Why Submersible pump installation Matters for Your Water Supply
A proper submersible pump installation involves setting up a water pump that operates fully submerged in your well to deliver reliable water pressure. Here’s a brief overview of the process:
Key Steps for Submersible Pump Installation:
- Size your pump correctly based on well depth and household water needs.
- Gather essential components like the pump, drop pipe, pressure tank, and pitless adapter.
- Prepare the well by ensuring the casing is clean.
- Assemble the pump by connecting the drop pipe, wires, and safety rope.
- Lower the pump into the well and secure the pitless adapter.
- Complete electrical connections to the control box and pressure switch.
- Test and sanitize the system by checking for leaks and flushing with a chlorine solution.
Submersible pumps are often preferred over surface pumps because they are more efficient, quieter, and longer-lasting. They push water upward rather than pulling it, and the surrounding water keeps the motor cool.
When our family built this business in the 1940s, we learned that proper submersible pump installation isn’t just about connecting pipes—it’s about ensuring generations have access to clean, reliable water. I’m Chelsey Christensen, and after years of working on well systems across Ohio, I’ve seen how a correctly installed pump makes all the difference. Whether you’re a homeowner tackling a DIY project or deciding when to call in professionals, this guide will walk you through every critical step.
The Complete Guide to Submersible Pump Installation
This section covers everything from choosing the right components to flipping the switch on your new system, ensuring you have the knowledge for a successful installation.
Preparation: Sizing, Tools, and Safety
Before we even think about touching a wrench, meticulous preparation is key to a flawless submersible pump installation. This involves correctly sizing your pump, gathering the right tools, and, most importantly, prioritizing safety.
Pump Sizing: The Foundation of Your Water System
Choosing the correct pump size is crucial. A pump that’s too small will lack power, while one that’s too large wastes energy. Key factors include:
- Water Needs: Estimate your household’s daily water usage to determine the required flow rate (Gallons Per Minute or GPM).
- Well Characteristics: Submersible pumps are ideal for wells deeper than 25 feet. The well’s total depth, static water level, and drawdown are used to calculate the total dynamic head (TDH), which determines the necessary horsepower. The deeper the well, the more robust the drop pipe and wire must be.
Essential Tools and Materials
Gather your equipment beforehand to save time. You’ll need specialized components in addition to standard plumbing and electrical tools:
- Core Components: Correctly sized pump, drop pipe, captive-air pressure tank, pressure switch, and check valve.
- Well Connection: Pitless adapter (for cold climates like Ohio) or a well seal.
- Installation Hardware: Submersible electrical wire (sized for depth), polypropylene safety rope, torque arrestor, and waterproof heat shrink splice kits.
- Plumbing/Electrical Tools: Pipe cutters, wrenches, Teflon tape, wire strippers, and a multimeter.
- Safety Gear: Always use protective gloves and safety goggles.
Safety Precautions: Our Top Priority
With over 70 years of experience, we know that safety is non-negotiable.
- Electrical Safety: Always turn off power at the circuit breaker before starting. Use a GFCI-protected power source and never handle a powered pump near water. All electrical work must comply with local and National Electrical Codes (NEC).
- Personal Protective Equipment (PPE): Wear safety goggles and protective gloves.
- Well Preparation: Ensure the well casing is clean and free of debris.
- Heavy Lifting: Pump assemblies are heavy. Use caution when lowering or pulling the pump, and always rely on the safety rope, not the electrical cable, to support the weight.
Understanding Your System: Key Components and Their Roles
A successful submersible pump installation relies on understanding each component’s function. Think of it like an orchestra – every instrument plays a vital role in the final performance.
- Submersible Pump: The heart of the system, this pump is installed deep in the well to efficiently push water to the surface.
- Check Valve: Prevents water from flowing back into the well when the pump shuts off, which maintains pressure and protects the pump from short-cycling.
- Pressure Tank: A captive-air tank stores water under pressure, creating a reserve that reduces how often the pump needs to run, extending its lifespan.
- Pressure Switch: This switch monitors system pressure, automatically turning the pump on at a low-pressure setpoint and off at a high-pressure setpoint.
- Pitless Adapter: Essential in climates like Ohio’s, this device allows the water line to exit the well casing below the frost line, preventing freezing and creating a sanitary seal.
- Torque Arrestor: Installed above the pump, it prevents the motor’s startup torque from twisting the pipe and damaging the electrical cable against the well casing.
- Safety Rope: Attached to the pump, this rope provides a secure way to lower and retrieve the unit, preventing it from being lost if a pipe connection fails.
- Submersible Wire: A specialized, waterproof wire that delivers power to the pump motor. It must be correctly sized for the well depth to avoid voltage drop.
- Well Seal: A cap that covers the top of the well casing to keep out debris and contaminants.

- Assemble the Pump and Drop Pipe:
Attach a check valve to the pump’s discharge outlet, then connect the drop pipe. Splice the pump’s wire to the main submersible wire using waterproof heat shrink kits, staggering the connections. Install a torque arrestor above the pump and securely attach the safety rope. Finally, tape the wire and safety rope to the drop pipe every 10-20 feet. - Prepare the Well and Lower the Assembly:
After ensuring the well casing is clean, carefully lower the entire assembly into the well. The pump should be suspended well off the bottom to avoid pulling in sediment. - Secure the Pitless Adapter and Connect Piping:
At the correct depth, lock the pitless adapter into place to create a watertight seal below the frost line. Connect the discharge pipe from the adapter to the pressure tank, ensuring all connections are tight. Install a union for easy servicing and a code-required pressure relief valve. - Complete Electrical Connections:
With the power off, wire the pump cable to the control box, then connect the control box to the pressure switch and the switch to the circuit breaker. Proper grounding is critical for safety.

Post-Installation: Testing, Sanitizing, and Maintenance
Once your submersible pump installation is complete, a few final steps ensure everything is working perfectly and your water is safe to drink.
System Testing: The Moment of Truth
After all connections are made and checked, it’s time to power up and test:
- Initial Startup: Turn on the power and let the pump run until the water is clear of any sand or debris.
- Check for Leaks: Inspect all plumbing connections for drips and tighten as needed.
- Monitor Pressure: Watch the pressure gauge to confirm the pressure switch is cycling the pump correctly. The pressure tank’s air charge should be set 2 psi below the cut-on pressure.
Well Sanitization: Ensuring Potable Water
Sanitizing your well system after any work is a critical step to ensure your water is safe from bacterial contamination.
- Introduce Chlorine: Pour a calculated amount of household bleach (e.g., 3 pints per 100 gallons of water) into the well.
- Circulate and Sit: Run an outside hose back into the well to circulate the chlorine. Then, run each faucet until you smell chlorine and let the solution sit in the system for at least 12 hours.
- Flush System: Thoroughly flush the system using an outside hose until the chlorine smell is gone. Avoid flushing chlorinated water into your septic system.
Routine Maintenance: Longevity is Key
Regular maintenance ensures the longevity and optimal performance of your submersible pump. According to the U.S. Environmental Protection Agency (EPA), private well owners should inspect and maintain their systems regularly.
- Monthly Checks: Briefly check water quality and pressure.
- Quarterly Checks: Inspect electrical connections and the pressure tank’s air charge.
- Annual Inspections: We recommend scheduling annual comprehensive system checks to assess pump performance, inspect the well cap, and look for potential issues. For more on this, read How Often Should a Well Pump Be Serviced?.
