Troubleshooting
13
Symptom
Motor will not run
Motor runs hot and overload
kicks off
Motor runs but no water is
delivered*
* Stop pump; then check
prime before Iooldng for
other causes. Unscrew
priming
plug and see if
water is in priming
hole.
Pump does not deliver water
to full capacity (Also check
point ¢ immediately
above)
Pump delivers water but does
not shut off or pump cycles
too frequently
Air spurts from faucets
Possible Cause(s)
Disconnect
switch
is off
Fuse is blown
or circuit
breaker tripped
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:
1. Improper
priming
2. Air leaks
¢. I ealdng foot valve or check valve
Pump has lost prime through:
1. Air leaks
2. Water level below suction pipe inlet
Foot valve or strainer is plugged
Ejector or impeller
is plugged
Check valve or foot valve is stuck shut
Pipes are frozen
Foot valve and/or strainer are buried in
sand or mud
Water level is too low for shallow well
setup to deliver water
Water level in well is lower than estimated
Corrective
Action
Be sure switch is on.
Replace fuse or reset circuit
breaker.
DISCONNECT
POWER; Replace starting switch.
Refer to instructions
on wiring
(Page 9). DISCONNECT
POWER; check and
tighten all wiring.

To discharge capacitor,
hold insulated

BY THE HANDLE and short capacitor
[ terminals
together.
Do not touch
metal screwdriver
[)lade or capacitor
terminals.
If in doubt, consult a qualified
electrician.
DISCONNECT
POWER and file contacts with emery board or nail file.
Refer to instructions
on wiring.
Check with
power company.
Install heavier wiring
if wire size is too small (See
Electrical / Wiring
Chart).
See section below on too frequent cycling.
In new installation:
1. Re-prime
according to instructions.
2. Check all connections
on suction
line, AVC, and ejector with soapy water or
shaving cream.
_¢.Replace foot valve or check valve.
In installation
already
in use:
1. Check all connections
on suction
line and shaft seal.
2. lower
suction line into water and re-prime. If receding water level in well
exceeds 25' (7.6M), a deep well pump is needed.
Clean foot valve or strainer.
Clean ejector or impeller.
Replace check valve or foot valve.
[ Thaw pipes. Bury pipes below frost line. Heat pit or pump house.
Raise foot valve and/or strainer above bottom of water source. Clean foot valve
and strainer.
A deep well jet will be needed if your well is more than 25' (7.6M) depth to
water.
A new nozzle and venturi combination
may be needed.
Steel piping (if used) is corroded
or limed,
causing excess friction
Piping is too small in size
Pressure switch is out of adjustment
or
contacts are welded together
Faucets have been left open
Venturi,
nozzle or impeller
is clogged
Standard pressure tank is waterlogged
and
has no air cushion
Pipes leak
Foot valve leaks
Pressure switch is out of adjustment
Air charge too low in pre-charged
tank
Pump is picldng up prime
leak in suction side of pump
Well is gaseous
Intermittent
over-pumping
of well. (Water
drawn down below foot valve.}
Replace with plastic pipe where possible, otherwise
with
new steel pipe.
Use larger piping.
DISCONNECT POWER;adjust or replace pressure switch.
Close faucets.
Clean venturi,
nozzle or impeller.
Drain tank to air volume
control port. Check AVC for defects. Check all
connections
for air leaks.
Check connections.
Replace foot valve.
Adjust or replace pressure switch.
DISCONNECT
POWER and open faucets until all pressure is relieved.
Using
i tire pressure gauge, check air pressure in tank at valve stem located on the tank.
If less than pressure switch cut-in setting (30-50 PSI), pump air into tank from
outside source until air pressure is 2 PSI less than cut-in setting of switch. Check
air valve for leaks {use soapy solution) and replace core if necessary.
I When
pump has picked up prime, it should pump solid water with no air.
Suction pipe is sucldng air. Check joints for leaks with soapy water.
Consult factory about installing
a sleeve in the well.
lower
foot valve if possible, otherwise
restrict pump discharge.
