Water Leak Detection Sydney, Find It Fast, Fix It Right

Blue Rhino Plumbing provides water leak detection services for homes and businesses across Sydney.
We trace leaks in the pipes inside your walls, under a concrete slab, beneath tiled floors and along the underground water line between the meter and the house.
Our plumbers use thermal imaging, acoustic listening equipment, ground microphones, drain cameras and pressure testing, so in most homes we can find the leak without opening a wall or breaking concrete.

Signs You Have a Hidden Water Leak

A leak does not always leave water on the floor. A pipe can leak inside a wall, under a slab or under the garden for weeks before you see any mark. If any of these signs sound familiar, you may have a hidden leak that needs finding:

  • Your water bill has gone up and the way you use water has not changed.
  • You can hear water running when every tap in the house is turned off.
  • A wall, ceiling or floor has a damp patch, a soft spot or a stain.
  • A tiled floor or a concrete slab feels warm in one spot.
  • One part of the lawn or garden stays green, lush or boggy when the rest is dry.
  • The outdoor concrete has a water mark that does not dry out.
  • The water meter keeps moving when nothing in the house is using water.

If you notice any of these, call us. The sooner a hidden leak is found, the less water damage it causes and the smaller the repair usually is.

How to Check Your Water Meter for a Leak

Sydney Water sets out a simple test you can do yourself before you call a plumber. Turn off every tap and every appliance that uses water, including the dishwasher, the washing machine and any drip irrigation. Leave the tap at the meter turned on. Write down the numbers on the meter, do not use any water for at least an hour, and then read the meter again. If the numbers have changed, you have a leak, and the bigger the change, the bigger the leak is likely to be.

The meter test tells you that water is escaping somewhere. It does not tell you where. When the leak is inside a wall, under the floor or underground, you will need a plumber with leak detection equipment to find it.

How We Find Hidden Leaks

The days of cutting open walls and lifting floors to find a leak are largely behind us. We use a combination of specialist detection equipment to pinpoint leaks accurately before any repair work begins, which means less disruption to your home and a faster, more targeted fix.

  • Thermal imaging cameras: Water that escapes from a pipe changes the temperature of the plaster, timber or concrete around it. A thermal imaging camera shows those temperature differences, so we can see where moisture is sitting behind a wall or under a floor without touching the surface. Thermal imaging works particularly well on hot water pipes and on pipes that run through a slab.
  • Acoustic listening equipment: Water escaping from a pressurised pipe makes a sound that you cannot hear but our acoustic equipment can. We place the equipment against walls, floors and the ground above the pipe and follow the sound to the point where it is loudest. This lets us narrow a leak down to a small area, often within a few centimetres.
  • Ground microphones for underground pipes:For a leak in the underground water supply or an irrigation line, we place ground microphones at intervals along the pipe to pick up the sound of the leak and work out where it is coming from. Ground microphones work through concrete, pavers, lawn and garden beds, so we do not need to dig to find the leak.
  • Drain camera inspections: When a drain or waste pipe could be the source, we put a camera down the pipe. The camera shows us the condition of the drain, where any crack or break is, and what caused it, such as tree roots. It also lets us rule out the drains when we are not yet sure where the water is coming from.
  • Pressure testing:When the location is still unclear, we isolate sections of the pipework and pressure test each one. A section that will not hold pressure is the section with the leak, and this narrows the search quickly.

The right combination of methods depends on what we’re looking for and where. In most cases we can locate the leak without opening a single wall or breaking any concrete.

Called out for an emergency at end of Oct and Rueben turn up at my property earlier than expected. Recount my problem to him and he patiently surveyed my driveway and while could not initially identified the source of the problem, he asked to survey my backyard as well. Sure enough the problem was there although the problem/symptoms were at the front of the house. Thank you for your time and delayed your dinner then to sort out my issues. Appreciate your professionalism and great work ethics.

I can’t recommend Reuben and Isaac highly enough! They recently came to my home to fix a complicated plumbing issue that had stumped several other plumbers. Not only did they diagnose the problems, but they also explained everything clearly. Their professionalism, skill, and attention to detail was very impressive. It was a relief to finally have the issues resolved. If you’re looking for plumbers who really know what they’re doing, these are your guys!

The boys did an absolutely fantastic job, with very little notice. They even corrected some work a previous plumber did. Fixed the pipes in my tiny kitchen reno, then came back and connected my appliances once the benchtop was done. Polite, friendly, they made me laugh. Would use them again. Can’t wait to use my kitchen once the electrician finishes the power points.

Rueben was a pleasure to deal with right from the start—nothing was ever a problem. He always kept me updated on what he was doing, and his team was very professional and clean. It’s so hard to find good, reliable tradespeople these days who don’t try to rip you off or do dodgy work. Blue Rhino Plumbing is very highly recommended—5 stars!

Pipe Leak Detection Under Slabs and Inside Walls

Leaks in the pipes that run under a concrete slab or inside a wall cavity can go unnoticed for weeks or months, because the water can soak into the ground or the framing for a long time before you see anything. A warm patch on a tiled floor can point to a leaking hot water pipe in the slab, and thermal imaging is one of the most useful tools for finding it. When we have located a pipe leak like this, we open only the small area needed to reach the damaged section of pipe, rather than lifting a whole floor or cutting along a wall.

What Happens After We Find the Leak

Once we have found the leak, we show you where it is and what has caused it, and we explain the repair options and the quote before any work starts. Many leaks come from a failed joint, a corroded length of pipe or a cracked fitting, and we can often repair those on the same visit.

When a drain pipe has cracked or has been damaged by tree roots, pipe relining can be the better repair, because it fixes the pipe from the inside without digging a trench. We offer pipe relining as a separate service, so ask us about it when you call.

Hidden Leak Allowance From Sydney Water

If a licensed plumber finds and repairs a hidden leak at your property, Sydney Water says you can apply for a hidden leak allowance on your water bill. Ask us for the details of the leak we found and the repair we carried out when you make your application.

Who Is Responsible for Fixing a Water Leak

Sydney Water explains that the property owner is responsible for the pipes and fittings on the property that connect to the water network, and that Sydney Water owns and maintains the water meter. If the leak is on the house side of the meter, a licensed plumber needs to find and repair it.

Pre-Purchase Leak and Plumbing Inspections in Sydney

A leak in a slab or behind a wall may not show up during a standard building inspection. If you are buying a property, we can inspect the internal pipework, the drains and the hot water connections before you sign, and give you a written report of what we found. If something needs attention, you will know about it before settlement rather than after you move in.

Leak Detection FAQS

Find answers to common questions about our plumbing services, pricing, and 24/7 availability across Sydney.

An unexplained increase in water usage almost always points to a leak somewhere in the system. The most common culprits are a running toilet (often silent, put a few drops of food colouring in the cistern and see if colour appears in the bowl without flushing), a dripping tap, or a hidden leak in the supply pipe between the meter and the house. If the obvious causes check out, call us for a detection inspection.

In most cases, yes. Our thermal imaging and acoustic equipment allows us to locate leaks with a high degree of accuracy before any surface is opened. When repair work does require access, we target the smallest possible opening, not a broad excavation.

For most homes, a thorough inspection takes two to three hours depending on the size of the property and the complexity of the plumbing. If we find something, we’ll discuss repair options before proceeding.

Turning off the mains is the right first step and it stops further damage. But the pipe still needs to be assessed and repaired before your water supply can be restored. Give us a call and we’ll get it sorted.

We will find where it is leaking from, it may need a new clamp, the pipe may need to be replaced or pipe relining can be a great solution for small cracks in a hard to reach pipe
