Changing a Submersible Well Pump A Step-by-Step Guide


Changing a submersible well pump can seem daunting, but with the right tools and knowledge, it can be a manageable task. A submersible well pump is designed to be submerged in water, pushing it to the surface for household or agricultural use. Over time, these pumps can wear out or fail due to various reasons, including mineral buildup, corrosion, or mechanical failure. Here’s a step-by-step guide to help you change your submersible well pump effectively.


Step 1 Gather Your Tools and Materials


Before starting the replacement, ensure you have all the necessary tools. You will need a wrench set, pliers, a screwdriver, a bucket for water, a pipe wrench, safety glasses, and gloves. Additionally, have your new pump ready for installation, along with any needed fittings or connectors.


Step 2 Turn Off the Power Supply


Safety should always be your first priority. Begin by turning off the power supply to the well pump at the circuit breaker. This will prevent any accidental activation during the replacement process.


Step 3 Remove the Well Cap


Next, access the well by removing the well cap. This usually involves unscrewing a few bolts. Be cautious of any debris that may fall into the well during this time.


Step 4 Disconnect the Pump Wiring


Carefully disconnect the electrical wires connected to the old pump. It’s essential to label the wires to ensure you know where they go when connecting the new pump. Use wire nuts to secure the ends temporarily.

Step 5 Pull Out the Old Pump

Using a pipe wrench, loosen the fittings connecting the pump to the discharge pipe. Once loosened, you can attach a lifting system or a cable to the pump and pull it out of the well gently. Make sure to do this slowly to avoid damaging the pump or the well casing.


Step 6 Install the New Pump


Once the old pump is out, it’s time to install the new one. Lower the new submersible pump into the well while ensuring it hangs straight. Reattach the discharge pipe and tighten the fittings securely.


Step 7 Reconnect the Wiring


Follow the labels you made earlier to reconnect the electrical wires to the new pump. Ensure that all connections are tight and secure to prevent any electrical issues.


Step 8 Test the New Pump


Finally, replace the well cap and restore power to the pump at the circuit breaker. Turn on the water supply and check for leaks at the fittings. Observe the pump in action to confirm that it’s operating correctly.


Changing a submersible well pump can be a straightforward process when you follow these steps. Regular maintenance and timely replacement will ensure you enjoy a reliable water supply for years to come.
