Owning property with a deep water well requires that you know how to troubleshoot and fix basic problems, such as no water flow to your home. This basic knowledge will save you a lot of time and money over waiting for a plumbing contractor service call. Follow this procedure to determine the cause of your home's lack of water and fix the problem yourself when possible:
Verify the Submersible Pump Has Power Service
To start troubleshooting your home's water problem, first go to the power panel and locate the breaker labeled for your well's pump. Make sure that the breaker has not been tripped during a recent power surge or power failure. If the breaker was tripped, then resetting it will restore the power to the pump and in a few minutes your home will have water flowing again. The water flow will not be immediate because the pump will need a few minutes to reset itself and start pumping water to the surface again.
Reset the Submersible Pump
Your well's submersible pump has an electronic control unit (ECU) mounted on the wall of your garage or pumphouse. The ECU is a simple device that acts like a surge protector for your well's pump. If excessive current flows into the ECU from the power grid, then the ECU turns off the connection between the pump and the power source to prevent permanent damage to the pump.
Located on the front of the ECU is a reset button. Press the button once and it will reboot the electronics in the submersible pump. Wait for a few minutes and if you still do not have water service, then the pump accessing power is not the problem.
Check the Pressure Tank and Its Pump
If your water system uses a pressure tank and pressure pump to increase the water pressure in your home, then you have a bit more troubleshooting to do. However, if you do not have a pressure tank and pump, then it is time to call a professional well service to come to your home and extract the submersible pump for repair or replacement.
To check the pressure tank, you should gently rock it back and forth. If the tank is heavy with water and there are no obvious leaks, then the pressure tank is likely working correctly. If you open a water tap near the pressure tank and the pressure pump turns on, then you know that the pressure pump is not the problem. If the pump does not come on as you drain water and lower the system's pressure, then the pump needs to be replaced.
