Accessing a consistent supply of clean water from your well is crucial for daily life. The heart of this system is often a high-quality submersible well pump. When it comes time for a new installation or a replacement, understanding the process is key to ensuring everything works correctly from the start. A proper installation prevents future headaches, costly repairs, and ensures your submersible water pump operates efficiently for years. This guide will walk you through the essential steps, from preparation to the final checks, providing the knowledge you need to tackle the installation of your submersible pump with confidence. Whether you're working with a new well or replacing an old unit, we will cover the critical details for a successful setup.
How do you set the stage for a smooth installation of your submersible pump? Proper preparation is not just a preliminary step; it's the foundation of a successful project. Rushing this phase can lead to significant problems down the line. Before you even think about lowering the submersible water pump into the well, you need to gather the right tools, confirm your well's specifications, and ensure all components are ready for assembly.
Do you have all the necessary equipment for the job? A well-organized workspace with every tool at your fingertips makes the installation process much safer and more efficient. Attempting to install a submersible utility pump without the right gear can result in damage to the pump or well casing.

Having these items ready prevents delays and ensures each connection is secure. Using the correct tools for tasks like splicing wires for the submersible pump is critical for creating a durable, waterproof seal.
What are your well's specific dimensions? Knowing the total depth of your well and the static water level is non-negotiable. The static water level is the distance from the ground to the water when the pump is not running. This information determines the proper placement depth for your submersible water pump. Placing the pump too high can cause it to run dry during periods of heavy use, while placing it too low can stir up sediment from the bottom of the well. You should position your submersible pump at least 10-20 feet below the static water level but also at least 5 feet from the bottom of the well.
How do you correctly assemble the components before lowering them into the well? This phase involves connecting the drop pipe, wiring, and safety rope to your new submersible pump. Each connection must be secure and waterproof to ensure the long-term reliability of the entire system. A faulty connection here could mean pulling the entire assembly back up for repairs.
What is the correct way to connect the piping? Start by threading a male adapter into the discharge port of the submersible water pump. Use Teflon tape on the threads to create a watertight seal. Next, attach the first section of the drop pipe to this adapter. If your submersible pump does not have a built-in check valve, you must install one directly above the pump. This valve prevents water from flowing back into the well when the pump shuts off, which protects the pump from damage and maintains pressure in the system. As you add sections of drop pipe, ensure each threaded connection is tight and sealed with Teflon tape.
Can you create a durable, waterproof electrical connection? The electrical splice is one of the most critical parts of the installation. A poor splice will fail, causing the submersible pump to stop working. Start by stripping the ends of the motor leads and the submersible pump cable. Using a high-quality waterproof splice kit, connect the wires, matching the colors correctly. Use crimp connectors to join the wires securely. After crimping, slide the heat-shrink tubing over the splices, ensuring it completely covers the connection. Use a heat gun to shrink the tubing, creating a permanent, waterproof seal that protects the wiring for your submersible pump from moisture.
How do you manage the wiring and safety rope? The safety rope is essential; it's your backup for retrieving the submersible water pump if the drop pipe ever breaks. Tie the rope securely to the designated eyelet on the top of the submersible pump using a strong knot that won't slip, like a bowline. As you lower the pump, you will need to secure the electrical cable and the safety rope to the drop pipe at regular intervals, typically every 10 feet. Use electrical tape or specialized cable guards to do this. This prevents the wire from getting tangled, abrading against the well casing, or wrapping around the submersible pump itself.
What is the safest method for lowering the pump assembly? With the submersible pump, drop pipe, wiring, and safety rope assembled, it's time for the most delicate part of the operation: lowering the unit into the well casing. This requires care and patience to avoid damaging the pump or the well.
How can you guide the assembly into the well without issues? Slowly and carefully lower the entire assembly into the well. It's often helpful to have another person assist you. One person can guide the pipe and submersible water pump into the well casing while the other helps manage the pipe, cable, and rope. Be careful not to let the pump bang against the sides of the casing. As you lower it, continue to secure the wire and safety rope to the drop pipe. Lower the submersible utility pump to your predetermined depth.
How do you make the final connections at the wellhead? Once the pump is at the correct depth, the next step is to connect the pitless adapter. This device creates a sanitary, frost-proof connection through the well casing below the frost line. Slide the pitless adapter's male fitting (attached to the drop pipe) into the female fitting mounted on the well casing wall. Once it locks into place, you can feed the electrical cable through the top of the well cap. Secure the well cap to the top of the casing, ensuring a tight, sanitary seal to prevent contaminants from entering the well. Finally, secure the safety rope to the wellhead.
What checks should you perform before finishing the job? With the submersible water pump in place, a few final steps are required to get your water system operational. This includes making the final electrical connections and testing the system to ensure everything is working as it should.
How are the final electrical connections made? The electrical cable from your submersible pump needs to be connected to the pressure switch and, if applicable, the pump control box. This work should be performed by a qualified electrician if you are not experienced with wiring. Turn off all power to the circuit at the breaker panel before you begin. Following the manufacturer's wiring diagram, connect the wires from the submersible utility pump to the correct terminals on the pressure switch. The pressure switch is what tells the pump when to turn on and off based on the pressure in your water tank.
Is your new submersible pump working correctly? Once all plumbing and electrical connections are complete, it's time to test the system. Turn the power back on. The submersible pump should start and begin filling the pressure tank. Check for any leaks at the wellhead, in the pressure tank, and at all plumbing connections. Let the pump run through a full cycle, observing the pressure switch as it turns the pump off at the cut-out pressure and back on at the cut-in pressure. Listen for any unusual noises from the pump. You should also open a faucet and check the water flow. The water may initially be cloudy with sediment, but it should clear up quickly.
Properly installing a submersible well pump is a detailed but manageable task that ensures your home has a reliable water source. From diligent preparation to careful assembly and final testing, each step is vital for the longevity and efficiency of your submersible pump system.

A submersible pump should be positioned at least 10-20 feet below the static water level to ensure it remains submerged, but also at least 5 feet from the bottom of the well to avoid pulling in sand, silt, or other sediment.
While it is possible for a person with strong mechanical and electrical skills to install a submersible pump, it is often a two-person job. Handling the weight of the pump and many feet of pipe can be difficult alone. If you are not confident in your ability to perform the electrical wiring safely, you should hire a qualified electrician.
The lifespan of a quality submersible water pump can vary depending on factors like water quality, usage, and correctness of installation. On average, you can expect a well-maintained submersible pump to last from 8 to 15 years.
Yes, a check valve is essential. Many submersible pump models come with a built-in check valve. If yours does not, you must install one directly above the pump. The check valve prevents water from flowing back down into the well when the pump turns off, which helps maintain pressure in your system and reduces wear on the pump motor.
