How to Remove a Submersible Deep Well Pump

Removing a submersible deep well pump can seem like a daunting task, particularly if you are not familiar with the equipment or procedures involved. However, with careful planning and the right tools, you can efficiently accomplish this task, ensuring both your safety and the integrity of the pump. Below is a step-by-step guide to help you through the process.

Preparation

Before you begin, it is crucial to prepare adequately. Make sure you have all the necessary tools on hand, including a pipe wrench, adjustable wrenches, pliers, a bucket, a slotted screwdriver, and a hoist or well head puller if the pump is particularly heavy. Additionally, ensure that you have safety gear, including gloves and safety glasses.

Step 1 Turn Off the Power

Safety should always be your first priority. Locate the power supply to the pump and turn it off. This may involve switching off a circuit breaker or unplugging the pump from its power source. It is advisable to verify that the power is off by using a voltage tester. Do not skip this step, as working with live electricity poses a significant hazard.

Step 2 Disconnect the Pump

Carefully remove any protective coverings from the top of the well. You will usually find a well cap or a similar cover that serves as an access point. After removing this, locate the discharge pipe attached to the top of the pump. Using a pipe wrench, disconnect the piping. Be prepared for some residual water, so keep a bucket handy to catch any spills.

Once the discharge pipe is disconnected, you will need to remove the electrical wiring that powers the pump. Carefully untie the wiring from any clips or anchors that may be securing it to the well casing. If the wiring is hardwired, you may need to detach it from its junction box. Ensure you carefully note where each wire connects for reassembly.

Step 4 Prepare for Lifting

If your submersible pump is relatively lightweight, you might be able to lift it directly out of the well. However, many deep well pumps can weigh several hundred pounds. It is crucial to use a hoist or well head puller for heavy pumps. Make sure the lifting system is securely attached to the pump before proceeding. Additionally, check that the hoist or puller is suitable for the weight of your pump.

Step 5 Lift the Pump

With everything detached and your lifting system secured, begin pulling the pump out of the well slowly and steadily. Guide the pump as it rises, ensuring that no cables or pipes snag on the way up. Take your time to avoid any abrupt pulls that could damage the equipment or cause injury.

Step 6 Inspect the Pump

Once the pump is out, give it a thorough inspection. Look for any signs of wear and tear, clogs, or damage. This is an ideal time to perform maintenance or to replace the pump if needed. Clean any debris from the pump body and check the integrity of the wiring and discharge pipe before reinserting it.

Conclusion

Removing a submersible deep well pump involves several careful steps, but with the right tools and precautions, it can be done safely and effectively. Always prioritize safety, and when in doubt, consider calling in a professional. Regular maintenance and understanding of your equipment will make future jobs easier, ensuring a longer life for your pump.
