12 things you may not know about water leak detection

  1. External leaks may not cause disruption, but can dramatically increase your water bills.

  3. Internal leaks, if not identified and repaired, can cause major damage and destruction to a property, and seriously compromise its structural integrity

  5. Traditional methods of leak detection can involve major, unnecessary excavations and upheaval, with no guarantee that the leak will be found

  7. Today, leaks from buried pipes can be identified with thermal imaging cameras. They will show up any differences in surface temperature will show providing evidence of where the leak is originating from.

  9. Thermal imaging may be unsuccessful if pipes are very well insulated or buried deep in structural materials, making it impossible to identify a change in temperature at the surface.

  11. Leaks which are buried really deep may require acoustic listening devices to track them. Specialist acoustic listening device which are in effect sophisticated ground microphones, can be used to trace and pinpoint the location of the leak by detecting the vibration of the water leak from its exit point

  13. Where no acoustic signal is detected, a tracer gas system can be utilised. This works by draining the water from the suspected system and introducing a tracer gas under pressure, to the system.

  15. Tracer gas is made up of 95% nitrogen and 5% hydrogen. Hydrogen being the smallest and lightest molecule will escape from the pipe at the point of the leak and make its way to the surface where it can be detected by a sensitive gas detector.

  17. The advantages of this particular mixture the tracer gas used in water leak detection are that it is non flammable, non toxic, non corrosive and does not damage the environment in any way.

  19. To look inside cavities within building structures another device used by leading water leak detection experts is an endoscope.

  21. Unlike most other imaging devices, endoscopes are inserted directly into the cavity by drilling a small hole.

  23. Endoscopy can also involve the use of ‘borescopes’ where direct line of-sight observation is not feasible.
