SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Motor will not run Disconnect switch is off Be sure switch is on
Fuse is blown Replace fuse
Starting switch is defective DISCONNECT POWER; Replace starting switch.
Wires at motor are loose, Refer to instructions on wiring. DISCONNECT POWER; check and tighten
disconnected, or wired incorrectly 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.
Pressure switch contacts are dirty DISCONNECT POWER and file contacts with emery board or nail file.
Motor runs hot and Motor is wired incorrectly Refer to instructions on wiring
overload kicks off
Voltage is too low Check with power company. Install heavier wiring if wire size is too small
(See Electrical / Wiring Chart)
Pump cycles too frequently See section below on too frequent cycling.
Motor runs but no *Pump in new installation did In new installation:
water is delivered not pick up prime through:
1. Improper priming 1. Re-prime according to instructions
2. Air leaks 2. Check all connections on suction line, AVC and jet.
3. Leaking foot valve 3. Replace foot valve
* (Note: Check prime *Pump has lost prime through: In installation already in use:
before looking for 1. Air leaks 1. Check all connections on suction line and shaft seal
other causes. Unscrew 2. Water level below suction of pump 2. Lower suction line into water and re-prime. if receding water level
priming plug and see in well exceeds suction lift, a deep well pump is needed
if water is in priming
Jet or impeller is plugged Clean jet or impeller according to instructions.
hole).
Check valve or foot valve is stuck Replace check valve or foot valve
in closed position
Pipes are frozen Thaw pipes. Bury pipes below frost line. Heat pit or pump house.
Foot valve and/or strainer are Raise foot valve and/or strainer above well bottom
buried in sand or mud
Pump does not Water level in well is lower than A deep well jet pump may be needed (over 25 ft. (7.6m) to water)
deliver water to full estimated
capacity
Steel piping (if used) is corroded or Replace with plastic pipe where possible, otherwise with new steel pipe
limed, causing excess friction
Discharge piping is too small in size Use larger discharge piping
Pump delivers water but Pressure switch is out of adjustment or DISCONNECT POWER; adjust or replace pressure switch.
does not shut off.
contacts are 'frozen'.
Faucets have been left open. Close faucets.
Venturi, nozzle or impeller is clogged. Clean venturi, nozzle or impeller.
Water level in well is lower than estimated. Check possibility of using a deep well jet pump.
Pump cycles too Standard pressure tank is waterlogged and Drain tank to air volume control port. Check AVC for defects. Check for
frequently.
has no air cushion. air leaks at any connection.
Pipes leak. Check connections.
Faucets or valves are open. Close faucets or valves.
Foot valves leak. Replace foot valve.
Pressure switch is out of adjustment. Adjust or replace pressure switch.
Air charge too low in pre-charged tank. 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 (40 PSI
(275 kPa)), pump air into tank from outside source until air pres-
sure is 2 PSI (13.8 kPa) less than cut-in setting of switch. Check air valve
for leaks, using soapy solution and replace core if necessary.
Air spurts from faucets. Pump is picking up prime. When pump picks up prime, all air will be ejected.
Leak in suction side of pump. Suction pipe is sucking air. Check joints.
Intermittent over-pumping of well. Lower jet in well if possible, otherwise restrict pump discharge.
