C Caroline Lowe Google review · Verified ★★★★★

After a leak was detected near my driveway, Kevin very carefully jack-hammered through and found the leaking pipe. He removed the pipe, replaced it with a new one, cemented over it and very neatly finished the surface. Kevin is an excellent plumber and problem solver — I would recommend him for any plumbing job.

Fire Service Leak Detection

Fire mains lose water quietly

Fire service mains sit on the bigger sites — schools, shopping centres, aged care, industrial estates, high rise. They feed the hydrant ring and the boosters, and they sit under pressure doing nothing at all until the day they are needed.

That is exactly why a leak on one goes unnoticed. There is no tap running, no fixture in use, nothing obvious to point at. It shows up as a pressure drop, a jacking pump cycling more than it should, a wet patch on the lawn that never dries out, or a water bill nobody can explain.

We locate leaks on fire service mains without shutting the site down and without digging up a car park to find out where the pipe runs.

Fire Service Leak Detection on the Sunshine Coast

What's involved

What we cover on these jobs

Underground PE mains

Most modern fire service mains are run in poly underground. We trace the line, then pinpoint the leak on it before anything is opened up.

Victaulic above ground

Grooved and Victaulic pipework through pump rooms and risers. Joints, gaskets and couplings are common failure points.

Older copper services

Plenty of older premises still run copper fire services. Age, ground movement and electrolysis all take their toll.

Pump rooms and boosters

Booster assemblies, jacking pumps and electric jockey pumps. A pump that keeps cycling is usually telling you something.

High-pressure nitrogen

For small leaks we charge the main with nitrogen from cylinder packs, then track exactly where it surfaces.

Trailer compressors

Larger mains need volume. We bring in trailer-mounted compressors to hold pressure on the system while we work the line.

Testing a fire main properly

Fire services are not domestic plumbing. The pipe is bigger, the pressures are higher, and the volume of air or gas needed to test one properly is well beyond what a small rig will deliver.

For larger mains we bring in a trailer-mounted compressor so we can hold pressure on the system long enough to work the line and find the loss. For smaller leaks, and where we need finer detection, we use cylinder packs of nitrogen at high pressure — it gives us a much cleaner signal to trace than air does.

Everything is done with the site in mind. Fire services are safety infrastructure, so isolation and reinstatement get planned with whoever manages the building, and we work in with your fire maintenance contractor where one is involved.

Common questions

Fire Service Leak Detection questions

Does the fire service need to be shut down to test it?
In most cases yes. To pressure test a fire main properly the system has to be isolated and shut down, so it needs to be planned rather than done on the spot. That usually means agreeing a window with the site or building manager, notifying whoever monitors the alarm, arranging an impairment or fire watch if one is required, and working in with your fire maintenance contractor. We often do it outside operating hours to keep disruption down. Once the testing is finished the system is put straight back into service.
What are the signs of a leak on a fire service main?
A jacking or jockey pump cycling more often than it used to, pressure that will not hold on the gauge, unexplained water use on the meter, or a soft or green patch of ground along the line of the main. Often the water bill is what prompts the call.
Do you work on schools and commercial sites?
Yes — that is where most fire service work is. Schools, aged care, retail, industrial estates and high rise. We are QBCC licensed and can work in with site inductions and access requirements.
What sort of pipe do you find leaks in?
Underground fire mains are usually poly, with Victaulic or grooved pipework above ground through pump rooms and risers. Some older premises still run copper fire services. We work across all of them.
Do you repair the leak as well?
We locate the leak and can carry out the repair where it falls within our licensing. On some fire services the repair needs a fire-accredited contractor, and we will tell you plainly which situation you are in. Call us on 0457 048 969 and we can talk it through.
