overload kicks off
Voltage is too low Check with power company. Install heavier wiring if wire size is too small
(See Electrical / Wiring Chart).
Pump cycles too frequently See section below on too frequent cycling
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
3. Leaking foot valve or check valve 3. Replace foot valve or check valve
Pump has lost prime through: In installation already in use:
1. Air leaks 1. Check all connections on suction line and shaft seal
2. Water level below suction pipe inlet 2. Lower suction line into water and re-prime. If water level in well
exceeds 20 feet, a deep well pump is needed.
Foot valve or strainer is plugged Clean foot valve or strainer
Ejector or 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.
buried in sand or mud Clean foot valve and strainer.
Water level is too low for centrifugal A deep well jet pump and package may be needed (over 20 ft. to water) to
setup to deliver water deliver water to full capacity
Pump does not Water level in deep well is lower than A deep well jet pump and package may be needed (over 20 ft. to water) to

capacity
Steel piping (if used) is corroded or Replace with plastic pipe where possible, otherwise with new steel pipe
limed, causing excess friction
Piping is too small in size Use larger piping
Air leak in suction line Check all connections, inspect line for cracks (test with soapy water while
pump is running - a leak will pull soap suds into hole)
Need more driven points Add driven points to suction line until performance in O.K.
