Warning Signs of Hidden Water Leaks

1

Constantly Spinning Water Meter

If all taps and appliances are off but your water meter’s dial keeps moving, it signals water is escaping somewhere within your property’s plumbing system.

2

Unexpected Rise in Water Bills

A sudden increase in your Barwon Water quarterly charges without higher usage often points to an underground leak or main line failure.

3

Warm Spots on Floors

Feeling isolated warm areas on tiled or timber floors usually indicates a ruptured hot water pipe beneath the surface or slab.

4

Damp Walls and Mildew

Persistent damp patches, peeling paint, or musty odors along walls suggest water is seeping into cavity spaces, causing hidden damage.

How Non-Invasive Leak Detection Works

Precision tools reveal hidden leaks without damage

Acoustic Ground Microphones

Amplifying water leak sounds beneath surfaces

High-frequency microphones detect escaping water noises under concrete and soil to locate tiny pipe ruptures.

Thermal Imaging Cameras

Spotting temperature changes from moisture buildup

Infrared cameras identify heat variations caused by water pooling inside walls and under floors.

Tracer Gas Testing

Pinpointing micro-fissures with safe gas mixtures

Non-toxic hydrogen and nitrogen gases reveal exact leak points by surfacing through cracks for sensor detection.

    No demolition is needed; tools like infrared cameras and acoustic sensors locate leaks through existing surfaces without cutting drywall or lifting floorboards.
