Risk of electric shock. Electricity can shock, burn or kill. To discharge capacitor, hold insulated
handle screwdriver BY THE HANDLE and short capacitor terminals together. Do not touch metal screwdriver blade or
capacitor
terminals. If in doubt, consult a qualified electrician.
TROUBLE SHOOTING
SYSTEM
Motor will not run
Motor runs hot and
overload kicks off or motor
does not run and only
hums.
Motor runs but no
water is delivered*
*Stop pump; then check
prime before looking for
other causes. Unscrew
priming plug and see if
water is in priming hole
Pump does not deliver
water to full capacity.
Pump leaks around clamp
!
POSSIBLE CAUSE(S)
Disconnect switch is off
Fuse is blown or circuit breaker tripped
Starting switch is defective
Wires at motor are loose, disconnected, or wired
incorrectly
Motor is wired incorrectly
Voltage is too low
Pump in new installation did
not pick up prime through:
1. Improper priming
2. Air leaks
3. Leaking foot valve or check valve
4. Pipe size too small
Pump has lost prime through:
1. Air leaks
2. Water level below 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
Water level in well is lower than estimated.
Steel piping (if used) is corroded or limed, causing
excess friction
Piping is too small in size
Pump not being supplied with enough water
Clamp loose
CORRECTIVE ACTION
Be sure switch is on.
Replace fuse or reset circuit breaker.
DISCONNECT POWER; Replace starting switch
Refer to instructions on wiring. DISCONNECT POWER; check and tighten all
wiring.
Refer to instructions on wiring. Install heavier wiring if wire size is too small
(See Electrical/Wiring Chart) instructions on wiring.
Check with power company.
In new installation:
1. Re-prime according to instructions.
2. Check all connections on suction line and AVC with shaving cream.
3. Replace foot valve or check valve.
4. Re-pipe using size of suction and discharge ports on pump.
1. Check all connections on suction line and shaft seal.
2. Lower suction line into water and re-prime. If receding water level in
well exceeds 20’ (7.6M0, 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 20’ (6.1M) depth to
water.
Replace with plastic pipe where possible, otherwise with new steel pipe.
Use larger piping.
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.
