SYMPTOM
Pump / motor will not run
Motor runs hot and overload kicks off
Motor runs but no water is delivered
*(NOTE: Check prime before looking
for other causes. Unscrew priming plug
and see if there is water in priming hole)
Pump does not deliver water to full
capacity (also check point 3
immediately above)
Pump delivers water but will not shut off
Pressure switch turns on and off
every few seconds
POSSIBLE CAUSE
1. Disconnect switch is off
2. Fuse is blown
3. Starting switch is defective
4. Pressure switch contacts are dirty
5. Not enough water
6. Pump wire incorrectly
1. Motor is wired incorrectly
2. Voltage is too low
3. Pump cycles too frequently
1. Pump in a new installation did not
pick up prime through:*
a. Improper priming
b. Air leaks
c. Leaking foot valve
2. Pump has lost its prime through:*
a. Air leaks
b. Water level below suction of pump
3. Ejector or impeller plugged
4. Check valve or foot valve is stuck
in closed position
5. Pipes are frozen
6. Foot valve and/or strainer are buried
in sand or mud
1. Water level in well is lower than
estimated
2. Steel piping (if used) is corroded or
limed, causing excess friction
3. Offset piping is too small in size
1. Impeller neck is worn
2. Defective pressure switch
3. Tank precharge pressure is too high
1. Galvanized storage tank is waterlogged1. Replace
2. Leaky foot valve
3. Too much tank pressure

TROUBLESHOOTING CHART

CORRECTIVE ACTION
1. Be sure switch is on
2. Replace fuse
3. Disconnect power, replace
starting switch
4. Disconnect power and file
contacts with emery board
or nail file
5. Stop motor, remove pressure
gauge bushing, and fill case and
suction line with water
1. Refer to instructions on wiring
2. Check with power company.
Install heavier wiring if wire size is
too small. See wiring instructions
3. See section below on too frequent
cycling
1. In new installation:
a. Reprime according to
instructions
b. Check all connections on
suction line, air volume control
and ejector
c. Replace foot valve
2. In installation already in use:
a. Check all connections on air
suction line, volume control,
ejector and shaft seal
b. Lower suction line into water
and reprime. If receding water
level in a shallow well
operation exceeds suction lift,
a deep well pump is needed
3. Clean ejector or impeller
4. Replace check valve or foot valve
5. Thaw pipes. Bury pipes below
frost line. Heat pit or pump house
6. Raise foot valve and/or strainer
above well bottom.
1. A deep well jet may be needed
(over 25 ft. to water)
2. Replace with plastic pipe where
otherwise with new steel pipe
3. Use larger offset piping
1. Replace
2. Replace
3. Tank precharge pressure must be
1-2 pounds less than switch
cut in setting
2. Replace
3. Adjust to proper setting
