A leak that stays out of sight wastes water around the clock, under a floor, behind a wall or beneath a driveway, and the first hard evidence is often a bill that makes no sense. Our water pipe repairs page sets out the whole supply line from the street to your taps, and burst pipe repairs covers the ones that announce themselves.

Signs of a Leak You Cannot See
A hidden leak shows itself in three spots: the meter box, the house and the yard. A bill that jumps without explanation is the thread that usually joins them.
Meter box
the dial creeps even with every tap in the house shut.
House
damp or stained plaster on walls and ceilings, a stale musty smell, paint that bubbles or peels.
Yard
ground that stays wet, or one strip of lawn outgrowing the rest.
Bill
usage that climbs though your habits have not.
The interwar supply lines through this suburb are mostly galvanised steel. Rust builds inside these pipes and eats the threaded joints first, so the pipe narrows before anything drips. Weak flow at the far end of a Wilston Road house often arrives ahead of any stain.

From Meter Reading to the Exact Pipe
We work through the line in order: confirm the leak at the meter, split the pipe run into sections, pressure-test each section, then narrow down to one length before opening anything.
- Isolation valves let us test one stretch of pipe at a time.
- A pressure test shows which stretch is losing water.
- Our plumber puts an ear to exposed pipe or wall to catch the sound of water moving.
- Moisture readings taken across walls, floors and subfloor timbers map where the water sits.
- A licensed plumber runs the whole search and the repair that follows.
One length gets narrowed down, and only then does anything get opened. That keeps the digging where the leak actually is.

Check Your Water Meter Before You Call
Shut every tap and water-using appliance, write down the meter numbers, wait at least one hour, then read the meter again. Movement in the numbers means water is being drawn somewhere it should not be.
- Turn off taps, hoses, the washing machine, the dishwasher, a plumbed-in fridge and any irrigation.
- Photograph the meter face with its red numbers showing, so nothing relies on memory.
- Keep the meter tap open and draw no water for at least one hour.
- Read the meter again. Any change in the numbers points to a leak.
The test also tells you which side of the meter the problem sits on. A flooded meter box belongs to Urban Utilities, and soggy ground beside a stopped meter suggests the utility's main. A dial that keeps turning means the leak sits on your side of the meter, and that is where a licensed plumber comes in.

Water Bill Relief for a Hidden Leak
A concealed leak, one hidden from view on the property side of the meter, can qualify for a bill adjustment from Urban Utilities. The claim needs the repair finished inside the utility's deadline and a licensed plumber's invoice to support it.
What counts
water escaping below ground, inside concrete or under a building, where no owner could reasonably have known.
The deadline
the repair needs to be finished inside a month of finding it.
The claim
the account holder applies in writing with the plumber's invoice attached.
What never counts
dripping taps, running toilet cisterns, hot water systems and other appliances, irrigation and outdoor water features.
If Urban Utilities alerts a tenant to a possible leak, notice reaches the owner or agent that day, and the deadline starts from there. Read the meter yourself rather than waiting for the utility to flag a spike.

Where Older Pipes Hide Their Leaks
Pre-war walls along Thomas Street hold galvanised fittings that rust from the inside. Split under pressure, one of those fittings sends a sudden pool to the base of a wall, and that pool is usually the first clue an owner gets.
Leak detection in Grange often comes down to age: the original galvanised run inside the wall, copper branches added later, and the long stretch out to the boundary. Where the pipe itself is past saving, our repiping old pipes page sets out the options, and flexi hose replacement covers the braided lines under vanities and basins.

Hidden Leak Questions Answered
Call (07) 3523 7172How long does the water meter test take?
At least one hour, with nothing in the house or garden drawing water while you wait. Shut every tap and appliance first, note the meter numbers, red numbers included, then compare after the hour. Any movement means a leak, and a licensed plumber should check next.
Is a leak at my meter my problem or the water utility's?
A stopped meter with soggy soil beside it points to the utility's main, and a flooded meter box goes to Urban Utilities as well. A dial that keeps turning means the leak sits past the meter, on your side of it, and that side is our work.
What does leak detection cost?
The price depends on access, how much pipe needs testing and the method the job calls for, and a fixed quote settles it before we start. Whether the line runs inside a wall, under a slab or through the ground moves the figure most.
How quickly do I have to fix a hidden leak?
Within one month of discovery, if you want the bill adjusted. Urban Utilities counts a concealed leak as repaired only inside that window, and the claim needs a licensed plumber's invoice attached. Book the repair as soon as the meter test confirms the leak.
Who pays for a hidden leak on my property?
The owner does. Every pipe and fitting past the meter onto the property is yours to maintain, and you pay for all the water the meter records, leaks included. Relief exists only under the utility's concealed leak rules, so run the meter test early.
