Water Leak Detection. Reinvented.

For decades, leak detection has been stuck in the past – slow, expensive, and often unreliable. Old-school methods like hydrogen tracer gas testing, thermal imaging, concrete moisture meters and basic acoustic devices have been the industry standard, but they’re time-consuming and costly for customers.

We’ve changed the game. Using the latest advancements in detection technology, we can locate leaks in half the time of traditional approaches – saving you both time and money. And here’s our promise: If we don’t find your residential leak, you don’t pay.

From Hidden Hiss to Exact Location

leak detection central coast and sydneyWhen a pressurised water pipe leaks, it produces its own signature sound – anything from a faint hiss from a pin-sized hole to a steady rush from a larger crack. These noises send subtle vibrations along the pipework and into the surrounding ground. They’re silent to the human ear, but our advanced equipment can detect them with pinpoint precision.

Our highly trained technicians test multiple points along the suspected pipe run, using equipment designed to filter out background interference from traffic, wind, or machinery. This allows us to focus solely on the specific sound frequencies created by water escaping under pressure. By comparing sound levels from different locations, we can identify the exact spot where the leak is strongest. Our new technology allows us to confidently mark an ‘X’ on a specific spot and say – ‘Your leak is right here’.

This precision means faster results, less disruption to your property, and a cost-effective repair process – all backed by our no-find, no-fee guarantee.

How We Detect Leaks

At Leak Detect Pro, we combine Sewerin acoustic listening and our proprietary air-manifold pressure system to find underground leaks with exceptional precision. Our technicians test along the suspected pipe run, detect the faintest vibration frequencies, and isolate leaks while filtering out background noise – all without damaging your property.

  • Your water meter is spinning when everything is off

  • Unexpectedly high water bills

  • Soft or wet spots in your lawn or garden
