How to Change a Submersible Well Pump


Changing a submersible well pump can seem daunting, but with the right tools and approach, it can be a manageable task. Submersible pumps are typically found in deep wells, submerged underwater to pump water to the surface. Over time, these pumps can fail due to wear and tear, improper installation, or electrical issues, necessitating a replacement. Here’s a step-by-step guide on how to change a submersible well pump safely and effectively.


Gather the Necessary Tools and Materials


Before you begin, ensure you have all the required tools and materials on hand. This typically includes


- A new submersible well pump - Wrenches (adjustable and socket) - Pliers - A sturdy rope or cable - Buckets or a pump hoist - A voltage tester - Pipe thread tape - Safety gloves and goggles - A level and a measuring tape


Safety First


Before doing any work on your well pump, ensure safety is your top priority. Turn off the power to the well pump at the circuit breaker to avoid any electrical accidents. It’s also a good idea to wear gloves and goggles to protect yourself from debris and sharp objects.


Remove the Old Pump


1. Access the Well Locate the well casing, which is typically a round, vertical cylinder that houses the pump and piping. Remove the protective cover.


2. Disconnect the Power Supply Use a voltage tester to double-check that power is off before proceeding.


3. Pull the Pump Connect a rope or cable to the pump for easy retrieval. Gently tug on the pump while ensuring the wiring and pipes do not get snagged or damaged as you pull it out. Depending on the size and depth of the well, you may need assistance for this step.

4. Disconnect the Pump Once the pump is at the surface, disconnect the electrical wires and any plumbing connections. Be sure to note how everything is connected, as you’ll need to replicate this when installing the new pump.


Install the New Pump


1. Prepare the New Pump Before lowering the new pump into the well, apply pipe thread tape to the connections to ensure a tight fit and prevent leaks.


2. Reconnect Electrical Wiring Follow the notes or diagram you took during the removal process to connect the electrical wires appropriately.


3. Lower the Pump Gently lower the new pump into the well while carefully ensuring that the piping and electrical cables do not twist or kink.


4. Secure Connections Once the pump is at the desired depth, secure all plumbing connections tightly.


Restore Power and Test the System


After securing the pump and connections, restore power at the circuit breaker. Turn on the well pump and monitor for any unusual sounds or leaks. Check the water flow at the nearest faucet to ensure everything is functioning correctly.


Conclusion


Changing a submersible well pump is a task that requires careful planning and execution. While it can be physically demanding, ensuring safety and precision will help you successfully replace your pump. If you feel uncertain or uncomfortable during any part of the process, it's wise to consult a professional plumber or well technician. A properly functioning well pump is essential for a reliable water supply, so invest the time to do it right.
