How to Remove a Submersible Pump from a Well

Removing a submersible pump from a well can be a daunting task, particularly for those who are not familiar with the intricacies of well systems. However, with the right tools, preparation, and safety precautions, you can successfully complete this project on your own or assist a professional. Here is a comprehensive guide on how to remove a submersible pump effectively.

Understanding Your Submersible Pump

Before you begin, it’s important to understand the components of a submersible pump. These pumps are designed to function underwater, and they consist of a motor, impeller, and pump casing. They are usually installed in wells to draw water from underground sources. Understanding how your specific pump is installed will make the removal process smoother.

Safety First

Safety should always be your first priority when working with electrical equipment and heavy machinery. Before you start, wear appropriate safety gear, including gloves and safety glasses. Ensure that the power to the pump is completely turned off at the circuit breaker to prevent any electrical hazards. It’s also advisable to have a friend or neighbor nearby for assistance.

Gather Your Tools

You will need several tools for this task, including

- A wrench or socket set - Pliers - A screwdriver (flathead and Phillips) - A utility knife - A hoist or come-along (for lifting the pump) - A bucket or container (to catch any water that may spill)

Having the right tools on hand will help you work more efficiently.

Steps to Remove the Submersible Pump

1. Check the Ground Surface Ensure that the area where you will be working is stable and free from any obstructions. The last thing you want is to trip or fall while handling equipment.

2. Disconnect the Power Supply Locate the electrical panel and turn off the breaker that supplies power to the pump. This step is crucial to avoid electrical shocks during the removal.

3. Remove the Well Cap If your pump is located in a well, you’ll need to remove the well cap. Use a screwdriver to unscrew the well cap carefully. Make sure to keep track of all screws and components for reinstallation later.

4. Disconnect the Wiring Gently pull up on the electrical wires connected to the pump while making sure to avoid damaging them. Depending on your installation, the wiring may be enclosed within a junction box. If so, detach the box using your screwdriver before proceeding.

5. Detach the Discharge Pipe The pump will be connected to a discharge pipe. Using a wrench, loosen the fittings that connect the pipe to the pump. Be prepared for some residual water to spill out when you disconnect this pipe.

6. Prepare for Pump Extraction Once the electrical and plumbing connections are removed, you can start preparing to lift the pump out of the well. Use a hoist or a come-along to attach securely to the pump. Ensure all connections are tight and the hoist is positioned correctly to prevent any accidents.

7. Lift the Pump Slowly begin to lift the pump out of the well. Make sure to maintain a steady pace and never jerk or pull suddenly, as this could damage the pump or the well casing. Keep the area clear of any unnecessary personnel during this process.

8. Inspect the Pump After successfully removing the pump, take the time to inspect it for any damage or wear. This will help determine if it can be repaired or if a new pump is necessary.

Reinstallation or Disposal

Once you have removed the pump, you can decide whether to reinstall, repair, or dispose of it. If you need to reinstall, the steps will be the reverse of removal. Make sure all connections are secure and test the pump after installation to ensure it functions properly.

Conclusion

Removing a submersible pump from a well requires careful preparation, safety precautions, and the right tools. By following the steps outlined in this guide, you can effectively remove a submersible pump and either repair or replace it as needed. If you feel uncomfortable with any part of the process, don’t hesitate to consult a professional well contractor for assistance.
