Leak Detection

Leak Detection

Do you have a high water bill and cannot understand how it is possible? Let us assist you in finding the problem.

When a water pipe is not under pressure or the noise from the leak cannot easily be heard, the use of tracer gas is a very useful technique to locate water leaks in:

  • Customer Supply Pipes
  • Underwater Heating Systems
  • Boilers
  • Central Heating Systems
  • Mains Distribution Networks

Tracer gas

Tracer gas is introduced, from a cylinder of gas, into the leaking pipe. The gas contains hydrogen, which will exit at the leak point and make its way to the surface where it is detected by a highly sensitive [Variotec 460] gas detector.

The tracer gas used to find water leaks is a mixture of hydrogen (5%) and nitrogen (95%) making it completely safe to use in drinking water supplies as it is both non-toxic and non-corrosive.

Why use hydrogen as tracer gas?

Hydrogen, at a level of 5% in a balance of nitrogen, is:

  • Non-flammable, non-toxic, non-corrosive and 100% safe.
  • Commonly used as a blanket gas in welding so is affordable and readily available from all the standard gas suppliers.
  • Has the smallest and lightest molecules so fills all surfaces including concrete, tarmac, block paving and grass, rising quickly to the surface.
  • Rapidly dissolves in air allowing you to hone in quickly to the source.
  • Unlike helium leak detection, which has also been used for some types of leak detection tracing, hydrogen is renewable and cheap; helium is finite and expensive.
