Is there a tool to find a water leak underground?

Yes, several tools and technologies can detect underground water leaks without digging. The most common include acoustic water leak detectors (ground microphones) that listen for hissing sounds, ground-penetrating radar (GPR) for locating subsurface anomalies, and thermal imaging cameras for identifying cold spots caused by water evaporation.

How deep are most residential water lines?

Typically, water lines are buried at a depth ranging from 18 inches to 5 feet, depending on various factors such as local climate, soil conditions, and the type of water system in place.
