Losing access to water at home is more than just an inconvenience; it can bring your daily routine to a complete halt. If your water pressure has dropped or stopped entirely, a faulty deep well pump might be the culprit. While replacing a deep well pump can seem like a daunting task, it's a manageable project for a confident DIYer with the right tools and a bit of patience.
This guide will walk you through everything you need to know, from diagnosing the problem to safely installing a new pump. By following these steps, you can restore your home's water supply and gain the satisfaction of having tackled a major home repair project yourself. We'll cover the tools you'll need, the safety precautions to take, and a detailed process for a successful replacement.
Before you start pulling hundreds of feet of pipe out of the ground, it's important to confirm that the pump is actually the problem. Several signs can point to a failing deep well pump:
· No water: The most obvious sign is a complete lack of water from your faucets.
· Low water pressure: If your showers are weak and faucets only produce a trickle, the pump may be losing its ability to push water effectively.
· Dirty water: A failing pump can stir up sediment from the bottom of the well, resulting in cloudy or gritty water.
· Spiking electricity bills: A pump that has to work harder due to mechanical failure will use more energy, leading to an unexpected increase in your power costs.
· Constant pump cycling: If you hear your pump turning on and off frequently, even when you aren't using water, it could indicate a problem with the pump or the pressure tank.
If you're experiencing these issues, it's a good idea to first check the circuit breaker and the pressure switch. If those are working correctly, the deep well pump is the likely source of the problem.
Gathering all your tools and materials before you begin will make the process much smoother. You don't want to be halfway through the job and realize you're missing a crucial item.
· Pump puller or pulling rig: This is highly recommended, especially for very deep wells. It provides the mechanical advantage needed to safely lift the heavy pump and pipe.
· Pipe wrenches: You'll need at least two to grip and turn pipes.
· Socket wrench set and screwdrivers: For disconnecting electrical wiring and removing fittings.
· Wire cutters and strippers: Essential for handling the electrical connections.
· Heat gun and heat shrink tubing: For creating a waterproof seal on electrical splices.
· Safety rope: A strong rope to secure the pump and prevent it from falling back into the well.
· Multimeter: To test electrical connections and ensure power is off.
· Flashlight or headlamp: Wells are dark, and you'll need to see what you're doing.
· New deep well pump: Ensure it matches the horsepower, voltage, and flow rate of your old one.
· New pitless adapter (optional but recommended): This fitting creates a sanitary, frost-proof seal. Replacing it now can prevent future leaks.
· Teflon tape: For sealing threaded pipe connections.
· Electrical splice kit: Use a kit specifically designed for submersible pumps to ensure a waterproof connection.
· New check valve (optional): It's a good practice to replace the check valve when you replace the pump.
With your tools and materials ready, it's time to begin. Safety is the top priority, so work slowly and deliberately. It's also highly recommended to have a helper for this job.
Your safety is paramount. Go to your home's circuit breaker panel and shut off the power to the well pump. To be absolutely certain, use a multimeter to test the wires at the wellhead's pressure switch and confirm there is no electrical current.
The top of your well is protected by a well cap. Use a socket wrench or screwdriver to remove the bolts securing the cap. Once it's off, you'll see the top of the well casing, the electrical wiring, and the pitless adapter.
The pitless adapter connects the drop pipe coming from the pump to the water line running to your house. You'll need to use a T-handle puller tool that threads into the top of the adapter. Once it's threaded in, you can lift the adapter vertically to disengage it from its housing in the well casing. This allows you to pull the entire pump and pipe assembly straight up.
This is the most physically demanding part of the job. Secure your safety rope to the pipe just below the pitless adapter. If you're using a pump puller, set it up over the well casing according to the manufacturer's instructions.
Begin slowly pulling the pipe and pump assembly out of the well. As each section of pipe emerges, have your helper support its weight. You'll need to unscrew the pipe sections one by one using two pipe wrenches. Be careful not to drop any tools or the pipe itself back down into the well. As you pull, keep the electrical cable untangled and free from damage.
Once you've pulled the final section of pipe, the deep well pump will be exposed. Disconnect the electrical wires and the safety rope from the old pump. Carefully cut the wires near the pump, leaving enough length to make new connections.
Now, you'll reverse the process.
1.Prepare the new pump: Attach any necessary fittings, like a new check valve, to the outlet of the new pump using Teflon tape.
2.Splice the electrical wires: Using a waterproof splice kit, connect the wires from the well to the new pump. Match the colors correctly (black to black, green to green, etc.). Use a heat gun to shrink the tubing over the splices, creating a watertight seal. This step is critical; a bad splice will fail and require you to pull the pump all over again.
3.Attach the drop pipe: Securely attach the first section of drop pipe to the new pump.
4.Attach the safety rope: Tie the safety rope securely to the new pump. This is your insurance policy against dropping it.
Carefully begin lowering the new pump and pipe assembly back into the well, section by section. As you lower it, reattach each section of pipe, ensuring the threads are sealed with Teflon tape and tightened securely with pipe wrenches. Keep the electrical cable straight and alongside the pipe to prevent it from getting pinched or tangled.
Once you reach the final section, re-engage the pitless adapter into its housing. You should feel it lock firmly into place.
With the pump back in the well, you can reconnect everything at the wellhead.
1.Reinstall the well cap: Secure the cap back onto the well casing.
2.Turn the power back on: Go to the circuit breaker and restore power to the pump.
3.Test the system: The pump should turn on and start building pressure in the tank. Open an outdoor spigot to bleed air from the lines. It may take a few minutes for the water to run clear and smooth as air and any sediment are flushed out.
4.Check for leaks: Inspect all your connections for any signs of water leaks.
Replacing a deep well pump is a significant undertaking. You should consider calling a professional well service if:
· Your well is exceptionally deep (over 300 feet).
· You don't have the proper tools, especially a pump puller.
· You are not comfortable working with electrical wiring.
· You encounter any unexpected problems, like a stuck pipe.
While saving money on labor is a great benefit of DIY, the cost of fixing a mistake—like dropping the pump down the well—can far exceed the cost of hiring a pro from the start.
By taking a methodical and safety-conscious approach, you can successfully replace your deep well pump and restore water to your home. This project not only saves you money but also empowers you with the knowledge to manage your home's well system confidently. Remember to work carefully, double-check your connections, and don't hesitate to ask for help when you need it. A successful pump replacement means a reliable water supply for years to come.
