How to Pull a Submersible Well Pump
Extracting a submersible well pump is a task that requires careful planning and the right equipment. Whether you need to repair, replace, or inspect the pump, understanding the process can save you time and effort. Here’s a step-by-step guide on how to pull a submersible well pump effectively.
1. Safety First
Before beginning the extraction process, ensure you have the necessary safety gear. This typically includes gloves, safety goggles, and sturdy footwear. It’s also important to turn off the power supply to the pump to prevent any accidents.
2. Gather Tools and Equipment
You will need specific tools to pull a submersible well pump. Common tools include a pipe wrench, a well-winch, pliers, and a riser pipe puller. If the pump is particularly deep, a suitable winching system, like a tripod or A-frame hoist, may be necessary. Make sure everything is in good working condition.
3. Disconnect the Components
Start by removing the well cap that sits on top of the well casing. Once removed, disconnect the electrical wiring connected to the pump. Take care to label wires if necessary, as this will make reconnection easier later on.
Using your pipe wrench, carefully unscrew the discharge head or fitting from the pump, releasing any fittings attached to the riser pipe. If your pump uses a check valve, ensure it is handled carefully to avoid damage. Once discharged, attach the lifting mechanism to the pump’s casing.
5. Pull the Pump
With the lifting mechanism in place, slowly pull the pump out of the well. It is crucial to do this in a steady, controlled manner to avoid damaging components. If you encounter resistance, do not force it; check for any remaining connections that may not have been detached.
6. Inspect and Clean
After successfully pulling the pump, inspect it for any signs of wear or damage. Clean any debris or sediment from the pump and well casing. If repairing or replacing parts, consider checking the entire system for any issues.
7. Reinstallation
If reinstallation is necessary, follow the reverse steps of disassembly, ensuring every connection is secure and the wiring is appropriately reconnected.
Pulling a submersible well pump requires patience and attention to detail. By following these steps, you can successfully complete the task and ensure your water supply system remains functional. Always consult a professional if you’re unsure or encounter challenges during the process.
