What Is Leak Detection?
Leak detection is the work of finding a hidden water leak and marking its exact location. A hidden leak, or concealed leak, is one you can't see, in a pipe carrying drinking water or recycled water. A leak can be any clear water that flows or trickles, or a damp patch that won't dry out. A puddle after heavy rain isn't always a leak, so rule out a leaking roof, damaged waterproofing or stormwater first.
The property owner fixes all pipes and fittings on the property. Sydney Water owns and maintains the water meter. The utility often repairs the service pipe from the water main to the meter, up to one metre inside the boundary, at no charge. According to Sydney Water, a licensed plumber needs to fix a leak between the water meter and the building. A toilet that runs constantly can waste thousands of litres a day, by Sydney Water's figures.
Professional Leak Detection and Repair in Sydney
We Find It Leak Detection offers professional leak detection and leak repair across Sydney, and every service below has its own page, from hidden leaks to burst pipes:
-
Water Leak Detection
Get a quoteA water meter leak test shows whether water is escaping before the search starts. Then our water leak detection traces the hidden leak inside walls, under slabs, in ceilings or in underground pipes.
-
Non-Invasive Leak Detection
Get a quoteLocating the leak first uses an acoustic listening device, a microphone that hears water escaping a pressurised pipe. Tracer gas is a method that pushes a safe gas through the pipe to find where the gas escapes. A pipe locator is a device that finds where a pipe runs.
Using non-invasive leak detection, the team marks the leak before anything is opened, so the opening goes only at the mark. Cutting into walls to search opens the wall before anyone knows where the leak is. Detection first suits a leak nobody can see, while a visible leak needs no search and goes straight to repair.

If the marked leak sits in a pipe, we repair the damaged section and retest the line. That fix, slab leak repairs included, comes under leaking pipe repairs.
Flexi hoses caused one in ten of Suncorp's home insurance claims in 2025. Our flexi hose replacement swaps out the part behind those claims. Standards Australia added flexible hose rules to the 2025 edition of AS/NZS 3500.1, the water services standard, to cut the risk of a flexible connector failing.
-
Commercial and Strata Leak Detection
Get a quoteWe trace water leaks for strata buildings, high-rise buildings, businesses, builders and property managers. Insurance leak reports also come under our commercial leak detection.
Sydney Water's free repair zone runs to the master strata property boundary for units. Every strata lot owner belongs to the owners corporation, which NSW law requires to repair and maintain the common property. Our strata leak detection works out which leaks the owners corporation has to fix.

Water getting in around a shower slips past the grout, the shower base or a worn seal and shows up in the next room or the ceiling below. We locate the failing part and show you which one it is before any tile comes up. Our leaking shower repairs cover shower leak detection, regrouting and resealing, and upstairs bathroom leaks.
-
Burst Pipe Repair
Get a quoteFirst, turn off the meter tap beside the water meter if a burst pipe is spraying or flooding the floor. From there, burst pipe repair means finding the split section of pipe and replacing it.
-
Gas Leak Detection
Get a quoteOur gas leak detection finds where gas is escaping from the gas pipes at homes and businesses. Jemena says a smell like rotten eggs or cabbage can signal a leak.
If you suspect a gas leak, turn off anything that could ignite the gas, then leave the area. Report the leak to Jemena, which takes reports at any hour, 7 days a week.
-
Emergency Leak Detection
Get a quoteWhen water is spreading through the house, call the team that's open 24 hours for same-day emergency service. Day or night, a real person answers the phone. Our emergency leak detection is for a leak that can't wait, such as a meter that keeps moving with every tap off.

Frequently Asked Questions
Can Sydney Water Fix Water Leaks for Free?
No, Sydney Water doesn't fix water leaks in the pipes and fittings on the owner's side, which the property owner fixes. Sydney Water owns and fixes the water meter. The utility's free repairs often cover the pipe between the water main and the meter too, up to one metre inside the boundary. For a quick check, turn off the meter tap, and if the leaking water stops, the leak is in your own pipes. Sydney Water may fix a leaking meter or meter tap, or a pipe leaking between the meter and the street. Sydney Water's faults line, 13 20 90, takes those reports 24/7. Meter taps are the owner's to fix, yet Sydney Water repairs a faulty meter tap free within 10 working days when you call the faults line. Sydney Water charges a fee to find a hidden leak on the owner's side, through WaterFix Concealed Leaks.
How Much Does Leak Detection Cost in Sydney?
Sydney Water charges $450 for the first hour and $130 per extra half-hour for leak detection, GST included, under a WaterFix Concealed Leaks schedule dated 26 September 2025. The fee falls to $260, GST included, under the same 2025 Sydney Water schedule when the leak is obvious or none is found. The price depends on how long the search takes. Repairs aren't included: Sydney Water quotes them separately and welcomes quotes from other licensed plumbers. We Find It Leak Detection charges a $0 call-out fee. Every job gets the price in writing before any work begins. You get Best Price Guaranteed on that written quote.
Is Water Leak Detection Worth It?
Yes, water leak detection is worth it when the meter shows a leak that nobody can see. Locating and marking the leak first means the opening goes only where the leak is. Fixing the leak can also earn the hidden leak allowance, a credit on the water bill, when a licensed plumber or qualified technician does the work.
Who Can Find a Hidden Water Leak in My House?
A leak detection specialist finds a hidden water leak when the meter shows a leak you can't locate. Not every plumber has the tools and skills to track down leaks underground or inside walls. A licensed plumber makes the repair, because homeowners may legally do only minor jobs, such as swapping a tap washer. NSW requires a licence or certificate for all plumbing work, regardless of the cost.
What Are the Signs of a Hidden Water Leak?
The signs of a hidden water leak are a rising water bill, damp walls that won't dry, greener lawn patches and a meter that keeps ticking with every tap off. A rising bill only points to a leak when your water use stays the same. The water meter leak test starts with every tap and water-using appliance off and the meter tap left on. Note the reading on the dial, then use no water for at least an hour. Any change on the dial means a leak, and a larger change points to a larger leak.
Will I Get Money Back on My Water Bill?
Yes, after a licensed plumber or qualified technician repairs a hidden leak, Sydney Water credits your water bill with 50% of the water usage charge from the worst-affected quarter. Each property can receive the allowance once every 5 years. The claim has to go in within a year of the repair. Sydney Water's hidden leak allowance rules add two more conditions: the owner couldn't see or hear the leak, and the owner maintained the water service. Visible leaks don't qualify, including damp soil, grass that stays wet, and leaks from washing machines, dishwashers, toilet cisterns or taps. The claim needs the licence number of whoever did the repair, where applicable, and the invoice. Residential and non-residential property owners both qualify. Our high water bill investigation looks for the leak behind a bill that has jumped.
How Do I Book Leak Detection in Sydney?
Booking leak detection takes two steps, noting the meter reading and when the bill rose, then calling (02) 9073 7896. A real person answers that call 24 hours a day, then books Same Day Service.
