Leak Detection Plumber in Adelaide

Leak Detection Adelaide |
Find Hidden Water Leaks Without Digging

A hidden water leak does not announce itself. It shows up as a water bill that does not make sense, a patch of carpet that never quite dries, or a faint sound of running water when every tap in the house is off.

We provide leak detection services across Adelaide using non-invasive equipment that locates the leak before anything gets cut open or dug up. We find leaks under concrete slabs, behind wall cavities, beneath floors, under driveways and along underground supply lines.

Blocked Drains in Adelaide?

We Find the Cause, Not Just the Blockage

Most blocked drains in Adelaide can be cleared in under an hour. The question that matters is whether it will block again in three months. Every job we attend includes a camera check of the line where the cause is not obvious from the fixture, so you find out whether you had a one-off blockage or a pipe problem that will keep coming back.

How We Find Leaks Without Digging

Locating a leak accurately is the difference between one small repair and a week of exploratory demolition. We use several methods together, because no single method works on every leak or every material.

Acoustic leak detection

Pressurised water escaping a pipe makes a sound at a frequency the human ear cannot pick up. Ground microphones and correlators detect that sound through concrete, tile and soil, then triangulate the position along the pipe run. This is the primary method for slab leaks and underground mains.

Thermal imaging

Water changes the surface temperature of whatever it touches. A thermal camera shows that temperature difference through flooring and plasterboard, which makes it fast for finding hot water leaks under slabs and tracing where water has spread inside a wall cavity.

Backflow Testing & Maintenance Process

Pressure and static testing

We isolate sections of the plumbing and pressure test each one in turn. This does not give a pinpoint location on its own, but it narrows the search to one line quickly and confirms whether the leak is on the supply side or the waste side.

Moisture mapping

Moisture meters and probes read the water content of building materials. Used across a floor or wall, they map the wet area and show which direction the water is travelling from.

Tracer gas

For leaks that will not show up any other way, an inert gas is introduced into the drained line. It escapes at the leak point and is picked up at the surface by a detector. This is the method for small leaks, empty lines and awkward materials.

Hidden Leaks

Where Hidden Leaks Usually Are

Under a concrete slab

Slab leaks are the hardest to spot and the most expensive to ignore. Warm flooring, a hot water system cycling more than it should, and hairline cracks appearing in tiles are the usual signs. We locate these acoustically so the repair can be a targeted cut rather than a lifted floor.

Behind a wall

Shower recesses, kitchen and laundry walls and bathroom plumbing chases. Water tracks down inside the cavity and often first appears in the next room or on the ceiling below.

Underground between the meter and the house

The supply line from the meter is the property owner’s responsibility, and a leak on it runs continuously onto the bill. Soft ground, one patch of grass greener than the rest, or water tracking along a driveway edge are the signs.

Under a driveway, path or paving

Locating accurately matters most here, because the alternative to a pinpoint is breaking up concrete and guessing.

Roofs, balconies and upper floors

Water appearing on a ceiling with no bathroom above it can be roof plumbing, a balcony membrane, or condensation rather than a burst pipe. We identify which before anything is opened up.

In the yard or garden

A wet patch that never dries out, especially through an Adelaide summer, generally means an irrigation line or the underground mains.

What Leak Detection Costs in Adelaide?

a plumber answering to a call if is a blocked drain an emergency

Leak detection is quoted separately from the repair, because until the leak is located nobody can price the fix honestly. What the detection costs depends on how much of the property has to be covered and which methods the leak requires. A single suspected line under a bathroom floor is a different job from tracing an underground main across a block.

What you can expect from us:

  • An upfront price for the detection before we start, not an hourly rate that runs on
  • The exact location marked, with photographs
  • A written report you can keep, send to an insurer, or give to another trade
  • A separate quote for the repair, which you are free to accept or decline

The reason detection is worth paying for separately is straightforward. An accurate location turns a repair into one targeted access point.

How We Work

Our Leak Detection Process in Adelaide

Book and describe the symptoms

Tell us what you are seeing and when it started. It helps us bring the right equipment and often narrows the search before we arrive.

Site assessment and isolation

We check the meter, isolate sections of the plumbing and establish whether the leak is on the supply side, the waste side, or outside the house entirely.

Non-invasive location

Acoustic, thermal and moisture equipment narrows the position down to a specific point. Nothing is cut or excavated at this stage.

Report, mark-up and quote

We mark the location, photograph it, write up the report and quote the repair. You decide what happens next, and you keep the report either way.

What We Cover

Why Adelaide Homeowners Call Wills for Leak Detection

Licensed and insured

South Australian licensed plumbers, licence number PGE 249 694. All work meets AS/NZS 3500.

We own our detection equipment

It travels on the van, which means we locate on the first visit rather than booking a second one once gear has been hired in.

10+ years working on Adelaide plumbing

Slab-on-ground construction across the newer suburbs, older galvanised and copper runs through the established inner suburbs, and reactive clay soils that move and stress underground lines. Where leaks occur here is not the same as anywhere else.

We find it before we open anything up

No exploratory cutting, no excavation on a hunch. The location comes first and the access point follows it.

Will came to my house to look at the roof stormwater drainage to the street. I only recently moved into this second-hand home and they had all sorts of DIY-looking downpipes, some of which went nowhere. He thoroughly investigated the issue, reassured me and came up with a good plan to fix it in a cost effective manner. On top of being professional he was also very personable and I had full confidence in his advice.

Fantastic experience. William was prompt friendly and polite. He got down to business straight away and didn’t waste time. He laid it all out and provided his honest opinion. He has the experience we needed to do the job and also showed us the inside of our pipes with the camera.

Thank you for the service and excellent help. Came out for our emergency blockage and checked out the house. Diagnosed the fault and supported us with SA water to resolve the issue.

I contacted Will late on a Sunday afternoon with blocked drains and not only did he respond quickly, but he made time to come first thing Monday morning. Will was professional and lovely to deal with. He went above and beyond contacting SA Water on our behalf, and followed up with me throughout the day to see how the job was progressing. As it turned out, the issue was on SA Water's side, but without Will's expertise and help I would never have known and possibly spent a lot of money paying for work that I wasn't liable for. I would highly recommend Wills Plumbing Adelaide.

William was excellent in his communication before, during and after his visit. He was clear with his explanation of our water hammer and pressure issues and transparent with his recommendations for remedies and cost. He was also friendly and understanding as I managed small children and our dog while he worked. Our water hammer issue appears to be fixed - he has asked us to keep him posted if we experience any further issues. Ongoing care - tick! We really felt well looked after and couldn’t recommend William highly enough. Thanks!

Will was a pleasure to work with. His communication was clear and responsive from start to finish. He went the extra mile by offering practical DIY ideas that could save us money, rather than immediately opting for a call out. Overall, Will's approachable attitude and willingness to help made a great impression. We’ll definitely reach out to him first for any future plumbing needs.
FAQ

We use a combination of acoustic detection, thermal imaging and moisture mapping. Pressurised water escaping a pipe makes a sound at a frequency you cannot hear, and ground microphones pick it up through concrete and tile. Thermal cameras show the temperature change water creates as it spreads behind plaster or under flooring. Together they narrow the leak down to a specific point, so when something does get opened up it is one targeted access point rather than exploratory demolition.

It depends on how much of the property has to be covered and which methods the leak requires. Tracing one line under a bathroom floor is a smaller job than following an underground main across a block. We give you a price for the detection before we start rather than running an hourly rate, and the repair is quoted separately once we know what we are dealing with. Call 0484 600 095 and describe the symptoms for an upfront price.

Yes, and slab leaks are one of the most common jobs we attend. They usually show up as a warm patch on the floor, a hot water system running more than it should, or hairline cracking in tiles. We locate them acoustically from the surface, which means the repair becomes a small targeted cut instead of lifting the floor to look.

Most residential jobs are located within one to two hours on site. Underground lines across a larger block, or leaks that need tracer gas because nothing else has picked them up, can take longer. We will tell you what we expect before we start and let you know if it turns out to be more involved.

That depends on your policy, and the distinction most insurers make is between a sudden escape of water and damage that built up gradually. What is consistent is that they will want a report from a licensed plumber before assessing the claim. Our detection report covers the location, the cause where it can be established, dated photographs and an assessment of how long the leak has likely been running. Tell us when you book if it is going to an insurer, so we can make sure the report includes what they need.

SA Water operates a concession for bills inflated by a genuinely concealed leak that was repaired promptly once discovered. Eligibility and any relief are decided by SA Water and the rules change, so check the current terms with them directly. What they generally want is evidence the leak was hidden rather than visible and ignored, evidence of when it was found and fixed, and a plumber’s documentation of the work. Our report and repair invoice cover that last part.

Yes. Detection and repair are quoted separately, so you see the cost of the fix before committing to it, but both are done by the same licensed plumbers. If you would rather take the report to someone else, that is fine, and you still keep it.

The supply line between the meter and the house is the property owner’s responsibility, and a leak on it runs continuously onto your bill. We locate these acoustically along the pipe run, mark the position, and repair with the smallest excavation the job allows rather than trenching the whole line.
