
Motor Runs but no water
is delivered*
*(Note: Stop pump;
then check prime before
looking for other causes.
Unscrew priming plug
and see if water is in
priming hole).
Pump in new installation did not pick up prime
through:
In new installation:
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 or check valve 3. Replace foot valve or check valve.
4. Pipe size too small 4. Re-pipe using size 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 soapywater.
2. Water level bellow suction pipe inlet. 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.
Impeller is plugged Clean impeller
Check valve or foot valve is stuck shut Replace check valve or foot valve
Pipes are frozen Thaw pipes. Bury pipes below frost line. Heat pit or pump house.
Foot valve and/or strainer are buried in sand or mud Raise foot valve and/or strainer above bottom of water source.
*Pump does not deliver
water to full capacity.
Water level in well is lower than estimated A deep well jet will be needed if your well is more than 25’ (7.6M) dept to
water.
Steel piping (if used) is corroded or limed, causing
excess friction
Replace with plastic pipe where possible, otherwise with new steel pipe.
Piping is too small in size Re-pipe using size of suction and discharge ports on pump
Pump not being supplied with enough water Add additional well points.
Pump leaks around
clamp
Clamp loose STOP PUMP, tighten clamp nut 1 - 2 turns. Alternately tighten and tap on
clamp with mallet to seat O-Ring. Do not overtighten.
