well pump repair

27December 2022

A well pump is an essential component of a well system that helps bring water up from the ground to the surface.

If your well pump is not working properly, you may experience low water pressure, no water at all, or dirty water.

Here is a comprehensive guide to repair a well pump:

  1. Identify the problem: The first step in repairing a well pump is to identify the problem. Some common issues include a malfunctioning pressure switch, a faulty motor, or a clogged impeller.
  2. Check the power supply: If your well pump is not working, one of the first things to check is the power supply. Make sure the circuit breaker has not tripped and that the outlet is receiving power. If the problem is with the power supply, it may be as simple as resetting the circuit breaker or replacing a blown fuse.
  3. Check the pressure switch: The pressure switch is responsible for turning the well pump on and off as needed. If the pressure switch is not functioning properly, it can cause the well pump to run continuously or not run at all. To test the pressure switch, you will need a pressure gauge. Place the gauge on the pipe leading to the pressure switch and observe the readings. If the pressure is too low, the switch may need to be adjusted. If the pressure is too high, the switch may be faulty and need to be replaced.
  4. Check the motor: If the power supply and pressure switch are functioning properly, the next step is to check the motor. First, try resetting the motor by flipping the reset switch (if equipped). If the motor still does not start, it may be damaged and need to be replaced.
  5. Check the impeller: If the motor is functioning properly, the next step is to check the impeller. The impeller is responsible for moving the water from the well to the surface. If the impeller is clogged, it can cause a decrease in water flow or a complete loss of water. To check the impeller, remove the motor and inspect the impeller for any debris or damage. If necessary, clean or replace the impeller.
  6. Test the system: Once all necessary repairs have been made, you need to test  to ensure it is working properly. Turn the pump on and observe the water flow and pressure. If the pump is working properly, the water flow should be strong and the pressure should be consistent.

Well pump repairs can be complex and should only be attempted by a qualified professional.

If you are not comfortable making the repairs yourself, it is recommended to hire a licensed plumber or well contractor to perform the repairs.



  1. Identify the problem: The first step in repairing a well pump is to determine what the problem is. Some common problems include a loss of water pressure, a lack of water, or dirty or contaminated water.
  2. Gather necessary tools and materials: Depending on the nature of the problem, you may need a variety of tools and materials to complete the repair. Some common tools and materials include a voltage tester, a pipe wrench, a pipe cutter, pliers, a pipe thread sealant, and replacement parts such as seals, gaskets, and impellers.
  3. Shut off power and water: Before beginning any repair work, it is important to shut off the power to the well pump and the water supply to the house. This will prevent accidents and ensure that the repair work can be completed safely.
  4. Inspect the well pump: Once the power and water have been shut off, you can begin inspecting the well pump. Look for any visible damage or wear, such as cracks, leaks, or loose bolts. Check the electrical connections to ensure that they are secure and free of corrosion.
  5. Test the well pump: Once you have completed your inspection, you can test the well pump to determine if it is functioning properly. To do this, you will need to turn the power and water back on and run the pump for a few minutes. Pay attention to the flow rate, water pressure, and overall performance of the pump.
  6. Replace any damaged or worn parts: If you identify any damaged or worn parts during your inspection or testing, you will need to replace them. Depending on the nature of the repair, this may involve removing the pump from its casing, disassembling it, and replacing the necessary parts.
  7. Reassemble and test the well pump: Once you have replaced any damaged or worn parts, you can reassemble the well pump and test it again to ensure that it is functioning properly.
  8. Clean and maintain the well pump: Regular cleaning and maintenance of your well pump can help to extend its lifespan and prevent future problems. This may involve cleaning the exterior of the pump, inspecting and replacing the well filter, and checking the electrical connections.

It’s important to note that well pump repairs can be complex and may require the assistance of a professional. If you are unsure about how to complete a repair or do not feel comfortable working on the pump, it is recommended that you hire a qualified technician to handle the repair work.
