How to Pull a Submersible Well Pump

Submersible well pumps are efficient tools for accessing groundwater. They are submerged deep in the well and are designed to push water to the surface. However, there may come a time when you need to pull your submersible well pump for maintenance, repair, or replacement. This process can be a significant task, but with careful planning and the right tools, it can be accomplished successfully. Below is a comprehensive guide on how to pull a submersible well pump.

Gather the Necessary Tools and Safety Equipment

Before beginning the process, it is essential to gather all necessary tools and equipment. Here’s a checklist of what you might need

- Wrenches and pliers - Pipe wrenches - A bucket or container to catch any water - A hoist or winch (be sure it can handle the weight of the pump) - Electrical tape and wire connectors - A waterproof flashlight for visibility - Safety gloves - Eye protection

Make sure to wear safety gear to protect yourself during the procedure.

Cut Power to the Pump

The first step in pulling a submersible well pump is cutting off the power supply. Locate the electrical switch that controls the pump and turn it off. If there is a circuit breaker, ensure that it is in the ‘off’ position. This is a crucial step to prevent any electrical hazards while working on the pump.

Once the power is off, the next step is to access the pump head. The pump head is located at the top of the well and usually has a protective cover. Remove this cover carefully, using a wrench or any necessary tools. Keep all screws and fasteners in a secure place to avoid losing them.

Disconnect the Electrical Wiring

With the pump head exposed, you will find the electrical connections. Carefully disconnect the electrical wires, making sure to note where each wire connects for later reconnection. Use electrical tape or wire connectors to secure the wires that are not in use, ensuring they do not touch any conductive surfaces.

Remove the Pump from the Well

Now it’s time to pull the pump itself from the well. Attach your hoist or winch to the pump's cable or handle. Make sure that the weight is evenly distributed and that the hoist is securely fastened. Slowly pull the pump out of the well casing. You may need to rotate it gently to ensure that it doesn’t get stuck in the casing or snag on any pipes leading to the pump.

As you pull, have a helper available to guide the pump and monitor the hoist to prevent sudden movements that could damage the pump or your well.

Inspecting the Pump

Once the pump is out, it’s time to conduct a thorough inspection. Check for any signs of wear, corrosion, or damage. Pay special attention to the impeller and motor casing. If any parts appear to be damaged, it may be time to replace the pump.

Also, take this opportunity to inspect the condition of the drop pipe and the electrical cable that runs down to the pump. If you notice any fraying or deterioration, these components should also be replaced.

Reinstallation of the Pump

If your pump is in good condition or has been repaired, it is time to reinstall it. Carefully lower the pump back into the well, ensuring that the electrical wiring is secured and cannot get caught or damaged during the process. Reconnect the electrical connections in the same manner as they were initially removed.

Once everything is securely in place, replace the pump head and restore the power supply. Turn the electrical switch back on, and check for any leaks or abnormal noises.

Conclusion

Pulling a submersible well pump might seem daunting, but with the right tools, safety precautions, and a systematic approach, it can be accomplished successfully. Regular maintenance of your well pump not only extends its lifespan but also allows you to ensure that your water supply remains steady and safe. If you ever feel uncertain about attempting this process, don’t hesitate to consult with a professional.
