A leak that stays hidden does the most damage. Sooner or later it announces itself as a stain, a warm patch of floor or a bill that climbs for no reason you can see.

Tracing Hidden Leaks Close By
Locating a leak is a job for evidence rather than luck: meter readings, isolated pressure tests and a methodical trace outward from the known point.
Only when the exact spot is pinned down do we open the smallest patch of wall, floor or paver the repair actually needs.

Why Hidden Leaks Thrive Here
A few things about the housing stock and the ground here keep a drip off your radar for months. They shape how every trace gets run.
Mostly houses, mostly on slabs
The 2021 census recorded 74.3 per cent of local homes as separate houses, and most of these brick builds rest on concrete slabs. A fault under the slab has nowhere visible to go, so the first sign can be a lifting tile or a floor patch that no longer sits flat.
The land drains toward the creeks
The state soil atlas describes this as gently sloping country, so water escaping a buried line travels downhill with it. Pooling at the low end of a backyard off Marsden Road can point to a break much further up the yard.
Wet weather gives it cover
With an average of 1,130 millimetres of rain a year, a slow drip at a garden line or a pool top-up disappears into the wet-season numbers. A dry spell is usually when it finally stands out.

The//[WE-WILL-REPLACE-THIS]//Method We Use
Every call runs through the same sequence, and each step narrows the search until the exact point is known. Guesswork never gets a wall opened.
Meter and Isolation Checks
The water meter tells you about a hidden leak faster than any stain, so we read it, close every tap, and watch whether the dial keeps turning while nothing is running.
Supply Line Tracing
We isolate sections of the supply, watch the pressure, and narrow a fault down to a single run before any wall, paver or floor tile gets opened up.
Wall and Slab Leaks
Mains pressure pipes run inside wall cavities and under slabs here, so we chase the sound, the damp and the temperature clues right to the point before opening surfaces.
Outdoor Lines and Sheds
Irrigation lines, pool top-ups and the tap behind the shed all leak quietly for years, and we trace each outdoor run separately so your bill stops carrying water you never used.

Common Signs of a Hidden Leak
Four things in particular bring people to call us. Each one means water is going somewhere it should not.
The Bill Crept Up
A bill that rises with no change in habits means water is escaping somewhere out of sight, and a simple meter test settles the question in minutes.
Stains That Keep Spreading
Plaster or carpet stains that grow despite dry weather point to a pipe inside the cavity, and we trace them back to the exact fitting at fault.
Sounds of Running Water
A hiss or trickle when every tap is closed means water is still moving through a supply line, and following that sound through the house usually lands us close to the point.
Warm Patches Underfoot
A warm stretch of floor slab with no hot tap running means the hot line underneath is weeping, and that heat is quietly soaking into your power bill too.

Why a Small Leak Matters
Tracing early costs less by every measure: the opening stays small, the materials stay dry and the repair stays simple.
The bill keeps running
Water is metered before it reaches the break, so a leak past your meter charges you by the litre, quarter after quarter.
Damage spreads quietly
Plaster holds moisture, architraves swell and mould takes hold behind furniture long before you see the surface stain. By then the repair list is longer.
Small becomes sudden
A weeping joint can sit in a wall for months, then let go under pressure. If a slow leak has just gone loud, see our burst pipe page while you wait for the plumber.

Leak Questions Answered
Call (07) 3523 6428How do you find a leak without opening every wall in a Kallangur home?
We use the water meter, pressure testing and line tracing to narrow a leak to one spot first, so we only open the small patch of wall or floor the repair needs.
Does the Unitywater meter show a hidden leak?
Yes, a Unitywater meter still turning while every tap in the house is closed points to a leak on the property side, and a bill that jumps without explanation is worth checking.
What drives the cost of a leak trace?
The cost comes down to how deep the leak sits and how much tracing it takes, and the fixed quote you approve before work starts is the figure you pay, whatever we find.
Does wet ground near Freshwater Creek make leaks show sooner?
It can, because soil beside the creek and the mapped flow paths stays saturated through the November to March storms, and a buried leak shows faster in wet ground.
Is a leak on my property mine to fix, or Unitywater's?
Unitywater maintains the public mains under the street, and the pipes beyond the connection belong to the owner, so we trace and repair those private runs for you.
