Where Hidden Water Leaks Show Up
A hidden leak is usually noticed somewhere other than the pipe itself: a damp wall, a lifting floor, a wet patch or a bill.
Inside A Wall
Water pipes run inside walls to every tap and shower. A leak there shows as damp plaster, bubbling paint or skirting boards that start to lift.
Under A Floor
Water from a pipe under a kitchen, bathroom or laundry floor soaks into timber and laminate, which swells and lifts at the joins.
Wet Carpet, Nothing Spilled
A damp patch in the carpet that keeps coming back, with nothing spilled, is water reaching it from a pipe you cannot see.
Underground, Outside The House
The water service runs underground from the meter to the house. Sydney Water says a greener patch of grass than the lawn around it can mean an underground pipe leak.
A Joint That Weeps
A pipe joint that leaks a little at a time leaves a white mineral trail and a damp patch long before anyone sees water.
How Urgent Is Your Leak?
Three signs of a hidden water leak, from most to least urgent, and what to do about each.
Water Spraying Or Coming Through The Ceiling
Turn the water off at the meter. If water is near a light or power point, turn the power off at the switchboard too, then call us. Our emergency service runs 24/7.
A Damp Patch, Stain Or Lifting Floor
Water is getting out where you cannot see it, and damp walls, floors and ceilings get worse. If the patch is under a bathroom, our dye testing page explains how the shower, bath and toilet above are checked.
A Water Bill Higher Than Usual
Turn off every tap and appliance that uses water, note the numbers on the meter and use no water for an hour. Sydney Water says that if the numbers have changed, you have a leak.
How We Find And Fix A Hidden Leak
From the sign you can see to the pipe that is leaking, with the price agreed before the repair.
Leak foundFind The Leak
We start where you have seen the sign and work back to the pipe or fitting the water is coming from, using a pressure test, a dye test, or acoustic or nitrogen tracer-gas leak finding to suit the leak. Then we show you what we found.
Price agreedOne Fixed Price To Fix It
You get one fixed price for the repair before any work starts, and it does not change while we work. Our leaking pipe repairs page covers the repair in detail.

Water Leak Detection FAQs
Answer:
Common signs are a water bill higher than usual, a water meter that keeps moving with every tap off, damp or bubbling walls, skirting boards or floors that lift, a stain on the ceiling, or water you can hear running when nothing is on.
Answer:
Sydney Water's steps: turn off every tap and appliance that uses water, note the numbers on the meter, then use no water for at least an hour. If the last numbers have changed, you have a leak, and the bigger the change, the bigger the leak. Leave the tap at the meter turned on while you test.
Answer:
It depends on where the signs are. We use pressure testing to check whether a water line is holding pressure, dye testing for showers, baths, toilets and floor wastes, and acoustic or nitrogen tracer-gas leak finding to trace a leak in a pipe you cannot see. No one test suits every leak, so we choose the one that fits what you are seeing.
Answer:
It depends on the signs, the size of the property and how hard the pipes are to reach. Tell us what you are seeing and you get a fixed price before we start. Nothing is charged until you accept it.
Answer:
Sydney Water offers a hidden leak allowance: a credit of 50 percent of the water usage charge for the most affected quarter, when a licensed plumber or qualified technician finds and repairs a leak you could not see or hear. You apply within a year of the repair, with the plumber's invoice, and a property can get one allowance every five years. Visible leaks, such as taps, toilet cisterns, dishwashers and washing machines, do not count.
Answer:
Sydney Water says the property owner is responsible for the pipes and fittings on the property, and Sydney Water is responsible for the water meter, which it owns. Sydney Water often repairs the pipe between the water main and the meter.
Answer:
Water spraying, pouring or coming through a ceiling is. Turn the water off at the meter, turn the power off at the switchboard if water is near lights or power points, and call us. A slow leak is not an emergency, but book it soon, because damp walls, floors and ceilings get worse.
Answer:
Sometimes a small section of wall, floor or ground has to be opened to reach the pipe. We tell you what needs opening before we start, and patching and painting afterwards is usually separate work.
Answer:
A dye test is one of the ways we find a leak from a shower, bath, toilet or floor waste: coloured water goes in, and the colour shows up where the water is escaping. Leak detection is the whole job of finding a hidden water leak, wherever it is: in a wall, under a floor, in a ceiling or underground.
