Common Leak Detection Methods to Find A Leak Used By Experienced Plumbers

What are some common leak detection methods to find a leak used by experienced plumbers? Glad you asked – here are 6 methods  …

Acoustics – Leak Detection

Using sensitive microphones to enhance the sound of the leak – are placed on the ground and pipes.
The Acoustic profiling method can help in pinpointing precise leak location. Acoustic Leak Detection saves your time, efforts as at time you may not identify the exact leak location manually.


Correlation – Leak Detection

The Correlator equipment method is a very accurate sound testing device which is used to identify when a pipe is leaking.

Correlation is a method of finding and pinpointing leaks in water pipes. A leak in a pipe under pressure can create a noise that travels through the pipe, the surrounding ground and in the contents of the pipe.

The correlator tool uses two identical sensors located along the pipe – it calculates and pinpoints the leak location by finding the delay in signal, sensor distance and sound velocity.


Tracer Gas – Leak Detection

The trace gas – a safe non-toxic mixture of hydrogen and nitrogen gas – is introduced into the pipe with the suspected leak.

The gas will exit at the leak point and make its way to the ground surface where it is then detected using gas sensitive detection probes.


Thermal Imaging – Leak Detection

Thermal Imaging is the use of an infrared imaging and measurement camera to “see” and “measure” thermal (heat) energy emitted from an object.

Thermography cameras can identify problem areas that can’t be seen readily with the naked eye, and makes detecting hidden water leaks easier even behind walls, ceilings and floors.

The infrared inspection camera can detect not only hidden water leaks but also their origin. Thermal Imaging can see moisture that cannot be physically reached with standard moisture meters.


Pipe Detection, Cable Detection, Tracing, Metal Detection – Leak Detection

Often the exact position of pipes, drains and cables is unknown. In order to carry out precise water leak detection and to avoid damage to other utilities during excavations, it is vital to know the precise position of all these extra services. National Plumbing use high performance equipment and methods which can locate and trace hidden and buried pipes and cables.


Water Noise Loggers – Leak Detection

Noise Loggers are used for early detection of leaks in the water supply piping. The installation of permanent noise loggers on water pipes is a cost effective tool in early identification of water loss. By permanently monitoring sections of the water system you can trouble shoot and alert you when a potential leak does develop.



National Plumbing’s Leak Detection Specialists use the most technologically advanced non-invasive methods to accurately locate hidden water leaks. From home leak detection to commercial leak detection – our team of dedicated specialists can assist you throughout Brisbane and the Gold Coast.
