Leak Detection Before Anyone Cuts In
Sydney Water says it may fix, free of charge, the water pipe between its network and your meter, though not beyond one metre inside your property boundary. Further in, we pinpoint leaks before cutting anything.

Leak Detection Services Across Rooty Hill
What could be leaking in a Rooty Hill home without a single drip on show? Any of these:
Hidden Water Leaks
Unlike a drain, a supply line stays under mains pressure, which means a hidden split leaks nonstop, and it can be too quiet for anyone in the house to notice.
Slab Leaks
Reaching a water line laid in or under a concrete slab means breaking concrete, so how precisely the slab leak is located decides how much of the floor comes up.
Underground Pipe Leaks
One strip of lawn staying green through a dry spell, or a soggy patch beside the path, can mark a buried supply line leaking between your meter and the house.
Wall and Ceiling Leaks
Before a ceiling stain appears, the water may have followed a joist or noggin, which is how the mark can end up a whole room away from the leaking pipe.
Gas Leak Detection
Suspected gas leaks call for a licensed gas fitter, who traces where the line is losing gas and makes the installation safe, with repairs done through our gas fitting service.
Pool and Irrigation Leaks
Shutting off each irrigation zone or pool line in turn and watching for the water loss to stop tells us which one has failed, so only that run needs opening.
How We Actually Find a Hidden Leak
Acoustic and thermal equipment, used in the right conditions, closes the search in on a single patch of floor:
Acoustic Listening
Our acoustic equipment amplifies the noise pressurised water makes as it escapes a crack, and moving the microphone across the floor until that noise peaks marks the spot to open.
Thermal Imaging
Heat from a split hot water line spreads into the surrounding slab or plaster, which the thermal camera shows as a bright bloom centred on where the pipe has failed.
Pressure Testing
When a sealed-off length of pipe is charged and the gauge needle falls, the leak is in that length, whereas a steady needle points the search to tapware and washers.
Drain Camera Work
Sewer and stormwater pipes buried under the yard can leak out of sight, and a camera fed along the drain line shows the cracked joint on screen before anyone digs.

Where Leaks Hide in a Rooty Hill Home
Cut the wall where the damp shows and you can still miss the pipe feeding it, so check these first:
The Meter Test
Photographing the water meter at bedtime with every tap, toilet and appliance off, then again at breakfast ahead of any showers, tells you whether your pipes are losing water overnight.
Bills That Jump
A bill higher than the same quarter last year, with no visitors, new appliance or extra garden watering to account for it, points to water escaping somewhere past the meter.
Warm Spots Underfoot
Walking barefoot across the kitchen and feeling one patch of tile noticeably warmer than the rest can mean the hot water line under that slab is leaking into the concrete.
Damp That Lingers
Mould freckling a wardrobe wall, paint bubbling along the skirting and a smell that lingers after airing all suggest a cavity staying wet, and every extra week makes it worse.

Why Finding a Hidden Leak Early Matters
Most Rooty Hill homes are freestanding, so a leak can run with no shared wall to give it away:
Nobody Shares the Wall
Rooty Hill's occupied dwellings were 76.6% separate houses in the 2021 Census QuickStats, well above NSW's 65.6%, so most homes have no neighbour through the wall to hear water running.
Water You Never Used
Litres seeping into the ground or a wall cavity never fill a kettle or bath, yet the water meter counts every one and you're billed for each until it's fixed.
Damage You Cannot See
Behind a vanity or under a floating floor, framing can swell and plasterboard soften for weeks before a mark shows, and those unseen weeks let rot and mould take hold.
Small Repairs Grow Fast
The longer a pinhole runs under concrete, the more trades the repair needs, from a carpenter for swollen skirting to a tiler for lifted floor tiles and then a painter.




How it works
Our Leak Detection Process, Start to Finish
Four steps run from your call to a tested repair, with the price agreed before a tile comes up:
Call and Book
Phoning (02) 9072 0570 and telling us what you've noticed, from a jump on the bill to a warm floor, lets us book the visit on a $0 call-out fee.
On-Site Diagnosis
At your door the plumber reads the water meter, then shuts off each fixture in turn and lets those results decide whether the acoustic or thermal equipment comes out next.
Fixed Price First
Once the leak's position is confirmed, you'll get one fixed price for the repair, with no tile lifted, no wall cut and no pipe replaced until you've agreed to it.
Repair and Retest
Through an opening no bigger than the fix requires, the faulty section is replaced, then the line is recharged and the meter watched to confirm the water loss has stopped.
Common Leak Faults We Fix
That overnight drip you've stopped hearing is still being billed, and these four faults cost you the same way:
Failing Cistern Valves
Water streaking down the back of the bowl long after the last flush can mean the cistern's outlet valve has stopped sealing, and replacing that one part ends the trickle.
Corroded Pipe Joints
Green crust or a weep around a fitting marks a corroded joint, which a short replacement section fixes, while routine maintenance can pick up the next one before it drips.
Root-Damaged Drain Lines
Roots chasing moisture push into a crack and keep widening it until wastewater seeps into the soil, and pipe relining seals that run from inside instead of trenching the yard.
Leaking Hot Water Units
If a puddle forms under the tank or the relief valve drips nonstop, have the hot water system checked, since a valve swaps out but a corroded cylinder needs replacing.

Common questions
Frequently Asked Questions
Six questions Rooty Hill households ask about cost, pipe ownership, slab leaks, leaks nobody hears, warning signs and booking:
What does leak detection cost in Rooty Hill?
It turns on where the leak sits and how long it has run, because precise location limits how much floor comes up, while a long-running pinhole under concrete can add a carpenter, tiler and painter.
Are Rooty Hill water leaks the homeowner's responsibility?
Normally, yes, as Sydney Water says you're responsible for maintaining the pipes you own, though it may repair the pipe free between its system and the meter, up to one metre inside your property boundary.
Can you find a leak under a concrete slab?
Yes, a slab leak in a Rooty Hill home is traced from the surface with acoustic and thermal equipment, and the slab is only broken once that search has narrowed to one spot.
Why can a leak in a Rooty Hill home run unnoticed?
A pressurised supply line can leak nonstop too quietly to hear, and with 76.6% of occupied dwellings here separate houses at the 2021 Census, most homes have no neighbour through the wall to notice.
Which signs point to a hidden water leak?
The signs are a water meter moving with every tap off, a higher bill than usual, warm patches on tiled floors, skirting that stays damp and shower pressure that's dropped.
How do I book leak detection in Rooty Hill?
Call (02) 9072 0570 or book online for $65 off and tell us what you've noticed, then the plumber reads your meter, shuts off each fixture in turn and prices the repair before any tile comes up.
