Having your own private well is a major step toward self-sufficiency. It provides fresh, clean water for your home, independent of municipal systems. But what happens when you need to install or replace the heart of that system—the deep well pump? This task can seem daunting, but with the right tools, knowledge, and safety precautions, it's a project a capable DIYer can handle.
This guide will walk you through the entire process of how to install a deep well pump. We'll cover everything from the necessary preparations and safety checks to the step-by-step installation and final testing. By the end, you'll have the confidence to tackle this project and get your water flowing freely.
Before you start, it's important to understand the components you'll be working with. A deep well submersible pump system is designed for wells where the water level is more than 25 feet below the surface.
Key components include:
· Submersible Pump: This is the workhorse of the system. It's a cylindrical pump that sits deep inside the well casing, submerged in water.
· Drop Pipe: A rigid pipe that connects the pump to the surface, carrying water upwards.
· Well Casing: The outer pipe that lines the drilled well hole, preventing it from collapsing and keeping contaminants out.
· Pitless Adapter: A fitting on the well casing below the frost line that allows the water line to run horizontally to your house without freezing.
· Well Cap: A secure cover on top of the well casing that prevents debris and contaminants from entering the well.
· Electrical Wiring: A waterproof electrical cable that runs from the pump to the control box.
· Safety Rope: A rope tied to the pump that acts as a backup for retrieval.
· Pressure Tank & Control Box: Located inside your home (usually in a basement or utility room), these components regulate water pressure and control the pump's operation.
Understanding how these parts work together is the first step toward a successful installation.
Proper preparation is non-negotiable for a project of this scale. Rushing in without the right gear can lead to costly mistakes or serious injury.
Gather everything you'll need before you begin. Here's a comprehensive checklist:
· New Deep Well Pump: Ensure it's the correct horsepower (HP) and voltage for your well's depth and your home's needs.
· Drop Pipe: PVC or polyethylene pipe of the appropriate length and diameter.
· Pipe Fittings: Including male adapters for the pump and pitless adapter.
· Submersible Pump Wire: Correct gauge and length for your pump's depth and power.
· Waterproof Splice Kit: For making a secure, watertight electrical connection.
· Safety Rope: Strong nylon or polypropylene rope.
· Teflon Tape and Pipe Dope: For sealing threaded pipe connections.
· Well Cap: A new, sanitary well cap is recommended.
· Pipe Wrenches: At least two for tightening fittings.
· Wire Strippers and Crimpers: For electrical work.
· Heat Gun: To shrink the waterproof splice kit tubing.
· Utility Knife, Screwdrivers, and Wrenches.
· A strong helper: This is not a one-person job. The pump and pipe assembly can be very heavy and awkward.
Working with a deep well involves significant risks. Always prioritize safety:
· Turn Off the Power: Before you do anything, go to your home's circuit breaker and shut off the power to the well pump. Lock the breaker box or place a prominent sign to prevent anyone from accidentally turning it back on.
· Wear Protective Gear: Safety glasses and gloves are essential.
· Never Work Alone: Always have at least one other person with you. Dropping a pump down a well is an expensive and difficult problem to fix.
· Secure the Well Opening: Once the cap is off, be extremely careful not to drop tools, parts, or anything else down the well.
With your tools gathered and safety checks complete, you're ready to begin the installation.
Unbox your new deep well pump. Attach a male threaded adapter to the outlet port on top of the pump. Wrap the threads with Teflon tape (3-4 wraps in a clockwise direction) and apply a thin layer of pipe dope for a leak-proof seal. Tighten it securely with a pipe wrench.
Next, attach your safety rope. Thread it through the designated eyelet on the pump and tie a secure knot, like a bowline. This rope is your lifeline if you ever need to pull the pump for maintenance.
This is the most critical step. A faulty connection will fail, and you'll have to pull the entire assembly back up.
1.Strip the Wires: Carefully strip about half an inch of insulation from the ends of the pump's motor wires and the submersible electrical cable.
2.Splice the Wires: Use a high-quality waterproof splice kit. Connect the corresponding wires (usually color-coded) using the provided connectors. Crimp them tightly for a solid mechanical connection.
3.Insulate and Waterproof: Follow the splice kit's instructions precisely. This usually involves sliding a heat-shrink tube over each connection and using a heat gun to shrink it until it forms a tight, waterproof seal. Then, a larger tube often covers all the connections together. Take your time here—a perfect seal is essential.
4.Secure the Cable: Once the splice is complete, neatly tape the electrical cable and the safety rope to the drop pipe every 5-10 feet using electrical tape. This keeps everything organized and prevents the wires from snagging on the way down.
Now, you'll start assembling the column that goes into the well. Attach the first section of drop pipe to the adapter on the pump. If using threaded PVC, apply Teflon tape and pipe dope to the male threads before tightening.
This is where your helper is crucial.
1.Position the Pump: Carefully position the pump over the well casing opening.
2.Lower Slowly: One person will guide the pump and pipe into the well, while the other manages the electrical cable and safety rope, ensuring they don't get tangled or snagged.
3.Add Pipe Sections: As you lower the assembly, continue adding sections of drop pipe. For each connection, use Teflon tape and dope and tighten securely. Remember to tape the wire and rope to the pipe as you go.
4.Attach the Pitless Adapter: The last piece to attach to your drop pipe is the male half of the pitless adapter.
Lower the entire assembly until the pitless adapter is aligned with the female fitting inside the well casing. You'll need a special T-handle tool that screws into the top of the pitless adapter to guide it into place.
Once aligned, push it firmly until it slides into the receiving slot and creates a watertight seal. You may hear or feel a click as it seats correctly. This connection allows water to flow from the vertical drop pipe to the horizontal line running to your house.
With the pump in place, you can make the final connections.
1.Connect the Electrical Wires: Route the submersible cable through the well cap. Connect the wires to the wiring block inside the cap, following the manufacturer's diagram. Connect the ground wire to the designated grounding screw.
2.Secure the Well Cap: Place the sanitary well cap securely on top of the well casing and tighten the bolts. This prevents contamination from entering your well.
3.Tie off the Safety Rope: Tie the loose end of the safety rope to the eyelet provided inside the well cap. Leave a little slack, but ensure it's secure.
Head inside to your pressure tank. Before turning the power on, you need to prime the system. Slowly open the valve on the water line coming from the well to allow water to fill the pressure tank and plumbing. Listen for any sounds of leaks at the tank and check the connections.
Once the system is full, it's time for the moment of truth.
Go back to your circuit breaker and turn the power to the pump back on. The pump should kick on, and you should see the pressure gauge on your tank begin to rise. Let it run until it reaches the cut-off pressure (usually 50-60 PSI) and shuts off automatically.
Open a faucet in your home. The water may sputter at first as air is purged from the lines. Let it run until the stream is steady. The pressure will drop, and the pump should kick back on at the pre-set cut-in pressure (usually 30-40 PSI). Watch a full cycle to ensure the system is operating correctly.
Installing a deep well pump is a significant undertaking, but it's a rewarding one. By taking a methodical approach, prioritizing safety, and ensuring every connection is secure, you can successfully restore your home's private water supply. This project not only saves you the cost of a professional plumber but also gives you a deeper understanding of the system that provides your family with fresh water every day.
If at any point you feel unsure or encounter a problem you can't solve, don't hesitate to call a professional well service. It's better to ask for help than to make a mistake that could damage your well or your new pump.
