Motor runs but no Pump in new installation did In new installation:
water is delivered* not pick up prime through:
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 soapy water.
2. Water level below 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 Raise foot valve and/or strainer above bottom of water source.
