Troubleshooting II
Symptom
Motor will not run
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
Pressureswitch contacts are dirty
Motor runs hot and overload Motor is wired incorrectly
kicks off
Voltage is too low
Motor runs but no water is
delivered*
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
* Stop pump; then check
prime before looking for
other causes. Unscrew
priming plug and see if
water is in priming hole.
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
Pump does not deliver water Water level in well is lower than estimated
to full capacity (Also check
Steel piping (if used) is corroded or limed,
point _¢immediately above)
causing excess friction
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.
I ,_WARNING I Cal)acitor voltage may be hazardous. To discharge capacitor,
hold insulated handle screwdriver BY IHE 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.
_¢. 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.
Replace with plastic pipe where possible, otherwise with new steel pipe.
Piping is too small in size Use larger piping.
Pump delivers water but does Pressure switch is out of adjustment or DISCONNECT POWER; adjust or replace pressure switch.
not shut off or pump cycles contacts are welded together
too frequently Faucets have been left ol)en Close faucets.
Venturi, nozzle or impeller is clogged Clean venturi, nozzle or impeller.
Standard pressure tank is waterlogged and Drain tank to air volume control port. Check AVC for defects. Check all
has no air cushion connections for air leaks.
Pipes leak Check connections.
Foot valve leaks Replace foot valve.
Pressure switch is out of adjustment Adjust or replace pressure switch.
Air charge too low in pre-charged tank DISCONNEC[ POWER and (}pen 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.
Air spurts from faucets Pump is picking up prime When pump has picked up prime, it should pump solid water with no air.
leak in suction side of pump Suction pipe is sucking air. Check joints for leaks with soapy water.
Well is gaseous Consult factory about installing a sleeve in the well.
Intermittent over-pumping of well. (Water lower foot valve if possible, otherwise restrict pump discharge.
