TROUBLESHOOTING GUIDE


Motor will not run.
Motor runs hot and overload kicks off.
Motor runs but no water is delivered.
Little or no water delivered.
Pump does not deliver water to full capacity.
Pump pumps water but does not shut off.
Pump cycles too frequently.



Motor will not run. Top

1. Disconnect switch is off. 1. Place on "ON" position.
2. Fuse is blown. 2. Replace with proper size fuse.
3. Overload tripped. 3. Reset overload.
4. Defective pressure switch 4. Replace with new switch of proper pressure setting.
5. Incorrect or no voltage. 5. Determine why voltage not available - broken wires, blown fuses, or disconnect switch off. If voltage is incorrect (ref. 115V Service and 230V Pump), customer must purchase proper voltage to match pump.
6. Motor winding open, shorted or grounded. 6. Pull pump and replace motor or complete unit.
7. Low voltage. 7. Check with Power Company. Install heavier wiring if wire size is too small. See wiring instructions.
8. Pump stuck or binding. 8. Pump may be bound from pumping sand. It may be necessary to pull pump and flush out the inside to free it up. Do not reinstall pump in sandy well unless a sandfilter is installed



Motor runs hot and overload kicks off. Top

1. Motor is wired incorrectly. 1. Refer to motor I.D. label for instructions on wiring.
2. Voltage is too low. 2. Check with Power Company. Install heavier wiring if wire size is too small. See wiring instructions.
3. Pump cycles too frequently. 3. See section below on too frequent cycling.



Motor runs but no water is delivered. Top

1. Pump in a new installation did not pick up prime through:
    a. Improper priming
    b. Air leaks
    c. Faulty foot valve
1. In new installation:

    a. Re-prime according to instructions
    b. Check all connections on suction line
    c. Replace or clean foot valve
2. Pump has lost its prime through:
    a. Air leaks
    b. Water level below suction of pump
2. In installation already in use:
    a. Check all connections on suction line
    b. Lower suction line into water and re-prime
3. Jet or impeller is plugged. 3. Clean jet or impeller according to instructions.
4. Check valve or foot valve is stuck in closed position. 4. Replace check valve or foot valve.
5. Foot valve and/or strainer is burring in sand or mud. 5. Raise foot valve and/or strainer above well bottom.
6. Overpumping of well. 6. a. On shallow well operation, lower pipe in water if possible or restrict flow on discharge side of pump.
b. On deep well operation, if possible lower injector into well or add tailpipe to jet assembly.
Otherwise, restrict flow in discharge side of pump.



Little or no water delivered. Top

1. Water level drops below pump inlet when operating. 1. Lower pump in well but no closer than 5 feet from bottom. Throttle discharge between well and tank until discharge between is equal to or less than rate water comes into well.
2. Check valves installed backwards or stuck. 2. Reverse check valves or replace valves if necessary.
3. Shorted run winding in motor. 3. Replace motor or complete pump.
4. Low voltage. 4. Check with Power Company. Install heavier wiring. See wiring instruction
5. Intake screen plugged. 5. Pull pump and clean screen.
6. Pump parts worn. 6. Replace pump end or complete unit.
7. Leak in piping. 7. Replace defective pipe.



Pump does not deliver water to full capacity. Top

1. Water level in well is lower than estimated. 1. A deep well jet pump may be needed if depth to water is greater than 20 feet.
2. Steel piping (if used) is corroded or limed, causing excess friction. 2. Replace with plastic pipe where possible, otherwise with new steel pipe.
3. Piping is too small in size. 3. Use larger piping.
4. Plugged impeller. 4. Clean impeller according to instructions.



Pump pumps water but does not shut off. Top

1. Pressure switch is out of adjustment or contacts are "frozen" closed. 1. Adjust or replace pressure switch.
2. Faucets have been left open. 2. Close faucets.
3. Injector or impeller is clogged. 3. Clean injector or impeller.
4. Water level in well is lower than estimated. 4. Check possibility or using a deep well jet pump, or deep well submersible.



Pump cycles too frequently. Top

1. Standard pressure tank waterlogged (no aircushion). 1. Check for air leaks in tank. Clean bleeder orifices in drop pipe in well (deep well submersible only).
2. Air charge incorrect in captive air tank. 2. Disconnect electrical power, open faucet until all pressure relieved. Check air pressure in tank with tire pressure gauge. Should conform to following, if not, correct:
- 20/40 PSI pressure switch - 18 PSI air pressure in tank
- 30/50 PSI pressure switch - 28 PSI air pressure in tank
- 40/60 PSI pressure switch - 38 PSI air pressure in tank
3. Captive air tank waterlogged (no air cushion). 3. Could be caused by ruptured bladder/diaphragm, leak in metal tank or leak in air sniffer valve. Replace with new tank or consult a captive air tank owner's manual for repair instructions. Do not attempt to repair leaks in metal part of tank.
4. Pipes leak. 4. Repair or replace.
5. Faucets or valves are open. 5. Close faucets or valves.
6. Check valve leaks. 6. Replace check valves.
7. Pressure switch is out of adjustment. 7. Adjust or replace pressure switch.
8. Pressure switch located too far from tank. 8. Move switch to within 12 inches of tank.
