How to Install a Submersible Well Pump


Submersible well pumps are a common choice for extracting water from deep underground sources. Compared to traditional pumps, submersible pumps are efficient and designed to operate underwater, providing a reliable source of water for irrigation, drinking, and other applications. If you're considering installing a submersible well pump, it's important to follow a systematic approach to ensure that the installation process is successful and the system operates effectively. Here’s a step-by-step guide on how to install a submersible well pump.


1. Gather Required Tools and Materials


Before starting the installation, make sure you have all the necessary tools and materials at hand. You will need


- Submersible well pump - Drill with various bits - Pvc pipes and fittings - Electrical cable (appropriate gauge) - Deep cycle or submersible pump-rated wire connectors - Rope or cable to lower the pump - Safety gear (gloves, goggles) - Wrenches and pliers - Teflon tape


2. Prepare the Well


Before installing the pump, inspect the well casing. Ensure that it is clean and free from any debris. If there are any existing connections or older pumps, remove them carefully. You must also check that the well has sufficient water flow to support the pump you are installing. A well with low flow may not function effectively with a submersible pump.


3. Select the Right Pump


Choose a submersible pump that suits your needs, taking into account the depth of your well, the amount of water you need, and the distance the water needs to be pumped. Pumps are rated based on horsepower, flow rate, and total dynamic head (TDH). Make sure the pump you select meets the requirements for your specific well.


4. Install the Pump


With the proper tools and pump ready, it’s time to install it. Here are the steps to follow

- Assemble the Pump First, attach any necessary fittings to the pump, including a check valve, which prevents backflow, and a discharge head, which will direct water to the surface. - Prepare the Wiring Cut and prepare the electrical cable according to the length required to reach from the pump to the surface. Ensure that the wiring is suitable for submersible applications and meets local electrical codes. Connect the electrical cable to the pump, ensuring that the connections are secure and waterproof.


- Lower the Pump Using a rope or cable, carefully lower the pump into the well casing. Make sure that it is placed at the appropriate depth, generally at least 10 feet above the bottom of the well to avoid sand and sediment entry.


- Secure the Pump Once the pump is in position, secure it with additional clamps or hanging gear to prevent it from moving. Ensure the discharge head is above the well casing.


5. Connect Power Supply


Now it’s time to connect the power supply. Route the electrical cable from the pump to the surface, where it will connect to the pressure switch and circuit breaker. Make sure to follow all local codes and regulations regarding electrical installations.


6. Test the System


After everything is connected, turn on the circuit breaker and test the pump. Allow it to run for a few minutes to ensure it is functioning correctly. Check for leaks and listen for abnormal noises which might indicate a problem.


7. Finalize Installation


Once the pump operates smoothly, finalize any remaining connections, ensure everything is secured, and cover the well casing properly.


Installing a submersible well pump may seem daunting, but by following these steps carefully, you can ensure a successful installation that will provide reliable water for your needs for years to come. If you encounter any complications during the process, don't hesitate to consult a professional for assistance.
