How to Pull a Submersible Well Pump A Step-by-Step Guide
Pulling a submersible well pump may seem like a daunting task, especially for those who lack experience. Submersible pumps are vital components in many water systems, delivering water from deep underground to the surface for use in irrigation, drinking, and various other applications. Whether you're performing maintenance, inspecting the pump, or replacing it due to failure, following a systematic approach can make the process smoother and safer. This guide will walk you through the steps required to successfully pull a submersible well pump.
Tools and Safety Precautions
Before beginning, ensure you have the necessary tools and safety equipment. Common tools required include
- A wrench or socket set for disassembling fittings - A bucket or large container for holding the pump - A crane or winch system to assist in lifting - Protective gloves and eyewear - A fishing tape or rope can also be handy to pull up any connecting cables or hoses.
Always prioritize safety. Make sure to turn off the power supply to the pump before starting any work. This eliminates the risk of electric shock. Additionally, if the pump is located in a deep well, consider having a second person assist you.
Step 1 Disconnect Power and Water Supply
The first step in pulling a submersible pump is to disconnect the power source. Locate the circuit breaker connected to the pump and turn it off. Then, shut off the water supply to the pump if applicable. This prevents any water from entering the system while you are working.
Step 2 Remove the Well Head Cover
Next, remove the well head cover or access panel. Depending on the well's design, this may involve unscrewing bolts or simply lifting off a cover. Take caution when handling this component, as it can be heavy.
Step 3 Disconnect Plumbing and Electrical Lines
Once you have access to the pump, it is essential to detach any plumbing and electrical connections. Use the appropriate wrench to remove the bolts connecting the plumbing lines to the pump. Be prepared for water to spill out of the pipes, and have a bucket handy to catch any excess water.
Next, disconnect the electrical wires. Typically, these will be spliced and may be protected by a junction box. Carefully undo the wire nuts or screws and ensure that no copper wires are exposed.
Step 4 Prepare for Extraction
With all the connections removed, prepare to pull the pump from the well. If your pump is particularly heavy, you may want to use a pulley system or winch for additional support. Attach a sturdy lifting rope or cable to the pump securely.
Before lifting, check the surrounding area to ensure there are no obstacles. It’s crucial to have enough space to maneuver the pump as you pull it from the well.
Step 5 Pull the Pump Out
Carefully lift the pump from the well. This requires a steady and controlled motion. As you raise the pump, watch out for any snagging on pipes or cables. It’s important to keep the pump as vertical as possible to avoid damaging the components or wiring.
Step 6 Inspect and Maintain the Pump
After successfully removing the pump, take the time to inspect it thoroughly. Look for signs of wear and tear, corrosion, or any debris that may have entered the system. Cleaning and maintaining your pump can extend its lifespan and maintain efficiency.
Conclusion
Pulling a submersible well pump is a task that requires patience and safety precautions. By following the aforementioned steps, you can effectively pull your pump for maintenance or replacement. Whether you are a DIY enthusiast or a seasoned professional, this process can enhance your understanding and proficiency in well pump management. Remember, if you're ever in doubt, consulting a professional can ensure the job is done safely and correctly.
