Troubleshooting

SYMPTOM POSSIBLE CAUSE(S)
Motor will not run 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 runs hot and Motor is wired incorrectly
overload kicks off
Voltage is too low
Pump cycles too frequently
Motor runs but no Pump in new installation did
water is delivered* not pick up prime through:
1. Improper priming
2. Air leaks
* (Note: Stop pump; 3. Leaking foot valve or check valve
then check prime
Pump has lost prime through:
before looking for
1. Air leaks
other causes.
2. Water level below suction pipe inlet
Unscrew priming
plug and see if water
Foot valve or strainer is plugged
is in priming hole).
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
Pump does not Water level in well is lower than
deliver water to full estimated
capacity
Steel piping (if used) is corroded or
(Also check point
limed, causing excess friction
3 immediately above)
Piping is too small in size
Pump delivers water but Pressure switch is out of adjustment or
does not shut off or contacts are welded together
pump cycles too
Faucets have been left open
frequently
Venturi, nozzle or impeller is clogged
Standard pressure tank is waterlogged
and has no air cushion
Pipes leak
Foot valves leak
Pressure switch is out of adjustment
Air charge too low in pre-charged tank
Air spurts from faucets Pump is picking up prime
Leak in suction side of pump
Well is gaseous
Intermittent over-pumping of well.
(Water drawn down below foot valve.)
CORRECTIVE ACTION
Be sure switch is on.
Replace fuse or reset circuit breaker.
DISCONNECT POWER; Replace starting switch.
Refer to instructions on wiring (Pages 7 and 8). DISCONNECT POWER;
check and tighten all wiring.
Capacitor voltage may be hazardous. To discharge
capacitor, hold insulated handle screwdriver BY THE HANDLE and
short capacitor terminals together. Do not touch metal screwdriver
blade 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.
3. 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 20' (6.1M), 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 20' (6.1M)
depth to water.
A new nozzle and venturi combination may be needed.
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 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.
When pump has picked up prime, it should pump solid water with no air.
Suction pipe is sucking 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.
