Mystery Leak Detection in Memphis, TN

When the Source Is Unknown

Not every leak announces itself with a puddle on the floor. Some of the most damaging leaks in Memphis-area homes are the ones you cannot see — hidden behind walls, beneath concrete slabs, or deep underground between the water meter and your house. By the time you notice the symptoms, weeks or months of damage may have already occurred.

Mystery leak detection is an investigative process. We do not just listen for one sound or check one pipe — we systematically eliminate possibilities until we isolate the source. Using a combination of acoustic sensors, thermal imaging cameras, pressure testing, and decades of experience, we trace the water back to its origin point.

Our Investigation Process

We follow a systematic elimination process to trace the water back to its source — no guessing, no unnecessary demolition.

Step 1: Water Meter Analysis

We start at the MLGW meter to confirm whether water is flowing when it should not be. This determines if the leak is on your side of the meter or the utility’s.

Step 2: System Isolation

We systematically shut off zones of your plumbing to narrow down which system — supply, drain, or irrigation — contains the leak.

Step 3: Acoustic Detection

Using electronic listening equipment and ground microphones, we listen for the sound of pressurized water escaping through pipe walls or joints — even through concrete, soil, and drywall.

Step 4: Thermal Imaging

Infrared cameras reveal temperature differences behind walls and beneath floors, showing where water is traveling — not just where it surfaces.

Step 5: Pinpoint & Report

We mark the exact location of the leak and provide a detailed report documenting our findings, suitable for insurance claims or contractor repair quotes.

Common Mystery Leak Symptoms

If you are experiencing any of these symptoms, you may have a hidden leak that requires professional investigation:

Unexplained water bill increases — Your MLGW bill is higher than normal but nothing visible is leaking. This often indicates a slab leak or underground pipe failure.

Water stains with no obvious source — Ceiling stains, damp drywall, or peeling paint that appears without any visible plumbing above. The leak may be traveling along joists or pipes from a distant source.

Warm spots on the floor — A hot-water slab leak creates a warm area on your tile or hardwood that should not be there. Often noticed while walking barefoot.

Sound of running water — You hear water running when every faucet is off. This is one of the clearest indicators of a hidden pressurized leak.

Musty or moldy smell — Persistent damp odor in a room or area, especially in closets, bathrooms, or near exterior walls. Hidden moisture feeds mold growth behind surfaces.

Foundation cracks or shifting — Water saturating the soil beneath your foundation can cause it to shift, creating visible cracks in walls or floors.

Wet yard with no rain — Soggy patches in your lawn, especially near the water meter or along the path of buried pipes, suggest an underground line leak.
