How to Find a Leak in a Water Pipe

locate water leak

Our clients often call us asking if we can locate a water leak with our utility locating equipment. While this technology doesn’t give us the exact location of the leak, there are different ways to detect it.

According to the Alliance for Water Efficiency, the typical home loses 2,000 to 20,000 gallons of water per year due to leaks.  Some leaks go undetected for years because the source of the leak is not visible. Such is the case of a leak in a supply pipe that is buried at least 3 feet underground.

When our analyst arrives on your site, he/she will use the utility locating equipment (pictured above) to scan for the water line. On the screen, objects like this line will show up as a hyperbola. From that initial reading, the analyst can follow the path of the line and mark it as he/she goes.

For some clients, this is very useful for inspection. They know exactly where their water line is, so they can excavate and make sure that everything is in good condition. For most clients, they want to know if there is a leak. And if so, where is it exactly?

Our analyst would look for signs of wet or damp soil, this indicates a possible leak and the location of it. When we scan over the leak, the wet soil will typically show up on the screen as a bright reflection. This is an indicator that the equipment has detected a possible water leak.
