When a pressurised water pipe develops a leak, the water flows out of it into the surrounding ground at high speed, which causes the pipe and soil to vibrate at the exit point. This sound, or vibration, is transmitted by the pipe and surrounding material where it can be heard with the highly sensitive microphones.


Qld Utility Locating have invested in the best equipment for leak detection. We use Sewerin AQUAPHON acoustic equipment that is designed for professional, electroacoustic water leak detection.

The Sewerin Aquaphon A50 receiver, together with an array of microphones enables us to customize each location and leak detection situation for an successful outcome.


There are many simple checks you can conduct on your own property. Sometimes the source of a leak is really obvious and can be located by completing these simple inspections yourself –


  • Check all the house hold taps to make sure they are not dripping or running.
  • Hidden taps – ensure you check dishwasher tap and laundry taps connected to a washing machine. These taps are usually out of sight and often forgotten.
  • Check toilet cistern for running water into the toilet bowl after cistern is completely full.


After checking to see that no water is dripping or running inside your property, carry out these simple checks -

  • Check if water is pooling on the grass lawn or water marks on internal or external wall.
  • Check the electric or gas hot water system valves are not dripping or running
  • Check roof installed solar hot water unit. These are harder to inspect as they are typically installed on the house roof and are harder to review. Typically, a leak be coming from the relief valve which can be overflowing into the gutter of the house.
  • Check all external water taps used for gardens, garages, outdoor living areas.


Monitoring the readings on your external water meter can show where water usage may be abnormally high. To review your water usage, take an overnight reading from the water meter. Review it again the next morning and calculate the amount of water used.


Be aware of the location of your water meter. In the event of a major water leak, you can quickly turn off the water supply to your premises.

If you reside in a block of units or a commercial property water meters can be harder to locate and then once located, you may be presented with issues shutting off the supply. Qld Utility Locating so we can assist you with water meter location and shut down of supply to your premises.
