How to Find a Water Leak
Learning how to find a water leak comes down to three checks, done in order: the meter first, the rooms second, the garden last. A meter that records movement while the house is using nothing tells you water is escaping; the hunt through the rooms then narrows down where.

Much of the housing here went up through the 1950s and 1960s. Buried supply lines of that age can weep at a joint for weeks before a bill or a damp patch gives the game away.
A licensed plumber from our Zillmere team handles whatever the checks turn up. A bill that jumps with no change in your habits is the clue that usually starts the search.
The water utility runs a program that watches for unusually high use and contacts customers where it can. Its own advice is not to count on that: read your meter yourself, because every pipe on your side of the meter is yours to look after.
Rule a Leak In or Out at the Meter
- 1
Shut Down Every Outlet
Close every tap, unwind the hose, and stop the washing machine, the dishwasher, any plumbed-in fridge and any irrigation. Not one outlet in the place should be able to draw a drop while the test runs.
- 2
Photograph the Meter
Your meter lives in a small below-ground box, set flush with the ground, generally in the verge out the front and sometimes visible in the footpath. Photograph the numbers, including the red digits, and leave the tap at the meter open so the test is honest.
- 3
Read It Again Later
Come back after a decent stretch with no water used and compare. A changed reading means water is getting out, and a licensed plumber should investigate from there. An unchanged reading clears the supply side, and the rooms and garden are your next stops.

Toilets, Taps, Showers and Appliances
Work through the inside in this order: toilet cisterns first, then the taps and showers, then the plumbed-in appliances, then the walls, ceilings and floors.
The toilet cistern
drip a splash of food colouring into the cistern and leave it without flushing. Colour reaching the bowl shows the cistern is losing water past its seal; flush afterwards and the colouring rinses away without staining the bowl.
Taps and showers
confirm each one closes fully and does not drip afterwards. A shower that keeps running after you shut it off is wasting water around the clock.
Plumbed-in gear
check the fridge water connection and the hot water system for drips or damp at their fittings.
Walls, ceilings and floors
look for damp or stained plaster, a musty smell, finishes that swell or peel, and a warm patch underfoot. On a slab, that warm patch can be water from a buried line.
Who Fixes the Leak You Find
The findings point two ways: a drip at a tap, toilet or fitting is your likely culprit. A meter that keeps moving with nothing found points to a concealed loss below the lawn, beneath a driveway or within a wall cavity.
Either way, a licensed plumber does the repair. Fixing a broken pipe is minor work under the QBCC's categories: a licensee carries it out, and neither a council permit nor a Form 4 is needed.
Urban Utilities maintains the street mains and the sewer main, but the pipes running onto your property are the owner's to keep in repair. The QBCC's unregulated list does let an owner swap a tap's jumper valve or washer, or certain cistern washers, with no plumber involved.
A concealed loss is different work, and it wastes a surprising volume of water every day it runs unseen. Our leak detection page covers how that search narrows down and who owns which pipe.
Taps, Tanks and Wet Ground Outside
Finish the hunt outdoors: the garden taps and hose fittings, any rainwater tank, and the ground itself.
Garden taps and hoses
a slow drip at an outdoor fitting wastes an enormous volume over a season, so feel around each spout and coupling while the hose is off.
The rainwater tank
confirm it is not topping itself up from the mains. A tank linked to town water can keep refilling through a faulty solenoid or internal part, and a licensed plumber checks that.
The ground
soggy soil, a lawn patch that stays greener than the rest, spongy turf and paving that has gone out of level all point to a buried line. The reactive clay under Zillmere yards swells in the wet months and dries out in winter, and that movement works old buried joints loose, so take a suspicious green patch seriously.
The pool, if there is one
stand a bucket of pool water on a step so the levels match, mark both, leave the pool unused for 24 hours, then compare. A bigger fall in the pool than the bucket suggests a leak; an equal fall is evaporation.
Hidden Leak Questions From Zillmere
Call (07) 3523 6484How do I find a water leak in my Zillmere home?
Start at the meter with nothing running, then work through the toilets, taps, showers and appliances inside, and finish with the garden taps, any rainwater tank and the ground outside. Anything the hunt cannot explain is work for a licensed plumber.
The meter moved but I can't find anything in Zillmere. What does that mean?
Water is escaping somewhere you cannot see: buried out in the yard, under a drive or behind a wall. A licensed plumber investigates that kind of loss, and our leak detection page explains how the search narrows down.
How does a plumber find a leak I couldn't?
We confirm the loss at the meter, isolate sections of the pipe run, pressure test each section, listen along the line and take moisture readings before opening anything up. The leak detection page has the detail.
Can I fix a hidden leak myself?
No, that repair belongs to a licensee. Under QBCC rules, a damaged pipe is a minor-work repair carried out by a licensed plumber with no permit and no Form 4. The unregulated list open to owners covers a tap washer or jumper valve, certain cistern washers, a shower head or a filter cartridge, and nothing more.
