Disconnect switch is off
Fuse is blown
Starting switch is defective
Wires at motor are loose,
disconnected, or wired incorrectly
Pressure switch contacts are
dirty
Motor is wired incorrectly
Voltage is too low
Pump cycles too frequently
Pump in new installation did
not pick up prime through:
a. Improper priming
b. Air leaks
c. Leaking foot valve
Pump has lost prime through:
a. Air leaks
b. Water level below suction
of pump
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
Water level in well is lower than
estimated
Steel piping (if used) is corroded or
limed, causing excess friction
Offset piping is too small in size
Pressure switch is out of adjustment
or contacts are "frozen"
Faucets have been left open
Jet or impeller is clogged
Water level in well is lower than
estimated
Motor is wired incorrectly
Standard pressure tank is water-
logged and has no air cushion
Pipe leak
Faucets or valves are open
Foot valve leaks
Pressure switch is out of adjustment
Air charge too low in

Model 390.251182 requires 30
pounds and Models 390.251982
and 390.252282 require 40
pounds for proper operation
Pump is picking up prime
Leak in suction side of pump
Well is gaseous
Intermittent over-pumping of well
CORRECIIVE ACI'ION
1. Be sure switch is on
2. Replace fuse
3. Replace starting switch
4. Refer to instructions on wiring. Check and tighten all wiring.
5. Clean by sliding pieces 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, air volume control, and jet
c. Replace foot valve
2. In installation already in use:
a. Check all connections on suction line, air volume control,
jet and shaft seal
b. Lower suction line into water and re-prime. If receding water level
in well exceeds suction lift, a deep well pump is needed
3. Clean jet or impeller according to instructions
4. Replace check waive 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. Check possibility of using a deep well jet pump
5. Refertoinstructionsonwiring

Drain tank to air volume control tapping. Check air volume control for
defects. Check for air leaks at any connection
Check connections
Close faucets or valves
Replace foot valve
Replace pressure switch
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 air pressure is lower, pump air
into tank from outside source until proper air 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
3. Change installation as described in manual
4. Lower foot valve if possible, otherwise restrict discharge side of pump
