How to Pull a Submersible Well Pump A Step-by-Step Guide

Submersible well pumps are essential devices used to extract groundwater from deep wells. While these pumps are designed for durability and long-term use, there may come a time when you need to pull one for maintenance, replacement, or other reasons. Although this task can seem daunting, with the right tools, preparation, and guidance, it can be accomplished efficiently. Here’s a comprehensive step-by-step guide on how to pull a submersible well pump.

Tools and Equipment Needed

Before you start, gather the following tools

1. Wrench Set For disconnecting pipes and fittings. 2. Pump Hoist or Winch To safely lift the pump from the well. 3. Pulleys For guiding the hoisting line. 4. Safety Gear Gloves, safety goggles, and a hard hat. 5. Screwdrivers For unscrewing any electrical connection covers. 6. Pipe Cutters In case you need to cut pipes. 7. Garden Hose To flush the well if needed before pulling the pump. 8. Electrical Tester To ensure safe disconnection of power. 9. Ladder If the well casing is high, for safe access.

Step-by-Step Process

1. Turn Off the Power

The first and most crucial step is to ensure your safety. Locate the circuit breaker that powers the well pump and turn it off. Use an electrical tester to double-check that there is no current flowing to the pump and related control systems.

2. Remove the Well Cap

Once the power is off, remove the well cap carefully. This cap is typically secured with screws or bolts. Since the cap protects the well from contaminants, make sure to keep it clean while it's removed.

3. Disconnect Electrical Connections

With the well cap off, you'll see the wiring that connects your pump to the power source. Carefully disconnect these wires, taking note of where each one goes. If you’re unsure, take pictures for reference during reassembly.

4. Detach the Top of the Pump

Next, locate the discharge head of your submersible pump, which is typically attached to the well casing. Use the wrench to remove any fittings securing the discharge head to the casing. Make sure to catch any residual water in a bucket to avoid spills.

5. Set Up the Hoisting System

Attach the pump hoist or winch securely to the pump discharge. If you have a pulley system, set it up to help guide the pump upward. Ensure that everything is secured before starting the lift.

6. Begin Pulling the Pump

Once everything is ready, begin to lift the pump slowly and steadily. Go at a controlled pace to avoid putting unnecessary strain on the pump or its components. It's essential to keep the cable, pipe, and any hoses from kinking or twisting.

7. Inspect the Pump and Components

As you pull the pump out, take the time to inspect it for any signs of wear or damage. Check the wiring, impeller, and other components for wear. If the pump is clogged or damaged, you may need to troubleshoot the issue before reinstallation.

8. Perform Necessary Maintenance or Replacement

After pulling the pump, you can either perform maintenance or replace it entirely if required. Cleaning the pump, replacing seals, or servicing the motor can extend the lifespan of your pump.

9. Reinstallation

Once you address any issues, reinstalling the pump follows the opposite of the removal process. Ensure all connections are secure, both mechanical and electrical, and carefully lower the pump back into the well.

10. Check for Proper Operation

After everything is back in place, restore power to the pump. Listen for any unusual noises and monitor the flow of water. It’s critical to ensure that your pump is functioning correctly before fully reassembling the well cap.

Conclusion

Pulling a submersible well pump requires careful planning and attention to safety. While this guide provides a basic framework, each well system can vary, so always consult the manufacturer’s manual for specific instructions. If you feel uneasy about any part of the process, don’t hesitate to contact a professional. Proper maintenance and timely intervention can extend the life of your submersible well pump, ensuring reliable access to groundwater whenever you need it.
