How to Install a Submersible Water Well Pump

Installing a submersible water well pump can be a rewarding DIY project for those with some plumbing and electrical experience. These pumps are designed to be submerged in water, making them ideal for drawing water from deep wells. Here's a step-by-step guide on how to install one.

Step 1 Gather Necessary Materials

Before starting, ensure you have all the necessary materials. You will need a submersible pump, a well casing, electrical wiring, a control box, a discharge pipe, pipe fittings, a check valve, a well casing adapter, and basic tools like a wrench, tape measure, and pliers. It's also advisable to have a helper due to the weight of the pump.

Step 2 Prepare the Well

Safety is paramount. First, turn off the power supply to the existing pump, if applicable. Remove any debris from the well casing and ensure that the casing has the proper diameter for your new pump. Measure the depth of the well and the water level, as you'll need this information to select the right length of electrical wire and discharge pipe.

Step 3 Assemble the Pump

Follow the manufacturer's instructions to assemble the pump. Attach the discharge pipe to the pump outlet, ensuring all connections are secure. Install a check valve to prevent backflow and water hammering, which can damage the pump.

Step 4 Lower the Pump into the Well

With the help of a friend, carefully lower the assembled pump into the well casing. Ensure that the discharge pipe remains vertical as you descend the pump. It's essential to lower the pump to the proper depth, typically a few feet above the water source to avoid sand and debris intake.

Step 5 Connect Electrical Wires

Once the pump is in place, it's time to connect the electrical wiring. This can be dangerous, so ensure that the power is off. Use waterproof connectors to attach the pump wires to the electrical supply wire that runs to the control box. If you're unsure about the electrical connections, it's best to consult a professional electrician.

Step 6 Test the System

After completing the electrical connections, restore power to the pump. Turn on the control box and check for any leaks in the discharge line. Allow the pump to run for a few minutes, watching for adequate water flow and confirming the pump’s functionality.

Conclusion

Installing a submersible water well pump requires careful planning and execution. By following these steps, you can successfully set up a reliable water supply for your home or property. Always prioritize safety and consider hiring professionals if you're uncertain about any aspect of the installation. Enjoy your new water well pump, and ensure regular maintenance for long-lasting performance!
