Water & Gas Leak Detection
Hidden leaks can waste thousands of litres of water, inflate your bills, and damage your home.
A dripping tap alone can waste up to 10,000 litres a year, while a running toilet can add around 9,000 litres. According to SA Water, upgrading to dual-flush toilets can save about 11 kilolitres and $36 per person annually—but undetected water leaks often cause much bigger losses.
Gas leaks are just as serious. Even a small leak can create health risks, fire hazards, and costly bills. If you hear hissing near a gas appliance, notice damp patches, or receive unusually high utility bills, it’s critical to act immediately.

FAQs
How do you find hidden leaks?
We use specialised equipment such as acoustic sensors and gas detectors to locate leaks without unnecessary damage.
Are gas leaks an emergency?
Yes, gas leaks are dangerous and require immediate attention—contact us straight away if you suspect one.
What are the signs of a hidden water leak?
Unexplained water bills, damp walls, mould, or the sound of running water when taps are off are common indicators.
How can I check for a water leak using my water meter?
First, make sure no taps, toilets, or appliances in your home are running. Then go to your water meter (usually located at the front of the property). Write down the reading on the dial or take a photo. Wait at least 30 minutes without using any water, then check the meter again.
- If the numbers have changed or the small red/black dial is still moving, it usually means water is leaking somewhere on the property.
- Common hidden leak points include toilets, underground pipes, or garden irrigation systems.
