capacitor terminals together. Do not touch metal screwdriver blade or capacitor terminals. If in doubt, consult a qualified electrician.
Symptom Possible Cause(s)
Motor will not run Disconnect switch is off.
Fuse is blown or circuit breaker tripped
Starting switch is defective.
Wire ast motor are loose, disconnected, or wired
incorrectly.
Motor runs hot and Motor is wired incorrectly
overload kicks off or
Voltage is too low.
motor does not run and
only hums.
Motor Runs but no water Pump in new installation did not pick up prime
is delivered* through:
1. Improper priming
2. Air leaks.
*(Note: Stop pump;
then check prime before 3. Leaking foot valve or check valve
looking for other causes.
4. Pipe size too small
Unscrew priming plug
Pump has lost prime through:
and see if water is in
priming hole).
1. Air leaks
2. Water level bellow suction pipe inlet.
Impeller is plugged
Check valve or foot valve is stuck shut
Pipes are frozen
Foot valve and/or strainer are buried in sand or mud
*Pump does not deliver Water level in well is lower than estimated
water to full capacity.
Steel piping (if used) is corroded or limed, causing
excess friction
Piping is too small in size
Pump not being supplied with enough water
Pump leaks around Clamp loose

Corrective Action
Be sure switch is on.
Replace fuse or reset breaker.
DISCONNECT POWER; Replace starting switch.
Refer to instructions on wiring. DISCONNECT POWER; check and tighten
all wiring.
Refer to instructions on wiring.
Check voltage being supplied to motor. Install heavier wiring if wire size is
too small (See Electrical / Wiring Chart)
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 or check 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 check valve or foot valve
Thaw pipes. Bury pipes below frost line. Heat pit or pump house.
Raise foot valve and/or strainer above bottom of water source.
A deep well jet will be needed if your well is more than 25' (7.6M) dept 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.
STOP PUMP, tighten clamp nut 1 - 2 turns. Alternately tighten and tap on
clamp with mallet to seat O-Ring. Do not overtighten.
