DIY Guide: How To Replace A Well Pump

Posted on: 29 August 2023

A well pump is the heart of your home's water system and is responsible for delivering water from underground sources to your taps. When it fails, it can be a major inconvenience, and you may need to replace it. Below are steps to guide you through the process of replacing a well pump, but remember that this is a complex job that often requires professional expertise.

Important Note: Always ensure you have turned off all power sources before starting any water pump work to avoid accidents.

Step 1: Gather Your Tools and New Pump

Before starting, make sure you have all the necessary tools: pipe wrenches, Teflon tape, a new well pump, and safety gear (like gloves and safety glasses). Choose a new pump that matches your well's specifications.

Step 2: Disconnect the Old Pump

First, turn off the circuit breaker for the well pump. Then, disconnect the well cap by removing the bolts that hold it in place. You should now see the well's casing and wires. Disconnect the wires and mark them so you can easily reconnect them to the new pump.

Step 3: Remove the Old Pump

With the help of a hoist or winch, start pulling up the piping. Be careful not to pull too quickly, as you don't want to damage the pitless adapter. Once the pipe is removed, you'll be able to remove the old pump.

Step 4: Attach the New Pump

Before attaching the new pump, wrap the threads of the pipe with Teflon tape to create a watertight seal. Attach the new pump to the pipe using pipe wrenches. Make sure it's secure before proceeding.

Step 5: Reinstall the Pump

Using the hoist or winch, slowly lower the new pump into the well. Be sure to keep the pipe straight as you lower it to prevent damage. Once the pump is in place, reconnect the wires according to the markings you made earlier.

Step 6: Test the New Pump

Turn on the circuit breaker and run water from a faucet to test the new pump. It may take a few minutes for the water to flow, as the pump needs to pressurize the system. If the water flows properly, replace the well cap.

Step 7: Clean Up

Finally, clean up your workspace and dispose of the old pump properly. Many local recycling centers accept old well pumps.

Replacing a well pump can be a challenging undertaking, as it necessitates the use of specialized tools and a thorough comprehension of your household water system. If you're unsure about any step in the process, it's best to call a professional. Ensuring proper installation is vital for the long-term durability of your new well pump and the optimal efficiency of your water system.
