In this short video, we are right above the location of a water leak in our client's lawn area. The meter is on the other side of the sidewalk. This is not a leak in the irrigation pipes, it is in the supply line feeding the irrigation system. The leak was costing over $400 a month in wasted water and the location of the leak was not obvious.

We had already narrowed down the area we thought the leak would be using our acoustic system. We were on a reasonably busy city street, so we were not sure exactly the location of the leak as we picked up noise from passing cars.

By shutting off the water at the meter and the irrigation system’s shutoff valves, we were able to isolate that section of the pipe and, using our tracer gas system, fill the section of pipe with our tracer gas mixture. The gas will escape at the point of the water leak and rise to the surface where our equipment can detect it. This is a very useful method for pinpointing the location of a leak that not everyone has. We can detect leaks through a cement driveway using tracer gas.

The tracer gas mixture is 5% Hydrogen and 95% Nitrogen which is non-toxic and non-flammable.
