PROBLEM
Little or no
1. Pump is not primed
discharge
2. Suction lift too high or too long
3. Hole or air leak in suction line
4. Foot valve too small
5. Foot valve or suction line not
submerged deep enough in water
6. Voltage switch incorrect
7. Casing gasket leaking
Pump will not
1. Pump is not primed
deliver water
2. Leak in suction line
or develop
pressure
3. Discharge line is closed and priming
air has nowhere to go
4. Foot valve is leaking
5. Foot valve not submerged below
water level
Pump vibrates
1. Mounting plate or foundation not rigid
and/or makes
enough
excessive
2. Foreign material in pump
noise
3. Impeller damaged
Pump will not
1. Voltage switch incorrect
start or run
2. Blown fuse or open circuit breaker
3. Loose or broken wiring
4. Stone or foreign object lodged in
impeller
5. Thermal overload has opened circuit
POSSIBLE CAUSE
CORRECTIVE ACTION
1. Follow priming instructions (page 13)
2. Move pump closer to water source.
Lift should be less than 25 ft.
3. Repair or replace. Use pipe tape and
pipe sealing compound
4. Match foot valve to piping or install
one size larger foot valve
5. Submerge lower in water
6. Be sure 115 V or 230 V power supply
matches voltage switch setting on
pump (A)
7. Replace
1. Follow priming instructions (page 13)
2. Repair or replace. Pipe dope all
threads
3. Open several outlets or faucets
during priming procedure
4. Replace foot valve
5. Lower foot valve and reprime
1. Reinforce
2. Disassemble pump and clean
3. Replace
1. Be sure 115 V or 230 V power supply
matches voltage switch setting on
motor
2. Replace fuse or close circuit breaker
3. Tighten connections, replace broken
wiring
4. Disassemble pump and remove
foreign object
5. Allow unit to cool, restart after reason
for overload has been determined
