5 Signs You Have a Hidden Water Leak

Hidden water leaks are one of the sneakiest problems in any home. By the time you see visible damage — stained ceilings, warped floors, or mould — the leak may have been quietly running for weeks or months. Catching a leak early can save you thousands in repair bills.

Here are 5 signs you might have a hidden water leak in your home.

1. Unexplained Rise in Your Water Bill

If your water usage habits haven't changed but your bill has jumped noticeably, that's a red flag. Even a small, slow leak can waste thousands of litres per month. Check your bill against previous months — a consistent upward trend with no explanation is worth investigating.

2. The Sound of Running Water (When Nothing's On)

Stand quietly in your home and listen. If you can hear water running — a faint hissing, dripping, or flowing sound — but all taps and appliances are off, you may have a leak inside a wall, under the floor, or underground.

3. Damp Patches, Stains or Mould

Discolouration on walls or ceilings, soft or spongy flooring, or unexplained mould growth can all indicate water is accumulating somewhere it shouldn't be. Pay close attention to areas near bathrooms, laundries, and kitchens.

4. Low Water Pressure

A sudden or gradual drop in water pressure — especially in specific areas of the home — can indicate a leak in your supply lines. If the drop is throughout the whole house, it could be a main line issue.

5. Your Water Meter Is Moving With Everything Off

Turn off every tap, appliance, and irrigation system in your home. Then check your water meter. If the dial or digital display is still moving, water is flowing somewhere — and it's almost certainly a leak.
