Submersible Well Pump Removal Tool: A Comprehensive Guide

Submersible well pump removal tools are specialized devices designed to facilitate the extraction of submersible pumps from wells. These tools are crucial for well maintenance, repair, or replacement tasks, ensuring a safe and efficient process. While the search results do not provide specific technical specifications for submersible well pump removal tools, they offer valuable insights into the process and requirements of removing a submersible well pump.

Pitless Adapter: The Key to Successful Removal

One key aspect of submersible well pump removal is the pitless adapter, a critical component that connects the well casing to the water pipeline. Pitless adapters come in various types, each requiring specific tools or techniques for removal. For instance, a pitless adapter wrench, typically a 1″ piping piece that screws into the top of the adapter, may be needed for certain adapter types, allowing for easy removal.

Types of Pitless Adapters

1. Threaded Pitless Adapter: This type of adapter is threaded directly into the well casing, requiring a specialized wrench for removal. The wrench is typically a 1″ pipe that screws into the top of the adapter, providing the necessary leverage to unscrew it.

2. Bolt-on Pitless Adapter: This adapter is secured to the well casing using bolts, which can be removed using a socket wrench or other appropriate tools.

3. Clamp-on Pitless Adapter: This adapter is held in place by a clamp mechanism, which can be released using specialized pliers or a clamp-on pitless adapter tool.

4. Slip-on Pitless Adapter: This type of adapter simply slips over the well casing, often secured with a set screw. Removal may involve loosening the set screw and gently pulling the adapter off the casing.

Identifying the specific type of pitless adapter in your well is crucial for selecting the appropriate removal tool or technique.

Safety First: Rope or Cable Attachment

Another critical factor in submersible well pump removal is the presence of a rope or cable attached to the pump. This safety measure ensures that if the pump is accidentally dropped during the removal process, it can still be retrieved from the narrow well hole. The importance of having a rope or cable cannot be overstated, as breaking the pump off could result in thousands of dollars in repair costs.

Rope or Cable Specifications

1. Rope Material: The rope or cable used should be made of durable materials, such as nylon or polypropylene, to withstand the weight of the submersible pump and any potential strain during the removal process.

2. Rope Diameter: The rope or cable should be thick enough to support the weight of the submersible pump, typically ranging from 1/2″ to 3/4″ in diameter.

3. Rope Length: The rope or cable should be long enough to reach the bottom of the well, with additional length to allow for easy handling and retrieval during the removal process.

4. Rope Strength: The rope or cable should have a tensile strength that exceeds the weight of the submersible pump, ensuring a safe and secure attachment.

Ensuring the presence and proper specifications of the rope or cable attached to the pump is a critical safety precaution during the submersible well pump removal process.

DIY Submersible Well Pump Removal: A Step-by-Step Guide

When it comes to the DIY removal of a submersible well pump, the process involves several key steps:

1. Identify the Pitless Adapter Type: The pitless adapter is typically located about 5 feet down the well casing and can be inspected with a flashlight. Determine the specific type of adapter to select the appropriate removal tool or technique.

2. Gather the Necessary Tools: Depending on the pitless adapter type, you may need a pitless adapter wrench, socket wrench, pliers, or other specialized tools to facilitate the removal process.

3. Disconnect the Electrical Connections: Safely disconnect the electrical wiring and cables connected to the submersible pump, ensuring the power supply is turned off.

4. Detach the Pitless Adapter: Using the appropriate tool or technique, carefully detach the pitless adapter from the well casing. This may involve unscrewing, unbolting, or releasing the clamp mechanism, depending on the adapter type.

5. Retrieve the Pump: Gently pull the submersible pump out of the well, using the attached rope or cable to guide and support the pump during the removal process.

6. Inspect and Maintain the Pump: Once the pump is removed, thoroughly inspect it for any damage or wear and perform necessary maintenance or repairs before reinstalling it or replacing it with a new pump.

By following these steps and using the appropriate tools and techniques, you can safely and effectively remove a submersible well pump from your well, ensuring the continued reliable operation of your water supply system.

Specialized Submersible Well Pump Removal Tools

While the DIY approach can be effective, there are also specialized submersible well pump removal tools available on the market that can simplify the process and provide additional benefits:

Pitless Adapter Wrenches

Pitless adapter wrenches are designed specifically for removing threaded pitless adapters. These wrenches typically feature a 1″ pipe that screws into the top of the adapter, providing the necessary leverage to unscrew it. Some pitless adapter wrenches may also have additional features, such as a built-in ratchet mechanism or a longer handle for increased torque.

Clamp-on Pitless Adapter Tools

For clamp-on pitless adapters, specialized tools are available that can release the clamp mechanism, allowing for easy removal of the adapter. These tools often resemble pliers or clamps and are designed to fit the specific dimensions of the clamp-on adapter.

Pump Extraction Tools

Pump extraction tools are designed to grip the submersible pump securely and provide a mechanical advantage for lifting it out of the well. These tools may feature a clamping mechanism, hooks, or other specialized features to ensure a secure hold on the pump during the removal process.

Rope and Cable Accessories

In addition to the rope or cable attached to the pump, there are various accessories available to assist in the removal process, such as:
– Rope or cable reels: These devices allow for the controlled and organized retrieval of the rope or cable during pump removal.
– Rope or cable grippers: These tools help maintain a secure grip on the rope or cable, preventing it from slipping during the removal process.

By utilizing specialized submersible well pump removal tools, you can streamline the removal process, improve safety, and reduce the risk of damage to the pump or well components.

Conclusion

Submersible well pump removal is a critical task that requires careful planning, the right tools, and a focus on safety. By understanding the various types of pitless adapters, the importance of rope or cable attachment, and the step-by-step DIY removal process, you can effectively and efficiently remove a submersible well pump from your well. Additionally, the availability of specialized removal tools can further simplify the process and provide added benefits. With the right knowledge and tools, you can ensure the successful maintenance, repair, or replacement of your submersible well pump, keeping your water supply system running smoothly.
