How to Find a Water Leak

Our highly trained engineers at L.D.S. Leak Detection Specialists Ltd. will choose the approriate testing and inspection process specifically chosen to suit your home or commercial business to find the leak.

Our engineers at L.D.S. carry all the latest technology in leakage detection. We have listed the main Leak detection methods and equipment below. Inspection cameras. Protimeter mms damp meter survey kits, pressure gauges both hydraulic and digital and salts diagnostic kits also form part of the L.D.S. engineers equipment.

Leak Detection Methods to Find A Leak

Acoustics
Acoustic profiling uses ground and pipe sensitive microphones to enhance the sound of the leak. This method can help in pinpointing precise leak location.

Correlation
Is a way of finding and pinpointing leaks in water pipes. A leak in a pipe under pressure creates noise that travels through the pipe walls, the surrounding ground and along the contents of the pipe. Correlators are a very accurate sound testing device which are used to identify the acoustic frequency caused when a pipe is leaking. The correlator uses two identical sensors located along the pipe to calculate the leek location by logging the signal delay, sensor distance and the sound velocity.

Tracer Gas
The trace gas, a safe mixture of hydrogen and nitrogen, is introduced into the pipe with the suspected leak. The gas, is the lightest in the atmosphere and is made up of of small molecules. The gas will exit at the leak and make its way to the surface where it is detected using gas sensitive detection pobes.

Thermal Imaging
Thermography is the use of an infrared imaging and measurement camera to see and measure thermal energy emitted from an object. Thermography cameras can identify problem areas that can’t be seen with the naked eye, detecting hidden water leaks. The infrared inspection camera can detect not only hidden water leaks and their origin, but also moisture that cannot be physically reached with moisture meters. Read more

Pipe, Cable and Metal Detection and Tracing
Often the exact position of pipes and cables is unknown due to innacurate or non existant network plans. In order to carry out precise water leak detection and to avoid damage to utilities and operators during excavations, it is essential to know the precise position of all services. We use high performance equipment which can locate and trace buried pipes and cables.

Network Monitoring with Noise Loggers
Noise Loggers are used for early detection of leaks in water supply networks.The longer it takes to identify that a network is leaking the more revenue is lost and the greater the loss of precious water resources. In addition to the more conventional methods of leak detection the installation of permanent noise loggers has proved to be a cost effective tool in early identification of water loss. By permanently monitoring sections of the system, which have previously been proven leak free, it will alert you when a potential leak does develop. Read more .
