Leak Detection in Kirra

The first move on any suspected leak in a beachside home is the water meter, and it is the one check you can do before we arrive. Everything off, note the reading including the small red digits, wait 30 minutes to 2 hours, read it again. If it has moved, water is escaping past the meter. What that test cannot tell you is where, and on the coast the where is the hard part.

Why coastal leaks hide better than inland ones:

• Sandy soil disperses water instead of pooling it. On a clay block a buried leak eventually surfaces above the break. On the sand profiles behind the beach strips it drains down and sideways, so you get either no surface evidence at all or a soggy patch well away from the pipe that is leaking. Chasing the wet patch on a coastal block is how people end up digging three holes and finding nothing.
• Salt-driven pinholes are small. Chloride pitting works through copper from the outside in, so the hole that finally opens is often a fraction of a millimetre. It hisses rather than gushes, which is good news for acoustic detection and bad news for anyone hoping to spot it by eye.
• The pipe runs are not where the plan says. Most of the original beach cottages have been extended and part-repiped across 40 or 50 years, by more than one plumber and rarely with drawings. We locate the line before we listen to it, otherwise we are listening to the wrong ground.

How we work a coastal leak. Confirm it at the meter, then close the isolation valve where the supply enters the house and re-read. Still moving means the leak sits in the service line between the meter and the house, which on the older beach strips is one of the most common finds. Stopped means it is in the house pipework, so we isolate hot from cold and pressure test each side separately. Once we know which line owns it, we trace the route with a pipe locator and pinpoint with acoustic ground microphones. Thermal imaging comes out for hot water lines, where the warm plume shortlists the zone before the microphone confirms it. Nothing gets opened until there is a mark on the ground or the floor.

Where we actually find them. External and under-house runs are over-represented, because that is where salt-laden air reaches copper most easily. Hose bib supply lines, the run out to an outdoor shower, the section that ducks under a raised timber floor, the buried service line under a driveway. In-slab failures still happen and we test for them, but on the coast we work the exposed runs early because that is where the odds sit.

Then we fix it. We are a QBCC licensed plumbing business (licence 15243081), so you are not paying us to hand over a report and drive off. On an accessible break the repair usually happens the same visit. The harder conversation is the second or third pinhole in the same 40 year old copper. At that point a spot repair is buying months, and rerouting the run or repiping it in PEX is the honest recommendation. We put both options in front of you with prices rather than steering you to the bigger one.

Non-invasive leak detection on the Gold Coast runs $200 to $500 or more, and where a coastal job lands in that range comes down to how much ground we have to cover. A leak confirmed at the meter and pinpointed on a short service line sits near the bottom. A sandy block with no useful surface evidence, undocumented pipe routes and long external runs takes the full toolkit and sits at the top. Pool leak detection is its own scope at $300 to $600 or more.

The detection fee buys you the location. The repair is quoted separately as a fixed price in writing once we know what we are dealing with, typically $250 to $650 plus parts for an accessible break and $1,500 to $4,000 or more where we have to go through a slab. If water is running now and it genuinely cannot wait for business hours, after-hours attendance carries a higher rate plus the work, and we tell you that rate on the phone before we leave.
