Hidden water leaks are one of the most damaging things that can happen inside a home. The problem is, you often don’t know they’re there until the damage is already done. By the time you spot water stains, mould, or a spike in your water bill, the leak could have been running for weeks or months.
Here are seven signs that should have you calling a licensed plumber Melton sooner rather than later.
1. Your Water Bill Has Gone Up Without Explanation
If your water usage hasn’t changed but your bill has jumped, something is using water that shouldn’t be. A slow leak inside a wall or under a slab can waste thousands of litres every month without a single drip being visible.
2. You Can Hear Running Water When Everything Is Off
Turn off every tap, appliance, and fixture in the house. If you can still hear a faint hissing or running water sound, especially near walls or floors, there’s a good chance water is moving somewhere it shouldn’t be.
3. Damp Patches, Staining, or Discolouration on Walls or Ceilings
Yellow or brown watermarks, bubbling paint, or soft patches on plasterboard are all signs of ongoing moisture. These don’t appear overnight. If you’re seeing them, the leak has likely been active for some time.
4. Mould in Unexpected Places
Mould in a bathroom or laundry is common. Mould on an interior wall, behind furniture, or in a corner of a room that shouldn’t be wet is not. Persistent mould growth away from obvious moisture sources points strongly to a hidden leak.
5. Hot Spots or Cold Patches on Your Floor
If you walk across a tiled or concrete floor and notice an unusually warm section, it could indicate a hot water pipe leaking beneath the slab. Cold, damp patches can indicate a cold-water line doing the same.
6. Low Water Pressure Throughout the House
A sudden or gradual drop in water pressure across multiple fixtures, not just one tap, can mean water is escaping somewhere in the main supply line before it reaches your taps. This warrants investigation from a licensed plumber.
7. Your Water Meter Is Moving When No Water Is Being Used
This is the simplest test you can do at home. Turn off every tap and appliance. Go to your water meter and watch the dial. If it’s still moving, water is going somewhere. Don’t ignore it.

Frequently Asked Questions
How do I know if my water bill increase is caused by a hidden leak?
Turn off every tap and appliance, then check your water metre. If the dial is still moving, water is escaping somewhere. A bill increase of 20% or more with no change in household habits is a strong indicator of a hidden leak.
Can a hidden water leak cause structural damage?
Yes. Water leaking inside walls, under slabs, or beneath flooring saturates building materials over time, causing softening of plasterboard, rotting of timber framing, and mould growth. In slab-on-ground homes it can eventually affect the foundation.
How long can a hidden water leak go undetected?
Hidden leaks can run for months or even years without being noticed, particularly slow leaks in areas that aren’t regularly checked. Monitoring your water metre and bills is the best way to catch them early.
Is mould always a sign of a hidden water leak?
Not always. Mould in bathrooms and laundries can result from condensation. However, mould appearing on interior walls, behind furniture, or away from obvious moisture sources is a strong indicator of a hidden leak rather than surface dampness.
What should I do if I suspect a hidden water leak?
Run the water metre test to confirm water is escaping, then call a licensed plumber with professional leak detection equipment. Do not delay — every day a hidden leak runs, the damage and repair cost increases.
