High Water Bill Diagnosis & Hidden Leak Solutions
Unusually High Water Bill? You May Have a Hidden Leak
Have you received a surprise water bill that’s double or even triple your usual usage — with no visible signs of a leak? You’re not alone.
At Local Leak Detection Specialist, we specialise in helping homeowners, landlords, tenants, and property managers across Sydney, Illawarra, Southern Highlands, and Shoalhaven quickly diagnose the cause of excess water usage.
Our non-invasive leak detection services identify whether the problem is a hidden underground pipe leak, a slow drip in the slab, or a leak in the wall or ceiling — often before any visible signs appear.
Common Hidden Leak Locations That Cause High Bills
- Underground pipes between the meter and your house
- Leaking irrigation or reticulation systems
- Buried copper or poly service lines
- Leaks under tiled bathrooms, kitchens, or laundries
- Pipes leaking into wall cavities or under floors
- Faulty toilet cisterns or constant trickle leaks
- Slow leaks in strata unit common areas
Even a pin-hole leak in a concealed pipe can waste hundreds of litres per day — costing you dearly over a quarterly billing cycle.
Our Hidden Leak Detection Process
We use advanced, non-destructive tools to pinpoint leaks without breaking tiles, digging trenches or removing plasterboard.
Our equipment includes:
- Acoustic listening devices – to identify pressurised pipe leaks underground or in walls
- Thermal imaging cameras – to detect warm/cool water movement
- Tracer gas systems – for silent leaks under slabs or driveways
- Moisture meters & mapping – to verify areas of water ingress or saturation
- CCTV inspection cameras – for pipes or areas with restricted access
- Digital pressure drop testing – to confirm leak presence from the meter
We also perform meter tests to confirm:
- If water is passing through the meter when all taps are off
- If the issue lies between the water meter and the building
- If the problem is internal, in hot or cold water lines
