TROUBLESHOOTING
CORRECTIVE ACTION
Be sure switch is on.
Replace fuse or reset circuit breaker.
DISCONNECT POWER; Replace starting switch.
Refer to instructions on wiring (Page 7). 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.
Clean foot valve and strainer.
A deep well jet will be needed if your well 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.
