Having access to a private well is a significant advantage, providing a reliable source of fresh water independent of municipal systems. For wells that go deeper than 25 feet, a deep well water pump is essential to bring that water to the surface. Installing one can seem like a complex job, but with the right tools, knowledge, and a focus on safety, it's a project many homeowners can tackle.
This guide will walk you through the process of installing a deep well water pump. We'll cover everything from the initial preparations and safety checks to the step-by-step installation and final testing. By following these instructions, you'll be able to set up your water system correctly and ensure a consistent supply of water for your home.
Safety should always be your top priority. You will be working with heavy equipment, electrical components, and an open well, all of which present potential hazards. Before you start, gather the necessary tools and materials to ensure a smooth installation process.
· Turn Off the Power: The most crucial step is to completely shut off the power to the well pump at the main circuit breaker. Use a voltage tester to confirm there is no live current.
· Secure the Well Opening: Never leave the wellhead uncovered. An open well is a serious danger to people and animals. Keep it covered whenever you are not actively working on it.
· Work with a Partner: This is not a one-person job. The pump and pipe assembly can be very heavy and awkward to handle. A second person is essential for lifting, lowering, and preventing accidents.
· Wear Protective Gear: Always wear safety glasses and gloves. The work can involve sharp edges and debris.
Having all your tools ready will prevent delays and frustration. Here’s what you’ll likely need:
Tool/Material | Purpose |
|---|---|
New Deep Well Pump | The heart of your system. |
Pipe Wrenches (2) | For tightening and loosening pipe fittings. |
Screwdrivers | For electrical connections. |
Wire Strippers/Cutters | For preparing electrical wires. |
Teflon Tape | To seal threaded pipe connections and prevent leaks. |
Heat Shrink Splice Kit | To create waterproof electrical connections. |
Heat Gun | To apply heat to the shrink splices. |
Safety Rope | To support the weight of the pump during installation. |
Pitless Adapter Wrench | A special T-handle tool for the pitless adapter. |
Flashlight/Headlamp | For visibility inside the well casing. |
Voltage Tester | To confirm the power is off. |
With your safety checks complete and tools assembled, you can begin the installation. If you are replacing an old pump, the first step will be to remove it.
1.Disconnect Power: As mentioned, ensure the power is off.
2.Access the Wellhead: Remove the well cap to expose the pipes and wiring.
3.Disconnect Piping: Use your pipe wrenches to disconnect the pipe at the pitless adapter or wellhead connection.
4.Lift the Pump: With your partner, carefully begin lifting the old pump and pipe assembly out of the well casing. Pull hand over hand, laying the pipe out straight on the ground as it comes up. Be mindful of the electrical wires attached to the pipe.
5.Detach the Old Pump: Once the pump is out, cut the wires and detach it from the drop pipe.
1.Attach the Drop Pipe: Take your new pump and wrap the threads of its outlet with Teflon tape. Securely attach the first section of drop pipe using two pipe wrenches—one to hold the pump and one to turn the pipe.
2.Connect the Electrical Wires: Your new pump will have a short electrical lead. You need to splice this to the main submersible wire that will run to the surface.
3.
· Strip the ends of both the pump wires and the main submersible wire.
· Use the heat shrink splice kit to connect the corresponding wires (e.g., black to black, green to green).
· Use a heat gun to shrink the tubing over the splices, creating a durable, waterproof seal. This is critical to prevent electrical shorts.
4.Secure the Safety Rope: Tie the safety rope securely to the designated eyelets on the pump. This rope is a backup support system and is crucial for retrieving the pump if needed. Do not rely on the pipe or wire to hold the pump's weight.
1.Position the Pump: With your partner, carefully guide the new pump into the well casing.
2.Lower and Attach Pipe Sections: Lower the pump by the drop pipe and safety rope. As you lower it, attach additional sections of drop pipe, wrapping each threaded connection with Teflon tape and tightening securely with pipe wrenches.
3.Secure the Wires: Use electrical tape to secure the submersible wire to the drop pipe every 10-20 feet. This prevents the wire from getting tangled or damaged inside the casing.
4.Engage the Pitless Adapter: When you reach the correct depth, you’ll need to connect the pump assembly to the water line leading to your house.
5.
· Attach the male part of the pitless adapter to the top of the drop pipe.
· Using the pitless adapter wrench (T-handle tool), lower the final assembly until the adapter slides into and locks with the female part on the inside of the well casing. You should feel a distinct "clunk" as it seats.
1.Connect the Wiring: With the pump in place, you can complete the electrical connections at the wellhead. Route the submersible wire into the control box or pressure switch according to the manufacturer's diagram. Ensure all connections are tight and secure.
2.Install the Well Cap: Place the well cap back on top of the casing and tighten it down. Ensure the gasket creates a tight seal to prevent contaminants from entering the well.
1.Restore Power: Turn the circuit breaker back on.
2.Check for Operation: You should hear the pump turn on. It will run until the pressure tank is full and the pressure switch cuts the power.
3.Inspect for Leaks: Open a faucet in your home and check for steady water flow. Inspect the wellhead and any visible plumbing for leaks. The water may initially be cloudy with sediment, but it should clear up quickly.
Once your deep well water pump is installed and running, a few final steps will ensure its longevity. It's wise to test your water quality after any work on the well system to ensure it's safe for consumption. Consider a routine maintenance schedule where you check the pressure tank's air charge and listen for any unusual noises from the pump, which could indicate a future problem. A properly installed and maintained pump can provide reliable service for many years.
While installing a deep well water pump is a manageable DIY project for some, it has its challenges. If you are uncomfortable with electrical work, are dealing with a very deep well (over 150 feet), or encounter any unexpected issues, it is always best to call a licensed well professional. Their expertise ensures the job is done safely and correctly, protecting your investment and your water supply.
