How to Replace a Submersible Water Well Pump


Replacing a submersible water well pump can seem daunting, but with the right tools and guidance, it can be accomplished in a systematic way. This guide will walk you through the essential steps involved in the process, helping you restore your water supply efficiently.


Understanding Submersible Water Well Pumps


A submersible water well pump is a type of pump that is submerged underwater within a well. It is designed to push water to the surface, unlike jet pumps, which pull water. These pumps are efficient and often last for years, but like any mechanical device, they may eventually need replacement due to wear and tear or malfunction.


Tools and Materials Needed


Before you begin the replacement, gather the following tools and materials


- New submersible well pump - Pipe wrench - Plumber's tape - Safety glasses and gloves - Bucket or hose (for draining) - Wire cutter/stripper - Height measuring tape - Rope or lifting strap


Step-by-Step Replacement Process


1. Turn Off Power The first step is to ensure your safety. Turn off the power to the well pump at the circuit breaker to avoid any risk of electrocution.


2. Remove the Well Cover Depending on your setup, you may need to remove a protective casing or cover above the well to access the pump’s components.


3. Disconnecting the Pipes Carefully detach the discharge pipe connected to the pump using a pipe wrench. Be prepared for some residual water flow, so have a bucket or hose ready to catch any spills.

4. Pulling the Pump This is usually the most challenging part. Attach a rope or lifting strap to the pump and slowly pull it out of the well casing. Be cautious, as the pump may be heavy and may have sections that can break if too much force is applied. If the pump is stuck, gently rock it to loosen it.


5. Inspect the Old Pump Once the pump is out, take a moment to inspect it for obvious signs of damage. This could help you understand the reason for the failure, which is valuable knowledge for preventing future issues.


6. Prepare the New Pump Before installing the new pump, ensure that it matches the specifications of the old one, including size and power requirements. Install the new pump's fittings as per the manufacturer's instructions.


7. Lowering the New Pump Carefully lower the new submersible pump down into the well. Ensure that the wiring is properly managed and that it is not tangled or pinched as the pump goes down.


8. Reconnect the Pipes Once the pump is in place, reconnect the discharge pipe and ensure it is secure. Use plumber's tape to prevent leaks.


9. Restore Power After everything is in place, turn the power back on at the circuit breaker. Monitor the pump to ensure it’s operating correctly. Listen for any strange noises and check for leaks around the pipes.


10. Final Checks After a few minutes of operation, check the water flow at your faucets. Ensure it is consistent and free of air bubbles, which can indicate that the pump is not functioning correctly.


Maintenance Tips


To prolong the life of your submersible pump, regular maintenance is crucial. Periodically check the well for any debris or silt accumulation. Ensure that the electrical components are dry and that connections are secure.


Conclusion


Replacing a submersible water well pump may require some effort, but by following these steps, you can successfully restore your water supply. Always remember to prioritize safety by turning off the power, wearing safety gear, and taking your time throughout the process. If at any point you feel unsure about completing the task, don’t hesitate to call a professional for assistance.
