How to Install a Submersible Deep Well Pump

Installing a submersible deep well pump can seem daunting, but with the right preparation and tools, you can accomplish this task successfully. A submersible pump is used to draw water from deep underground sources, making it ideal for agricultural, residential, or commercial uses. Below is a step-by-step guide to help you through the installation process.

1. Gather the Necessary Materials and Tools

Before you begin the installation, it's important to gather all necessary materials and tools. You will need - A submersible deep well pump - A drilling rig or a well casing pipe - Electrical wiring and connectors - A discharge head - A torque arrestor - PVC piping or poly tubing - A well cap (if applicable) - A wrench and a screw driver - A level or measuring tape Make sure to choose a pump that is appropriately sized for your well depth and the volume of water you need.

2. Prepare Your Well

Ensure that your well casing is clean and free from debris. If this is a new well, make sure it has been properly drilled and is ready for pump installation. Clear any obstructions in the well that might block the pump from being lowered.

3. Assemble the Pump

Start by assembling the pump according to the manufacturer’s instructions. This usually involves attaching the motor to the pump housing and securing it properly. Make sure that all O-rings and seals are intact to prevent water leaks.

4. Attach the Drop Pipe

Connect the pump to the drop pipe, which will carry water from the pump up to the surface. Use PVC or poly tubing to create a secure connection. It’s advisable to use threaded joints so that you can easily disconnect the pipe if maintenance is needed in the future.

5. Install the Torque Arrestor

A torque arrestor is crucial because it prevents the pump from spinning in the well casing as it operates. It also helps stabilize the pump in the well. Install it according to the manufacturer’s instructions, typically several feet above the pump, secured to the well casing.

6. Lower the Pump into the Well

Carefully lower the complete assembly (pump attached to drop pipe) into the well. Use a crane, pulley, or winch to avoid any injury or damage to the equipment. Ensure that the pump is at the appropriate depth, often set below the water level.

7. Connect Electrical Wiring

Once the pump is installed, it’s time to connect the electrical wiring. Follow local electrical codes and the manufacturer’s guidelines to ensure safety. Connect the pump wiring to your power supply, which may involve installing a control box above ground. Always make sure the power is turned off before handling electrical connections.

8. Install the Discharge Head

The discharge head is installed at the top of the well casing. This is where water will flow out, and it usually includes a check valve to prevent backflow. Follow the manufacturer's instructions to securely connect it to the drop pipe.

9. Test the Installation

Before sealing the well, turn the power back on to test the pump. Check for leaks around the connections and ensure that the water flow is consistent. It may take a few minutes for the pump to prime, so be patient.

10. Finalize and Seal

After confirming that everything is working correctly, seal the well cap and ensure that all connections are secure. This will help to prevent contamination and protect your pump from the elements.

Conclusion

Installing a submersible deep well pump requires careful planning and execution. By following the steps outlined above, you can ensure a smooth installation process. Always prioritize safety and follow local regulations and guidelines for well installations. With your pump in place, you’ll have reliable access to the water you need.
