TROUBLE
Motor will not run Disconnect switch is off
Fuse is blown
Starting switch is defective
Wires at motor are loose, disconnected, or
wired incorrectly
*Motor is wired incorrectly
Pressure switch contacts are dirty
Motor runs hot and *Motor is wired incorrectly
overload kicks off
Voltage is too low
Pump cycles too frequently
Motor runs but no *Pump in a new installation did not pick up
water is delivered prime through:
a. Improper priming
(*Note: Check prime
b. Air leaks
before looking for
c. Leaking foot valve
other causes.
Unscrew priming
*Pump has lost its prime through:
plug and see if there
a. Air leaks
is water in priming
b. Water level below suction of pump
hole)
Jet or impeller is plugged
Check valve or foot valve is stuck in closed
position
Pipes are frozen
Foot valve and/or strainer are buried in sand or
mud
Pump does not Water level in well is lower than
deliver water to full
Steel piping (if used) is corroded or limed,
capacity (also check
causing excess friction
point 3 immediately
Offset piping is too small in size
above)
Pump pumps water Pressure switch is out of adjustment
but does not shut off contacts are "frozen"
Faucets have been left open
Jet or impeller is clogged
Motor is wired incorrectly
Water level in well is lower than estimated
Pump cycles too Pipes leak
frequently
Faucets or valves are open
Foot valve leaks
Pressure switch is out of adjustment
Air charge too low in Captive Air® Tank
Air spurts from Pump is picking up prime
faucets
Leak in suction side of pump
Well is gaseous
Intermittent over-pumping of well
Leaks at the metal Loose clamps or "O" ring not sealed
clamp
Release all pressure
in system before
working on clamp!

REMEDIES
Be sure switch is on
Replace fuse
Replace starting switch
Refer to instructions on wiring
Refer to instructions on wiring
Clean by sliding piece of plain paper between contacts
Refer to instructions on wiring
Check with power company. Install heavier wiring
small. See wiring instructions
See section below on too frequent cycling
In new installation:
a. Re-prime according to instructions
b. Check all connections on suction line and jet
c. Replace foot valve
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
Clean jet or impeller according to instructions
Replace check valve or foot valve
Thaw pipes. Bury pipes below frost line. Heat pit or
Raise foot valve and/or strainer above well bottom
A deep well jet pump may be needed (over 20 ft. to water)
Replace with Plastic Pipe where possible, otherwise with new steel pipe
Use larger offset piping
Adjust or replace pressure switch
Close faucets
Clean jet or impeller
Refer to instructions on wiring
Check possibility of using a deep well jet pump
Check connections, replace pipe fittings
Close faucets or valves
Replace foot valve
Adjust or replace pressure switch
Disconnect electrical power and open faucets until all
relieved. Using automobile tire pressure gauge, check air pressure in tank
at the valve stem located at top of tank. If less than 40 pounds, pump air
into tank from outside source, until 40 pounds pressure is reached. Check
air valve for leaks, using soapy solution, and replace core if necessary
As soon as pump picks up prime, all air will be ejected
Check suction piping, make sure joints are not sucking air
Change installation as described in manual
Lower foot valve if possible, otherwise restrict discharge
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.
