Step-by-Step Guide to Retrieve Your Submersible Pump from the Depths

Submersible pumps are essential components of many well systems, providing water for homes, businesses, and agricultural operations. However, when these pumps malfunction or need servicing, it becomes necessary to retrieve them from the well. This can be a daunting task, but with the right tools and techniques, it is possible to safely and efficiently remove a submersible pump from a well.

Tools and Equipment

Before attempting to remove a submersible pump from a well, it is crucial to gather the necessary tools and equipment. These include:

• Safety harness: For personal safety when working near the well.
• Pipe wrench: To loosen and remove the pump’s discharge pipe.
• Chain or rope: To lift the pump out of the well.
• Electrical disconnect: To safely disconnect the pump’s electrical supply.
• Flashlight: To illuminate the well interior.
• Buckets or pump: To remove water from the well if necessary.
• Measuring tape: To determine the depth of the pump.

Safety Precautions

Working with submersible pumps and wells can be hazardous. Always prioritize safety by following these precautions:

• Wear appropriate safety gear, including a hard hat, gloves, and safety glasses.
• Use a safety harness when working near the well.
• Ensure the well is properly ventilated to prevent exposure to harmful gases.
• Disconnect the pump’s electrical supply before handling it.
• If the well is deep or contains contaminated water, consider hiring a professional pump installer.

Steps to Remove a Submersible Pump from a Well

1. Disconnect Electrical Supply

Before starting any work, disconnect the pump’s electrical supply from the breaker panel. This will prevent electrical shock and potential damage to the pump.

2. Loosen Discharge Pipe

Locate the pump’s discharge pipe, which is typically connected to the well casing. Using a pipe wrench, carefully loosen the nuts or bolts securing the pipe to the pump.

3. Attach Chain or Rope

Tie a chain or rope securely around the pump’s lifting lug or bail. This will provide a means to lift the pump out of the well.

4. Remove Water from Well (Optional)

If the well contains a significant amount of water, it may be necessary to remove some of it to make the pump easier to lift. Use buckets or a pump to remove water until the level is below the pump.

5. Lift Pump Out of Well

Carefully lift the pump out of the well using the chain or rope. Use a steady, controlled motion to avoid damaging the pump or well casing.

6. Disconnect Wires

Once the pump is out of the well, disconnect the electrical wires from the pump. Be sure to label the wires for easy reconnection later.

7. Inspect Pump and Well

Inspect the pump for any damage or wear. Also, check the well casing for any damage or obstructions.

Troubleshooting

Pump is stuck in well:

• Ensure the discharge pipe is completely disconnected.
• Check if the pump is caught on any obstructions in the well.
• Try using a pry bar to gently dislodge the pump.

Pump is leaking water:

• Inspect the pump for any cracks or leaks.
• Replace any damaged seals or gaskets.
• Ensure the discharge pipe is properly connected and sealed.

Pump is not working:

• Check the electrical supply to ensure it is functioning.
• Test the pump using a multimeter to determine if it is receiving power.
• If the pump is not receiving power, check the electrical connections or replace the pump.

Reinstalling the Submersible Pump

Once the pump is out of the well and serviced or replaced, it is time to reinstall it. Follow these steps in reverse order:

1. Connect the electrical wires to the pump.
2. Lower the pump into the well using the chain or rope.
3. Connect the discharge pipe to the pump and tighten it securely.
4. Reconnect the pump’s electrical supply.
5. Test the pump to ensure it is working properly.

A Deeper Dive into Submersible Pump Removal

Understanding Submersible Pump Types

There are two main types of submersible pumps:

• Centrifugal pumps: Use rotating impellers to move water.
• Positive displacement pumps: Use pistons or diaphragms to move water.

The type of pump you have will determine the specific steps involved in removing it from the well.

Factors Affecting Pump Removal

Several factors can affect the difficulty of removing a submersible pump from a well:

• Well depth: Deeper wells require longer chains or ropes for lifting the pump.
• Pump weight: Heavier pumps may require additional assistance or equipment for lifting.
• Well casing size: Smaller well casings can make it more challenging to maneuver the pump.
• Well obstructions: Obstructions such as rocks or debris can hinder the removal process.

Alternative Methods for Removing Submersible Pumps

In some cases, it may be necessary to use alternative methods for removing a submersible pump from a well:

• Pulling with a winch: A winch can be used to pull the pump out of the well.
• Using a well jack: A well jack is a specialized tool designed for lifting submersible pumps.
• Hiring a professional: If you are not comfortable removing the pump yourself, consider hiring a professional installer.

Pumping Up Your Knowledge

By following these steps and precautions, you can safely and effectively remove a submersible pump from a well. Remember to prioritize safety, use the appropriate tools, and seek professional assistance if necessary. With the right knowledge and preparation, you can ensure a smooth and successful pump removal experience.

Frequently Asked Questions

Q: How often should I remove my submersible pump for maintenance?

A: The frequency of maintenance depends on the pump’s usage and water conditions. Generally, it is recommended to remove the pump every 2-5 years for inspection and servicing.

Q: What are the signs that my submersible pump needs to be replaced?

A: Signs of a failing submersible pump include reduced water flow, increased noise, or intermittent operation.

Q: Can I use a regular rope to lift a submersible pump?

A: No, do not use a regular rope to lift a submersible pump. Use a chain or rope specifically designed for lifting heavy objects from wells.
