How to Find a Water Leak
Your water meter tells the truth about leaks: it counts every litre the property draws, and it cannot be fooled. Learning how to find a water leak starts there, because a bill that climbs while your habits stay the same is the first hint most people get.

Around Fortitude Valley, festival weeks add a wrinkle of their own. BIGSOUND and the Valley Fiesta weekends push venue kitchens and amenities flat out, so a spike on your bill can read as festival trade rather than a leak.
The checks below settle that question. You need nothing beyond a phone camera and a bottle of food colouring, and a licensed plumber takes over once every check comes back clean.
Start With a No-Use Meter Check
- 1
Close Every Outlet
Shut all the taps, the hose, the washing machine, the dishwasher and any irrigation. Any fridge with its own water line gets closed off too. The stop tap at the meter stays open, because the test needs supply through to the property.
- 2
Record the Numbers
Photograph the full dial, red digits included, since those small wheels pick up the tiniest draw. Urban Utilities meters around Brisbane sit in a low box flush with the verge between the road and the boundary.

Wait Through Dead Hours
Give the test a full hour or more, during a stretch when nothing on the property should be drawing water. A leak pulls water around the clock, so quiet hours expose what a busy day hides.

Read and Compare
Match the dial against your photo. Movement there, with the house shut down, is your answer: water is getting out somewhere it should not be.

Where Water Hides in the Yard
Three checks cover the yard: drip-test the garden taps and hose fittings, watch a rainwater tank for mains top-ups, and read the ground for soggy or unusually green patches.
Garden taps and hoses
a slow drip at a hose fitting wastes thousands of litres over time, so feel behind the tap head and along the length of the hose.
Rainwater tanks
a tank linked to town water can keep refilling through a faulty solenoid or internal part, which hides the real problem. A licensed plumber checks that part.
The ground
soggy lawn, spongy soil or paving gone uneven all point to water under the surface.
One thing worth knowing before you dig: the Valley was built on a marshy flat, and the groundwater beneath it runs shallow. A damp verge can be wet ground rather than a wet pipe, so trust the dial over the lawn.
If your place has a pool, the bucket check settles it. Sit a bucket of pool water on a step with both levels matched and marked, leave it a full day with no swimming, then compare. A pool that dropped further than the bucket is leaking; an even fall is just evaporation.
Room by Room Inside the House
Indoors the order matters: toilet cisterns first, using the dye test, then every tap and shower, then plumbed-in appliances, and last the surfaces where hidden water shows itself.
The Toilet Dye Test
Drip a few drops of food colouring into the cistern and leave it alone, with no flushing. Colour drifting into the bowl after a wait says the cistern is letting stored water past its seal. Flush when the test is done, because the dye will not mark the ceramic.
Fixtures and Appliances
Shut each tap and shower off hard and watch for a slow drip. Look under the plumbed-in fridge and around the hot water system for water that should not be there. In tower apartments the services pack into tight corners, so one unit's leak often shows up as the stain on the ceiling below.
The Surfaces Water Leaves
Hidden water leaves marks you can read from across the room:
- stains creeping across a wall or ceiling
- paint or timber finishes swelling or peeling
- a stale, damp smell hanging in one spot
- one patch of floor that stays warm, which can mean a hot pipe under the slab
Meter Moving but Nothing Found
A culprit you can see, at a tap, a toilet or a fitting, explains the movement, and the fix is straightforward. A dial that keeps turning when every check comes back empty points to a concealed leak, underground, beneath a driveway or inside a wall.
Everything from the meter onto the property is yours to maintain, concealed leaks included. Repairing a broken or damaged pipe falls into the minor work category, which Queensland law gives to a licensee alone.
When to Bring in a Plumber
Call us once the dial proves a loss the hunt cannot locate. We confirm at the meter, isolate the property run by run, pressure-test each section, then listen along the pipe and take moisture readings before a single lining gets opened. The leak detection in Fortitude Valley page carries what your meter result says about whose pipe is at fault.
Hidden Leak Questions From Around the Valley
Call (07) 3523 6484How long should I wait before reading my Fortitude Valley water meter again?
At least one hour, with nothing in the house drawing water. A leak pulls water around the clock, so a quiet window shows what a busy afternoon hides. Any movement across that hour points to a loss worth chasing.
Who is responsible for a hidden leak in Fortitude Valley?
The property owner, for every pipe and fitting on the property side of the meter, concealed leaks included. Urban Utilities maintains the public mains and the street-side sewer. A renter who suspects a leak should report it to the owner or agent straight away.
How do plumbers find a leak I cannot see?
First the meter confirms the loss, then we isolate sections of the supply and pressure-test each one. We trace the sound down the pipe and take moisture readings through linings before anything gets opened. The detail sits on our leak detection page.
Can I fix a hidden leak myself?
No, repairing a broken pipe is minor work for a licensee alone under Queensland law. Only the QBCC's short unregulated list stays open to owners: a tap washer or jumper valve, or the washers inside a toilet cistern.
