How to Pull a Submersible Water Well Pump
Submersible water well pumps are integral components for residential and agricultural water systems, providing a reliable source of groundwater. However, there may come a time when the pump needs to be pulled out for maintenance, repairs, or replacement. This guide will help you understand the step-by-step process of pulling a submersible well pump safely and efficiently.
Understanding Submersible Water Well Pumps
A submersible well pump is designed to be submerged underwater. Unlike other types of pumps, which operate above ground, these pumps are installed deep within the well casing and are encased in a waterproof housing. They are equipped to lift water from depths that other pumps cannot reach, making them ideal for deep well applications.
Safety First
Before beginning the process, ensure you have the right tools and safety equipment. Personal protective equipment (PPE) such as gloves, goggles, and steel-toed boots can protect you from potential hazards. Additionally, having a helper or assistant can make the job more manageable, especially during the lifting process.
Tools and Equipment Needed
1. Wrenches and Pliers To disconnect any fittings. 2. Cable Wrench Specifically designed for pulling submersible pumps. 3. Rope or Chain Hoist To help lift the pump out of the well. 4. Bucket and Crate To place the pump on once it’s out of the well. 5. Flathead and Phillips Screwdrivers For any small components that need removal. 6. Measuring Tape To check the depth of the pump in the well.
Step-by-Step Process
1. Turn Off Power Always begin by turning off the electrical supply to the pump. It’s critical to avoid any electric shock or injury during the process.
2. Disconnect Fittings Remove the access panel and disconnect the pipes, wiring, and any other connections between the pump and the water system. Use a wrench to loosen fittings carefully.
3. Assess the Pump’s Depth Measure how deep the pump is situated within the well. This can help gauge the length of wire and rope needed for pulling it out.
4. Attach the Pulling Cable Securely attach the pulling cable to the top of the pump. Ensure it is firmly connected to prevent slippage during extraction.
5. Begin Pulling the Pump With the assistance of a hoist or a helper, gently start pulling the pump upwards. It may be necessary to alternate pulling and releasing to free the pump from any debris or sediment that may be lodged around it.
6. Lift the Pump Out Once the pump is free, carefully lift it out of the well. It’s important to maintain even pressure to avoid damaging the pump.
7. Place on Stable Surface Once out, place the pump on a stable, clean surface, such as a crate or bucket, to inspect it thoroughly.
8. Check for Damage Before reinstallation or replacement, assess the pump for any signs of wear, damage, or mineral buildup, which could indicate the need for repair or cleaning.
Conclusion
Pulling a submersible water well pump may seem daunting, but with the right tools, proper safety precautions, and a step-by-step approach, it can be done effectively. Whether you're performing routine maintenance or replacing an old unit, understanding this process is essential for any well owner. Always consider calling a professional if you feel uncertain at any step, ensuring the job is done safely and correctly.
