In order to troubleshoot a water well pump, follow the troubleshooting tips outlined in the owner's manual. Ensure the power is off at the breaker before performing any troubleshooting tasks.
Some basic troubleshooting tips for well pumps are:
- Check the voltage
- Inspect the wiring
- Inspect the power wires
- Test the starting components
- Check the depth to water
- Inspect the check valve
- Inspect the drop valve
- Inspect the connector shaft
Check the motor's voltage rating and ensure the connected voltage matches.
Check the power at the fuse box and ensure the power was turned in the on position when the pump was not working. Then inspect the wiring and pressure switch to identify the cause.
Inspect and repair any loose or damaged wires at the pump's motor and the pressure switch.
Test the capacitor and other starting components and either repair or replace the pump or motor as necessary.
If the well is too low or too high for the pump's rating, it will not be able to sufficiently operate. Use a pump that is compatible with the well's conditions.
A stuck or improperly installed check valve can keep the pump from operating correctly. Re-install or replace the check valve.
Inspect the drop valve for leaks or loose joints and repair or replace as necessary.
The connector shaft that connects the motor to the wet end can wear, so repair or replace as necessary.
There are many components that can fail, so check the owner's manual for model-specific troubleshooting tips.
