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.

As soon as a water pipe is not under pressure or the noise from the leak cannot easily be heard the use of Tracer gas can be a very useful technique to locate water leaks in:

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

Tracer gas

The Tracer gas is introduced into the pipe with the leak from a cylinder of gas. 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 being both nontoxic and non-corrosive. The tracer gas contains hydrogen, which is the lightest and smallest molecule in the atmosphere, which will exit at the leak point and make its way to the surface where it is detected by the highly sensitive Variotec 460 gas detector.

Why use hydrogen as the tracer gas?

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

  • Non flammable
  • Non-toxic
  • Non-corrosive
  • 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.
