A mixture of hydrogen and nitrogen gas is used to replace water in the suspect plumbing system. Under pressure, this gas will escape from any leak. The gas can travel through walls, concrete floors, and timber. A sensitive tracer pinpoints the leak by picking up any trace of the gas down to just a few parts per million.
The image on the right shows just one the types of gas tracing kits we use in our day to day leak detection services.
