TROUBLESHOOTING CHART
SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Motor will not run 1. Disconnect switch is off 1. Be sure switch is on
2. Fuse is blown 2. Replace fuse
3. Starting switch is defective 3. Replace starting switch
4. Wires at motor are loose, 4. Refer to instructions on wiring. Check and tighten all wiring.
disconnected, or wired incorrectly
Pressure switch contacts are dirty 5. Clean by sliding pieces of plain paper between contacts
Motor is v_lred incorrectly 1. Refer to instructions on wiring
Voltage is too low 2. Check with power company. Install heavier wiring if wire
size is too small. See wiring instructions
Pump cycles too frequently 3. See section below on too frequent cycling

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
Captive Air* Tank
Models 390.2519 and 390.2522
require 40 pounds for
proper operation
Pump is picking up prime

a. Re-ptime according to instructions
b. Check all connections on suction line, air voltlme 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 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. Check possibility of using a deep well jet pump
5. Refer to instructions on wiring
1. Drain tank to air volume control tapping. Check air volume control for
defects. Check for air leaks at any connection
2. Check connections
3. Close faucets or valves
4. Replace foot valve
5. Replace pressure switch
6. 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.
As soon as pump picks up prime, all air will be ejected
Check suction piping
Change installation as described in manual
Lower foot valve if possible, otherwise restrict discharge side of pump
