If your water pressure has dropped dramatically or your faucets have stopped running altogether, it might be time to replace your submersible well pump. These pumps are vital to moving water from your well to your home, but like any piece of equipment, they don’t last forever. While replacing a submersible well pump may seem like an intimidating task, with the right tools, safety measures, and a bit of patience, it’s a job you can tackle yourself.
This guide will walk you through everything you need to know about replacing a submersible well pump, including preparation, step-by-step instructions, and tips for a successful installation.
A submersible well pump is a device installed deep below ground in a well, designed to push water to the surface. Unlike other types of pumps, such as jet pumps, a submersible pump is actually submerged in water, which helps cool its motor. Most residential pumps are located 100 to 400 feet deep and can last 8 to 15 years before needing replacement.
Signs that your submersible well pump might need replacement include:
● No water coming from faucets.
● Water pressure that fluctuates or is consistently low.
● Dirty or cloudy water being pumped to your home.
● Higher-than-usual electric bills, indicating the pump is working harder than it should.
Before jumping into the replacement process, make sure to confirm that the pump is indeed the issue. Other components, such as a faulty pressure switch or clogged pipes, could also be the culprit.
Replacing a submersible well pump requires specific tools and materials. Make sure you gather the following before starting:
● New submersible well pump (ensure it's compatible with your existing system).
● Pump control box (if required for your model).
● Safety harness and gloves for personal protection.
● Hex wrench for well cap removal.
● Pipe wrench or pliers to secure piping.
● Teflon tape for sealing pipe connections.
● Electrical tape for wiring connections.
● Ohmmeter for testing electrical connections.
● Submersible pump wire if replacement is necessary.
● Pipe clamps for holding the drop pipe steady.
● Winch or tripod for safely lifting heavy pumps.
Having everything ready and easily accessible will make the process much smoother and safer.
Safety always comes first. Start by switching off the circuit breaker connected to your well pump to avoid any danger of electrical shock. Also, shut off the valve controlling water flow from the well to your home.
Use a voltage tester to confirm that no electricity is flowing to the pump before proceeding.
The well cap is the protective cover on the top of your wellhead. Use a hex wrench to loosen and remove the bolts. Carefully lift the cap, being mindful of any wires connected to it.
If your well has a sanitary seal, be sure to take note of how it is configured for replacement later.
You’ll find electrical wires connected to the pump just below the well cap. Make sure to label each wire or take a photo before disconnecting them—that way, reattaching them later will be much easier.
Inspect the wires for damage, as you may need to replace old, worn wiring during the installation.
The pump is attached to a length of drop pipe, which may be several hundred feet long. This is where a winch or tripod system becomes essential to lift the pump and piping safely and steadily out of the well.
If you do not have access to a winch, you can enlist the help of a few people to manually pull the pipe. Be careful to avoid damaging the pipe or pump as you work.
Once the pump is out of the well, locate the connection point where the pump meets the piping. Use a pipe wrench or pliers to carefully detach the pump from the pipe. Remove any remaining wiring as well.
Inspect the pipe, fittings, and wiring for wear or damage, as you may need to replace them before installing the new system.
Follow these steps to install the new pump:
1.Attach the piping: Securely connect the drop pipe to the new pump, using Teflon tape to seal the threads and prevent leaks.
2.Connect the wiring: Attach the electrical wiring to the pump, ensuring all connections match the configuration of the old pump. Use waterproof electrical tape to cover exposed wiring for added protection.
3.Secure the pump: Use pipe clamps to ensure the pump and piping are strongly connected and will not come loose during operation.
Check that all components are secure before lowering the pump back into the well.
Lower the pump and piping carefully into the well, allowing someone to feed the pipe down steadily. Take it slow to avoid damaging the pump, pipe, or wiring.
Once the pump is fully submerged, reattach the wiring to the wellhead and secure the well cap in place.
Switch the power back on at the circuit breaker. Test the system by turning on a faucet in your home. If the water flows smoothly and the pressure is consistent, congratulations! You’ve successfully replaced your submersible well pump.
If the pump does not operate properly, double-check the wiring connections and ensure the pump is correctly seated in the well.
● Avoid Working Alone: Always have someone assist you, especially when lifting the pump and piping.
● Keep the Area Clean: Dirt or debris that falls into the well could affect water quality and pump operation.
● Inspect Everything: Take the time to check and replace any worn or damaged parts during the installation process.
● Research the Right Pump: Ensure the new pump is the correct size and capacity for your well and home system.
While replacing a submersible well pump can be done as a DIY project, there are situations where hiring a professional is the safer and smarter choice. Consider calling a licensed well technician if:
● The pump is located more than 200 feet deep.
● You lack the necessary tools or experience with electrical wiring.
● Your well system includes complex components like additional tanks or booster pumps.
Replacing a submersible well pump might be a challenging task, but with careful preparation and attention to detail, it’s completely manageable. Whether you’re dealing with low water pressure or no water at all, a new pump can restore your home’s water supply and provide years of reliability.
Take your time, stay safe, and enjoy the rewarding feeling of a job well done. If you're not confident in managing the project, remember that professional help is always a call away.
