TROUBLE
POSSIBLE CAUSES
Motor will not run
1. Disconnect switch is off
2. Fuse is blown
3. Starting switch is defective
4. Wires at motor are loose,
*5. Motor is wired incorrectly
6. Pressure switch contacts are dirty
Motor runs hot and
*1. Motor is wired incorrectly
overload kicks off
2. Voltage is too low
3. Pump cycles too frequently
Motor runs but no
*1. Pump in a new installation did
water is delivered
(*Note: Check
prime before look-
*2. Pump has lost its prime through:
ing for other
causes. Unscrew
priming plug and
see if there is water
3. Jet or impeller is plugged
in priming hole)
4. Check valve or foot valve is stuck
5. Pipes are frozen
6. Foot valve and/or strainer are
Pump does not
1. Water level in well is lower than
deliver water to full
capacity (also check
2. Steel piping (if used) is corroded or
point 3 immediately
above)
3. Offset piping is too small in size
Pump pumps water
1. Pressure switch is out of adjustment
but does not shut off
2. Faucets have been left open
3. Jet or impeller is clogged
*4. Motor is wired incorrectly
5. Water level in well is lower than
Pump cycles too
1. Pipes leak
frequently
2. Faucets or valves are open
3. Foot valve leaks
4. Pressure switch is out of adjustment
5. Air charge too low in
Air spurts from
1. Pump is picking up prime
faucets
2. Leak in suction side of pump
3. Well is gaseous
4. Intermittent over-pumping of well
Leaks at the metal
1. Loose clamps or "O" ring
clamp
Release all pressure
in system before
working on clamp!
TROUBLESHOOTING GUIDE
disconnected, or wired incorrectly
not pick up prime through:
a. Improper priming
b. Air leaks
c. Leaking foot valve
a. Air leaks
b. Water level below suction of pump
in closed position
buried in sand or mud
estimated
limed, causing excess friction
or contacts are "frozen"
estimated
Captive Air® Tank
not sealed
REMEDIES
1. Be sure switch is on
2. Replace fuse
3. Replace starting switch
4. Refer to instructions on wiring
5. Refer to instructions on wiring
6. Clean by sliding piece of plain paper between contacts
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. Re-prime according to instructions
b. Check all connections on suction line and jet
c. Replace foot valve
2. In installation already in use:
a. Check all connections on suction line, jet and shaft seal
b. Lower suction line into water and re-prime. If receding
water level in a shallow well operation exceeds
suction lift, a deep well pump is needed
3. Clean jet or impeller according to instructions
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 pump may be needed (over 20 ft. to water)
2. Replace with Plastic Pipe where possible, otherwise with
new steel pipe
3. Use larger offset piping
1. Adjust or replace pressure switch
2. Close faucets
3. Clean jet or impeller
4. Refer to instructions on wiring
5. Check possibility of using a deep well jet pump
1. Check connections, replace pipe fittings
2. Close faucets or valves
3. Replace foot valve
4. Adjust or replace pressure switch
5. Disconnect electrical power and open faucets until all
pressure is relieved. Using automobile tire pressure
gauge, check air pressure in tank at the valve stem
located at top of tank. If less than 30 pounds, pump air
into tank from outside source, until 30 pounds pressure
is reached. Check air valve for leaks, using soapy
solution, and replace core if necessary
1. As soon as pump picks up prime, all air will be ejected
2. Check suction piping, make sure joints are not sucking air
3. Change installation as described in manual
4. Lower foot valve if possible, otherwise restrict discharge
side of pump
1. First check the clamp tightening screw to see if it is tight.
If it is tight and slight leakage still occurs, place a piece
of wood on the periphery of the clamp and firmly tap the
wood with a hammer. Repeat this operation around the
edge of the clamp and retighten the clamp screw. If leak
continues, disassemble clamp and pump halves and
check to see that "O" ring is properly seated and no
foreign material is on "O" ring or "O" seat.
Reassemble pump.
