SYMPTOM 

POSSIBLE CAUSE(S) 

CORRECTIVE ACTION

  Motor will not run 

Disconnect switch is off 

Be sure switch is on.

    

Fuse is blown or circuit breaker tripped 

Replace fuse or reset circuit breaker.

    

Starting switch is defective 

DISCONNECT POWER; Replace starting switch.

    

Wires at motor are loose,  

Refer to instructions on wiring (Pages 7 and 8). DISCONNECT POWER;  

  

disconnected, or wired incorrectly  

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.

   

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 ejector with

   

 

      soapy water or shaving cream.

    

  3. Leaking foot valve or check valve 

  3. Replace foot valve or check valve.

    

Pump has lost prime through: 

In installation already in use: 

     

  1. Air leaks 

  1. Check all connections on suction line and shaft seal. 

    

  2. Water level below suction pipe inlet 

  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.

   

Foot valve or strainer is plugged 

Clean foot valve or strainer.

   

Ejector or impeller is plugged 

Clean ejector or impeller.

   

Check valve or foot valve is stuck shut  

Replace check valve or foot valve.

    

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 bottom of water source. 

    

buried in sand or mud 

Clean foot valve and strainer.

   

Water level is too low for shallow well   

A deep well jet package may be needed (over 25 ft. to water)  

   

setup to deliver water 

to deliver water.

  Pump does not  

Water level in well is lower than  

A new jet and venturi combination may be needed. 

  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

    

Piping is too small in size 

Use larger piping.

    

Packed well point 

Backflush well point or sink new point.

  Pump delivers water but 

Pressure switch is out of adjustment or 

DISCONNECT POWER; adjust or replace pressure switch. 

  does not shut off or 

contacts are welded together

  pump cycles too 

Faucets have been left open 

Close faucets.

  frequently 

Venturi, nozzle or impeller is clogged 

Clean venturi, nozzle or impeller.

   

Standard pressure tank is waterlogged 

Drain tank to air volume control port. Check AVC for defects. Check 

   

and has no air cushion 

all connections for air leaks.

   

Pipes leak 

Check connections.

   

Foot valves leak 

Replace foot valve.

   

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 (20-40 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. 

Lower foot valve if possible, otherwise restrict pump discharge

    

(Water drawn down below foot valve.)

 

* (Notice: Stop 

pump; then check 

prime before look-

ing for other causes. 

Unscrew priming 

plug and see if water 

is in priming hole).
