How to Pull a Submersible Water Well Pump

Submersible water well pumps are essential components for extracting water from deep underground sources. While these devices are generally reliable, there may come a time when you need to pull the pump for maintenance, repair, or replacement. Pulling a submersible pump can seem daunting, but with the right tools and careful planning, it can be done safely and effectively. This guide will take you through the steps necessary to pull a submersible water well pump.

Safety First

Before beginning any work on a water well system, safety should be your top priority. Wear appropriate personal protective equipment (PPE), including gloves, safety glasses, and sturdy footwear. If you’re not familiar with working with electrical equipment, consider hiring a professional. Ensure that the electrical supply to the pump is turned off to avoid any risk of shock while disconnecting or handling the pump.

Tools and Equipment Needed

1. Wrench Adjustable or socket wrench. 2. Pipe Wrench For handling the well casing and discharge pipe. 3. Pulleys and Hoist If the pump exceeds typical lifting weights, consider using a hoist and pulley system. 4. Rope or Cable Strong enough to support the weight of the pump, usually nylon rope or steel cable. 5. Bucket For removing debris or water from the well. 6. Tackle Box or Storage Container For keeping small parts organized.

Step-by-Step Process

1. Turn Off Power Before starting the pulling process, ensure that the power to the pump is completely turned off. This may involve switching off a dedicated circuit breaker or removing a fuse.

2. Remove the Well Cap The well usually has a cap sealing off the top. Loosen and remove this cap to expose the well casing. Be careful not to drop anything into the well while you’re working.

3. Disconnect the Discharge Pipe Locate the discharge pipe at the top of the well. Use a wrench to disconnect any fittings or unions that connect the discharge pipe to the pump. Work carefully to prevent damaging any hoses or connections.

4. Prepare the Pump for Removal Once the discharge pipe is disconnected, you’ll need to attach your pulling equipment. Secure a rope or cable around the pump. If the pump has a built-in lifting eye, use that; otherwise, make sure the rope is tightly wrapped to avoid slippage.

5. Begin Pulling the Pump With the aid of your pulleys or hoisting system, start pulling the pump upwards slowly and steadily. It’s crucial to keep the pump vertical to avoid damaging the electrical wires or the pump itself. Make sure to communicate clearly with anyone helping you to ensure that everyone is coordinated.

6. Clear Debris As you pull the pump from the well, be vigilant for any debris that may need to be cleared. This includes sand, silt, or any obstructions that could hinder removal. A bucket may be useful at this stage for removing unwanted materials.

7. Inspect the Pump Once the pump is free, inspect it thoroughly. Look for signs of wear, damage, or sediment buildup. If you’re planning on reinstalling the pump, clean it accordingly and replace any worn components.

8. Replace or Repair Depending on your inspection results, either repair or replace the pump as necessary. Follow manufacturer guidelines and local regulations for reinstallation.

9. Reinstallation When re-installing the pump, reverse the removal process. Ensure that all connections are secure and, if applicable, test the pump before fully sealing the well cap.

10. Reconnect Power Once everything is securely in place and you’re sure the installation is correct, reconnect the power to the pump. Turn on the circuit breaker and listen for the pump to engage.

Conclusion

Pulling a submersible water well pump can be a straightforward task with the right tools, knowledge, and safety precautions. Always remember to prioritize safety, take your time, and if you're uncertain at any stage, don’t hesitate to contact a professional. Ensuring that your water well system is properly maintained will extend the life of your pump and keep your water supply running smoothly.
