Guidelines for Safely Removing Submersible Well Pumps from Water Sources

Removing Submersible Well Pumps A Comprehensive Guide


Submersible well pumps are crucial components in many water supply systems, particularly in residential and agricultural settings. They are designed to operate underwater, pushing water to the surface through a series of connected pipes. However, there are instances when you may need to remove a submersible well pump—such as for repair, maintenance, or replacement. This article provides a comprehensive guide to safely and effectively removing a submersible well pump.


Understanding Submersible Well Pumps


Before diving into the removal process, it's imperative to understand how submersible well pumps operate. These pumps are typically located deep within a well casing, submerged in water, making them highly efficient at lifting water to ground level. The pump itself consists of a motor, impellers, and other components housed in a waterproof casing. This design allows for continuous operation while minimizing the chances of cavitation and overheating.


Tools and Equipment Needed


To ensure a smooth removal process, you'll need several tools and equipment 1. Wire Cutters For disconnecting electrical leads. 2. Wrenches To loosen and remove bolts securing the pump. 3. Pipe Wrench Essential for gripping and unscrewing the discharge pipe. 4. Hoisting Equipment A pulley system or well pump puller to lift the pump out of the casing. 5. Safety Gear Gloves, safety glasses, and hard hats to ensure personal safety during the removal.


Step-by-Step Removal Process


1. Prepare the Site Clear the area around the well to ensure there is enough space to work. Remove any obstructions that could impede the removal process.


2. Turn Off Power Before any work begins, turn off the power supply to the pump at the circuit breaker. It's crucial to ensure the pump is completely de-energized to avoid electric shock.

3. Disconnect Electrical Connections Using wire cutters, carefully cut the electrical connections to the pump. Take note of where each wire connects, as you will need to reconnect them later. Labeling the wires can facilitate this process.


4. Unscrew the Discharge Pipe Using a pipe wrench, carefully unscrew the discharge pipe that connects the pump to the surface plumbing. Be cautious as residual water may drip out during this process.


5. Attach Hoisting Equipment If your pump is heavy, it’s essential to use hoisting equipment. Attach a well pump puller or a sturdy lifting cable securely to the pump. Ensure that the hoisting equipment can bear the weight of the pump to prevent accidents.


6. Pull the Pump Gradually lift the pump out of the well casing. Keep the pulling line straight to avoid binding the pump. If you encounter resistance, stop and assess the situation to avoid damaging the pump or the well casing.


7. Inspect the Pump Once the pump is out, take time to inspect it for signs of wear or damage. This is an excellent opportunity to perform maintenance tasks like cleaning or replacing worn parts.


8. Store Properly If the pump is to be stored, ensure it is cleaned and dried properly to prevent corrosion or damage while not in use.


Conclusion


Removing a submersible well pump is a task that requires careful planning and execution. By following the steps outlined above and using the proper tools, you can ensure a safe and efficient removal process. Always prioritize safety, and when in doubt, consider consulting with a professional well service technician, especially if the pump's removal becomes complicated. Regular maintenance of your submersible well pump can extend its lifespan and ensure a reliable water supply for your needs. Properly carried out, pump removal is a manageable process that, with practice and knowledge, can save homeowners time and money.
