How to Replace a Submersible Water Well Pump - Step-by-Step Guide

How to Replace a Submersible Water Well Pump


Replacing a submersible water well pump can initially seem daunting, but with the right tools and understanding, it can be a manageable DIY project. This guide will walk you through the steps necessary to safely and effectively replace your pump.


Tools and Materials Needed


1. New Submersible Pump Ensure you choose the correct model for your well. 2. Wrench and Pliers For loosening and tightening fittings. 3. PVC Pipe and Fittings If any pipes need to be replaced. 4. Electrical Tape and Wire Connectors For reconnecting the electrical supply. 5. Safety Gear Gloves and goggles for protection.


Step 1 Preparation


Before beginning the replacement, make sure to gather all necessary tools and materials. Turn off the power to the well pump at the circuit breaker to ensure safety while working. Locate the well head, which is usually found above ground.


Step 2 Remove the Existing Pump


Once the power is off, disconnect the electrical connections to the existing pump. Carefully note how the wires are connected, as you will need to replicate this when installing the new pump. Use a wrench to detach the drop pipe from the pump. Be prepared for some water to spill out when you pull the pipe out of the well.


Next, pull the pump to the surface. This may require some muscle, as submersible pumps can be heavy. If your pump is stuck, you might need to add a puller or a winch to help retrieve it.


Step 3 Inspect the Well Components


After removing the pump, inspect the drop pipe and other components for wear or damage. Look for cracks or corrosion that could lead to future issues. Replace any damaged pipes or fittings at this stage before installing the new pump.

Step 4 Install the New Pump


Once the old pump is completely removed and the well inspected, it's time to install the new submersible pump. Begin by attaching the new pump to the drop pipe using the appropriate fittings. Ensure a tight seal to prevent water leaks.


Carefully lower the new pump into the well. Take your time here and avoid any kinks in the drop pipe. Aim for a smooth descent so the pump can sit evenly at the bottom of the well.


Step 5 Reconnect Electrical Connections


With the pump in place, reconnect the electrical wires according to the notes you took earlier. Ensure all connections are secure and properly insulated with electrical tape and wire connectors.


Step 6 Prime the Pump


Before turning the power back on, prime the pump by filling the drop pipe with water if necessary. This step ensures that the pump can begin operating efficiently once powered on.


Step 7 Power On and Test


Finally, restore power to the pump at the circuit breaker. Allow the pump to run for a few minutes and check for any leaks or unusual sounds. If everything appears to be functioning correctly, you have successfully replaced your submersible water well pump.


Conclusion


By following these steps carefully, you can replace your submersible water well pump with confidence. Always remember to prioritize safety, and don’t hesitate to consult a professional if you encounter issues beyond your expertise. Regular maintenance of your well system will help ensure continued reliable water supply for your home.
