How Do I Pull a Submersible Well Pump?
Pulling a submersible well pump can seem like a daunting task, but with the right preparations and tools, it can be accomplished effectively. Submersible pumps are designed to operate underwater, typically located in boreholes or wells, where they pump water to the surface. Over time, these pumps can fail or require maintenance, necessitating their removal. Here’s a detailed guide on how to pull a submersible well pump safely and efficiently.
Tools and Equipment Needed
Before you start the process, gather all the necessary tools and equipment. You will require
1. Wrenches Adjustable wrenches and socket wrenches to loosen and tighten various fittings. 2. Rope or Cable A strong rope or cable to lift the pump. Ensure it can support the weight of the pump. 3. Pry Bar To help dislodge the pump if it is stuck. 4. Safety Gear Gloves, goggles, and a hard hat for personal safety. 5. Pulley System (optional) For larger pumps, a pulley system can help ease the lifting process. 6. Bucket or Hose To drain water from the well if necessary.
Steps to Pull a Submersible Well Pump
1. Safety First Before starting, ensure that the power to the pump is turned off. This is crucial to avoid electric shock or injury. Additionally, check for any nearby power lines or obstacles that may pose a danger.
2. Remove the Cap Most wells have a cap on top that protects the pump and tubing. Remove this cap carefully using a wrench.
3. Disconnect the Electrical Wires Note how the electric wires are connected to the pump. It’s advisable to take a photo or label them for easy reconnection later. Disconnect the wires using a wrench or pliers to loosen the connectors.
4. Attach the Rope or Cable Securely attach your rope or cable to the pump. Make sure it’s tightly secured to prevent slippage during the lifting process.
5. Check the Pump’s Position If the pump is stuck, use a pry bar to gently dislodge it. Be cautious not to damage the pump or the well casing.
6. Lifting the Pump Slowly and carefully begin to pull the pump straight out of the well. If you encounter resistance, stop and assess the situation to avoid damaging the pump or well components. If you are using a pulley system, ensure that it is functioning properly to distribute the weight evenly.
7. Remove the Pump Once the pump is free of the well, gently pull it to the surface. This may require coordination if you’re working with a team—ensure everyone is aware of the plan.
8. Inspect and Maintain After successfully pulling the pump, take the time to inspect it for damage, wear, or obstruction. Cleaning and maintaining the pump can prolong its life and improve performance.
9. Reinstallation If you are reinstalling the pump, reverse the removal process. Make sure all electrical connections are secure and that the pump is seated properly in the well.
10. Restore Power Once everything is reassembled, restore power to the pump and test it to ensure it’s functioning correctly.
Conclusion
Pulling a submersible well pump doesn’t have to be an overwhelming task if approached methodically. By following these steps and prioritizing safety, you can successfully remove and inspect your pump when needed. Whether performing routine maintenance or addressing a malfunction, being prepared and knowledgeable will make the process much smoother. Always remember that if you feel uncertain at any stage, seeking professional assistance is a wise decision to ensure both safety and efficiency.
