Steps for Safely Removing a Deep Well Submersible Pump from Your Water Well System

How to Pull a Deep Well Submersible Pump


Deep well submersible pumps are essential for extracting groundwater from deep aquifers. These pumps are typically submerged in water and are designed to operate in extreme conditions, but there may come a time when you need to pull a submersible pump for maintenance, repair, or replacement. In this article, we will guide you through the steps involved in pulling a deep well submersible pump safely and efficiently.


Safety First


Before beginning any work on a submersible pump, it’s crucial to prioritize safety. Make sure to wear appropriate personal protective equipment (PPE), such as gloves, safety glasses, and hard hats. If you're working with electricity, ensure that the power to the pump is turned off to prevent any electrical hazards.


Gather Necessary Tools


To pull the pump, you'll need several tools, including


1. A hoist or a crane Depending on the pump's size, a manual or electric hoist may be required. 2. A wrench set This will be helpful for disconnecting various fittings. 3. Pipe wrenches Used to grip and turn the pipes connected to the pump. 4. Slings or straps To securely lift the pump. 5. A well casing brush To clean the well casing, if necessary.


Prepare the Work Area


Before you start the process, clear the area around the well to ensure that no obstacles will interfere with pulling the pump. If the pump is located in a pit, make sure to have adequate drainage and space to work safely.


Disconnect Power Supply


Locate the electrical control box that powers the submersible pump. Disconnect or turn off the circuit breaker to ensure there is no power flowing to the pump during the disconnection process. Verify that the pump is off by checking with a multimeter or test light.


Remove the Well Cap

If the pump is installed in a well casing, the next step is to remove the well cap or cover. This will give you access to the drop pipe, which connects the pump to the surface. Be careful while removing the cap to prevent any debris from falling into the well.


Disconnect the Drop Pipe

Depending on your pump's installation, you may need to disconnect the pipe fittings and any other connections at the top of the well. Use pipe wrenches to carefully loosen the fittings, taking care not to damage them, which could complicate the reinstallation process.


Lift the Pump


Attach the hoisting equipment to the top of the drop pipe. Ensure that the lift is secure and stable before lifting. Slowly begin to pull the pipe out of the casing, keeping an eye on the pump to ensure it remains level as it is pulled upward. This is crucial; tilting the pump can damage its casing or the well itself.


Inspect and Maintain


Once the pump is out, take the opportunity to clean it, inspect for wear, and conduct any necessary maintenance or repairs. Look for signs of damage, wear, or corrosion, and replace any worn-out components as needed.


Reinstallation


When you’re ready to reinstall the pump, simply reverse the steps you took to remove it. Connect the drop pipe, secure all fittings, and reattach the well cap. Make sure to test the system before sealing everything back up to ensure it’s functioning correctly.


Conclusion


Pulling a deep well submersible pump may seem challenging, but with the right preparation, tools, and safety measures, it can be accomplished effectively. Regular maintenance and inspections of your submersible pump system can extend its lifespan and enhance its efficiency, ensuring reliable access to the water you need.
