SUBMERSIBLE PUMP TROUBLESHOOTING
 

E - PUMP WILL NOT SHUT OFF

CAUSE OF TROUBLE

HOW TO CHECK

HOW TO CORRECT

1. Defective pressure switch.

Arcing may have caused pressure switch points to “weld” in closed position. Examine points and other parts of switch for defects.

Clean points or replace switch.

2. Water level in well too low.

Well production may be too low for pump capacity. Restrict flow of pump output, wait for well to recover, and start pump.

If partial restriction corrects trouble, leave valve or cock at restricted setting. Otherwise, lower pump in well if depth is sufficient. Do not lower if sand clogging might occur.

3. Leak in drop line.

Raise pipe and examine for leaks.

Replace damaged section of drop pipe.

4. Pump parts worn.

The presence of abrasive in the water may result in wear on the impeller, casing, and other close clearance parts. Before pulling pump, reduce setting on pressure switch to see if pump shuts  off. If it does, worn parts are probably at fault.

Pull pump and replace worn components.
