Guide to Changing a Submersible Well Pump Efficiently and Safely

How to Replace a Submersible Water Well Pump


Replacing a submersible water well pump can seem like a daunting task, but with proper guidance and preparation, it can be completed successfully. In this article, we'll walk you through the essential steps to ensure your new pump operates efficiently and meets your household water needs.


Understanding Submersible Water Well Pumps


Submersible pumps are designed to be submerged underwater and push water to the surface. These pumps are efficient and suitable for deep wells. However, over time, they can wear out due to age, sediment buildup, or mechanical failure. Signs that your pump may need replacement include decreased water flow, unusual noises, or no water at all.


Tools and Materials Needed


Before starting the replacement process, gather the necessary tools and materials


1. New Submersible Pump Ensure you have the correct pump size and capacity for your well. 2. Wrenches Adjustable wrenches or socket sets for loosening fittings. 3. PVC Pipe and Fittings For connecting the pump to the above-ground plumbing. 4. Electrical Tools Wire strippers, electrical tape, and safety glasses. 5. Safety Gear Gloves and sturdy boots for protection. 6. Hoisting Equipment A winch or a sturdy rope to lift the pump out of the well. 7. Bucket or Container To catch excess water during removal.


Step-by-Step Replacement Process


1. Turn Off the Power Supply


Before doing any work, turn off the power to the well pump at the circuit breaker. This is crucial for your safety. Verify that the power is off by using a voltage tester on the pump’s control box.


2. Remove the Well Cap


Use a wrench to detach the well cap. Be cautious, as some water may spill out of the well casing.


3. Disconnect the Pump Wiring


Carefully disconnect the electrical wiring from the pump. Take note of how the wiring is connected; you may want to take a photo for reference when installing the new pump.


4. Detach the PVC Pipe


Use your wrenches to disconnect the PVC pipe connecting the pump to the surface plumbing. It’s important to do this carefully to avoid damaging the pipes.

5. Lift the Old Pump Out

Attach your winch or a sturdy rope to the pump. Slowly and carefully lift the pump out of the well. If it seems stuck, gently rock it back and forth to free any obstructions.


6. Prepare the New Pump


Before lowering the new pump, ensure it matches the specifications of the old one. Double-check that the pump is configured for use in your specific well depth and water requirements.


7. Lower the New Pump Into the Well


Carefully lower the new pump into the well. Keep an eye on the wiring and ensure it doesn't twist or tangle.


8. Reconnect the PVC Pipe and Wiring


Once the pump is in place, reconnect the PVC pipe, ensuring all fittings are tight to prevent leaks. Then, connect the electrical wiring according to the notes or photographs you took earlier.


9. Replace the Well Cap


Securely replace the well cap. This is crucial to prevent contaminants from entering the well.


10. Turn On the Power Supply


Return to the circuit breaker and turn the power back on. Check the pump for proper operation. You should hear it start and see water flowing through the plumbing.


Final Checks


After installation, watch for any leaks around the connections and ensure the water pressure is stable. It may take a few minutes for air to clear from the system. If everything appears to be functioning as expected, congratulations! You’ve successfully replaced your submersible water well pump.


Conclusion


Replacing a submersible water well pump requires careful planning and execution, but it is certainly achievable. By following the steps outlined above and adhering to safety protocols, you can ensure a smooth installation process and restore reliable water flow to your home. Remember, if at any point you feel uncomfortable with the process, don’t hesitate to seek professional assistance.
