Water Line Leak Detection & Repair in Memphis, TN

What Is a Water Line Leak?

Your water line — also called the service line — is the pipe that carries pressurized water from the MLGW meter at the street to your home. In Memphis, these lines are typically 3/4-inch to 1-inch copper, galvanized steel, or polyethylene pipe buried 18 to 36 inches underground. Because the line is under constant pressure, even a small crack or corroded spot can waste enormous volumes of water.

Memphis water lines are subject to particular stresses: our expansive clay soil shifts with moisture content, the Memphis Sand Aquifer’s water chemistry accelerates copper corrosion, and the proximity of the New Madrid Seismic Zone means periodic microseismic activity adds cumulative strain to buried infrastructure. Homes in East Memphis, Midtown, Whitehaven, and Frayser with water lines installed before 1990 are at highest risk.

Our Water Line Leak Detection Process

We use a systematic approach to locate water line leaks precisely, saving you from unnecessary excavation and getting you to a repair faster.

Step 1: Meter Verification

We start at the MLGW meter. With all fixtures off inside the home, we observe the meter’s flow indicator. If water is moving, we know the leak is on the service line. We calculate the approximate leak rate in gallons per hour.

Step 2: Pressure Isolation Testing

We isolate the water line at the house entrance and apply a static pressure test to the buried section only. By monitoring the pressure drop over time, we confirm the leak is on the main service line and estimate its severity.

Step 3: Acoustic Pinpointing

Using ground-level acoustic sensors and a correlating receiver, we listen for the sound of pressurized water escaping through the pipe wall or joint underground. The equipment calculates the distance to the leak based on the speed of sound through the pipe material.

Step 4: Precise Marking & Repair Coordination

We mark the exact leak location on the ground surface with spray paint and provide measurements from fixed reference points. Our report includes the estimated leak rate, pipe material assessment, and repair recommendations.

Signs of a Water Line Leak

Water line leaks waste water 24 hours a day because the supply line is always under pressure. Watch for these warning signs:

Unexplained increase in your MLGW water bill — A water line leak can waste 1,000 to 10,000 gallons per day, adding $50 to $500 or more to your monthly bill. MLGW does offer a one-time adjustment for documented leak repairs.

Water meter spinning when nothing is running — Turn off every fixture and appliance, then check the meter. If the flow indicator is still moving, water is leaving the system somewhere between the meter and the house.

Low water pressure at all fixtures — A water line leak diverts water before it enters your home. If pressure is low at every faucet and shower simultaneously, the problem is likely upstream of the house.

Wet areas or standing water in the yard — Persistent moisture, puddles, or muddy spots between the street and the house strongly suggest a water line failure.

Sound of water running near the meter — Pressurized water escaping through a crack or joint produces a hissing or rushing sound that can sometimes be heard near the meter or house entry point.

Discolored water when you first turn on a tap — Rust-colored or sediment-laden water can indicate a corroded water line allowing soil to enter through the leak point.

Frequently Asked Questions

How much water can a water line leak waste?

A water line leak can waste anywhere from 500 to 10,000 gallons per day depending on the size of the break and the water pressure. At Memphis MLGW water rates, even a moderate leak can add $100 to $300 per month to your bill.

Will MLGW adjust my bill for a water line leak?

MLGW offers a one-time bill adjustment for documented underground water leaks. You need to provide proof that the leak was repaired. Our detection report combined with your plumber’s repair receipt provides the documentation needed.

Is the water line my responsibility or MLGW’s?

MLGW is responsible for the water main in the street, the service tap, and the meter itself. Everything from the meter to the house is the homeowner’s responsibility. This is the section Patton Leak Detection inspects.
