Acoustic Water Leak Detection isolates the sound of water escaping the pipework to locate the leak
Water leaks occur every day, but they’re often more difficult to pinpoint than you might expect. That’s because a multitude of utility pipes can be concealed underground, behind walls and in ceilings. Whether there’s a leak in your home, office or commercial property, using acoustic water leak detection means we can pinpoint the location of issue without any intrusive excavation.
There are several warning signs for plumbing leaks, ranging from sudden puddles in your backyard to a drop in your water pressure, or a build-up of water in your walls or ceilings, all with potentially disastrous consequences. One thing is for certain, it needs to be fixed fast, but how?
The process of detection can be lengthy, costly, and can even lead to plumbers tearing up your walls in search of the issue – but what if you could avoid all that? This is where the acoustic method comes in to assist with water leak detection.
Some common signs of water leaks:
- Unusually wet areas on lawn or paving
- Noticeable drop in water pressure
- Unexplained increases in water usage/increased water bills
- Buckled ceilings
Do you have these tell-tale signs of a water leak?
How do acoustic water leak detectors work?
Water leaks make sounds which are transmitted on the pipes and also to the surface. Not every leak will sound the same because factors such as water pressure, soil type and depth, surface cover and pipe construction all affect the frequency and loudness of the sound.
Pipe and Cable Location Technology
Pipe and cable locator equipment is used to mark the location of water lines using electromagnetic transmission. This means a transmitter is carefully calibrated to induce a frequency into the ground. A receiver is then used to detect the pipe or cable which re-radiates the signal. Toscano Plumbing’s highly-trained plumbers interpret the signal so the pipe location can be mapped out. This makes it easier to identify the location of the leak with an acoustic leak detector.
Acoustic Leak Detection Technology
The pre-location of water pipes can also be done using an acoustic leak detector. By connecting a stopper to the line believed to be leaking, this opens and closes a valve to create a rhythmic pulsation. The pulsing can then be detected through the ground with an acoustic listening stick. The pulsing sound is loudest when the microphone is positioned directly over the pipe. That point is marked, and this process is continued to trace the entire line. By mapping the location of the pipe, it becomes possible to listen directly over the pipe for the next step: acoustic leak detection.
Our plumbers use a wireless system of headphones and a touchscreen electronic monitor for acoustic slab leak detection. To pinpoint an underground leak an advanced ground microphone is used with a wind-protected fitting. The microphone is used at points directly above the water line to identify where the sound is the loudest. This is the location of the leak. A variety of other specialised microphones can be used to suit the location of the leak, dependent on surface and whether the leak is indoors or outdoors.
