Troubleshooting
Do Do Not
 Remove the drain plug (located on the front of the pump close
to the inlet hole) and air plug (located on the top of the pump
close to the outlet hole) to vent the system.
 Drain all piping to a point below the freeze line.
NOTE: While this will drain the pump, it will not necessarily
drain all the unprotected parts of the piping system. To drain
the tank, disconnect the piping at the tank outlet.
 Do not disassemble the motor housing. This motor has NO
repairable internal parts, and disassembly may cause
dangerous electrical wiring issues.
Problem Possible Cause Corrective Action
Pump humming. 1. The motor shaft stuck.
2. Selected wrong voltage.
1. 1.1 Please use a flat head screw driver to turn
the motor shaft through the center hole on the
motor cap. Then restart the pump.
1.2 Clean impeller and diffuser.
2. Pump was pre-set at 230V. Refer to manual for
set voltage to 115V.
Does not pump water or low flow. 1. Air in piping or did not prime.
2. The water level in the well is below the foot
valve.
3. The foot valve is plugged or leaks.
4. Impeller or nozzle blocked by foreign
material.
1. Stop the motor. Remove the pressure gauges or
prime plug. Fill the housing pipes with water.
2. Lower the suction pipe. If the water level is
more than 25 ft., you need a deep well pump.
3. Replace the foot valve or dig the well deeper.
4. Clean impeller and nozzle.
Pump does not stop or pressure
does not build up.
1. Impeller or nozzle blocked by foreign
material.
2. There is a leak in the house piping.
1. Clean impeller and nozzle.
2. Locate and repair the leak or reconnect.
The pump starts and stops too
often.
1. Pressure in pre-charged tank is not correct.
2. The pressure switch malfunctioning.
3. There is a ruptured diaphragm/bladder (pre-
charged tank).
1. Ensure the pressure in the pre-charged tank is
set to 2 PSI less than the cut-in pressure.
2. Replace the pressure switch .
3. Replace the tank.
