Leak Detection in South Western Sydney
South Western Sydney's heavy clay ground hides leaks extremely well, which is why so many are found on a water bill rather than by anyone spotting water. Around Liverpool, Fairfield and Cabramatta, decades-old buried copper and galvanised services run under driveways and concrete paths that generations of ground movement have already cracked. Newer estates at Prestons, Casula and Edmondson Park are slab-on-ground with in-slab hot water lines and high mains pressure, a combination that turns a small weakness into a steady leak. Camden's acreage properties are different again, where a leak on a long buried line quietly drains tank storage or runs a pump continuously. We confirm loss at the meter, locate with acoustic and thermal equipment, then open one small access.

How we handle leak detection in South Western Sydney
1. Isolate and pressure test
We shut off sections of the system and watch the meter and gauge. That confirms there really is a leak, tells us whether it is on the hot or cold side, and narrows it to a section of the property before anything is opened up.
2. Acoustic and thermal location
Acoustic equipment listens for the sound of water escaping under slabs and paving, while thermal imaging shows temperature patterns through floors and walls. Together they pinpoint the leak rather than leaving us to guess a metre either way.
3. Non-destructive access
Once the leak is marked, we open the smallest area that lets us reach it, whether that means a single tile, a small slab core or a neat wall access panel, instead of demolishing a bathroom to find one pipe.
4. Repair and verify
We repair the failed section, re-pressurise the system and re-check the meter with everything closed. You get a report showing where the leak was, what caused it and confirmation the system now holds pressure.
Every job is quoted on site and agreed in writing before work starts, so there are no surprises.

Recent leak detection jobs in South Western Sydney
Concealed main, Liverpool
A meter that never stopped moving with all taps off pointed to the buried service. Acoustic tracing found the split beneath a concrete path, and we cut one small section rather than the full path.
In-slab leak, Casula
Skirting boards along one wall stayed damp in a newer home. Thermal imaging showed a hot water line leaking inside the slab. One cored access allowed the repair, then we re-tested pressure.
Pump running constantly, Camden
A rural property's pressure pump cycled all night. Isolating sections proved the loss was on the buried line to the shed, which we located, repaired and pressure tested before recommissioning.
