Introduction

A submersible well pump is a crucial component to ensure efficient water supply in your property. Over time, the pump may wear out or get damaged, and it becomes necessary to replace it. Replacing a submersible well pump may seem like an overwhelming task, but with the proper tools and guidelines, you can successfully perform the replacement yourself. The following steps will guide you on how to replace a submersible well pump.

Step 1: Gather the Necessary Tools and Materials

Before starting any work, gather all the necessary tools and replacement materials you will need. These include:

– New submersible pump

– Teflon tape

– Torque arrestor

– Cable guard

– Pitless adapter

– Safety rope or cable

– Pipe wrenches

– Channel lock pliers

– Hacksaw or PVC cutter (if needed)

Step 2: Disconnect Power Supply

For safety purposes, switch off the electrical circuit connected to the well pump at the breaker box before handling any electrical components of the system.

Step 3: Access the Well Pump

Remove the well cap or seal from the top of your well casing. Gain access to your submersible pump by disconnecting any pipes connected to it using a wrench. Be prepared for some water spillage during this process.

Step 4: Remove the Old Submersible Pump

Detach any safety ropes or cables connected to the old pump. Carefully pull out the entire assembly of piping and wiring from the well casing, taking note of how everything was connected. It may be helpful to have an assistant help you with this step.

Step 5: Inspect and Prepare for Installation

Once you have removed the old pump and its components, inspect them for signs of wear and damage while also making note of part measurements for future reference. Clean up any rust or debris found before moving on to installing the new submersible well pump.

Step 6: Prepare the New Pump

Attach the torque arrestor to your new pump and connect the pitless adapter using Teflon tape to secure the threads. Connect the pump electrical wiring according to the manufacturer’s instructions. Securely fasten a safety rope or cable to your new pump, ensuring it is long enough to reach the bottom of your well.

Step 7: Install the New Submersible Pump

Carefully lower the new pump into the well, ensuring that it is positioned straight and slowly fed down to its designated depth. Connect your new pump to the existing pipe assembly and make any necessary adjustments for a proper fit.

Step 8: Test the System

Once everything is connected, switch on the power supply and allow water to flow through your system for a few moments. Observe for any leaks or unusual sounds and correct any issues found before putting your well fully back in operation.

Step 9: Reinstall Well Cap or Seal

With successful testing completed, reinstall your well cap or seal atop your well casing, ensuring it is secure and watertight.

Conclusion

Replacing a submersible well pump can be a challenging task but with adequate preparation and patience, you can successfully complete this project yourself. Regular maintenance checks and addressing any issues early will help prolong the life of your well pump and overall water system.
