Leak Detection & Prevention

Unseen leaks can cause serious damage and push your water bills up fast. A leak behind a wall, under the floor, or in the main supply line can grow without you noticing. Our leak detection and prevention service uses acoustic listening gear, thermal imaging, and pipe cameras to find the source accurately without ripping things apart. Once we locate the leak, we repair it and give clear advice to stop it from coming back. Sorting leaks early protects your property and your budget.

Our Leak Detection Process

Leak detection with MPJ starts with the clues you’ve noticed. Higher water bills, damp spots, reduced pressure, or the sound of water running.

We walk through the site with you, then use the right tools to pinpoint the leak. Acoustic detectors help us hear water in walls or underground, and thermal imaging highlights cold or damp areas. If the issue is in a drain line, we run a CCTV drain camera through the pipe to find cracks or breaks. If the pipe is cracked, we may recommend pipe relining technology instead of full replacement.

Once we know exactly where the leak is, we open only the small section needed, repair or replace the damaged pipe, and test the line to make sure it’s fixed. At the end, you get clear advice on how to stop the problem from coming back.

Why Choose Us: Preventing Future Leaks

Beyond just fixing the leak at hand, MPJ Plumbing Group helps you adopt measures to prevent future leaks in your Sydney property:

Regular Inspections

Small leaks often start quietly. A tiny drip behind a wall or a joint that’s just starting to corrode won’t show up right away, but over time it can lead to a burst or water damage. Regular inspections and maintenance help catch these early signs. We walk through your building, check common stress points, look at pipe joints, valves, and any older sections that might be weakening.

If something is beginning to fail, we can deal with it while it’s still minor. This kind of routine care is especially useful in older buildings or busy sites where the plumbing gets a lot of use. A quick inspection now is far cheaper than dealing with a soaked wall later.

Quality Installations

If a leak keeps happening in the same spot, it’s usually down to the original installation or the material used. Some older fittings just don’t hold up well long-term, especially with Sydney’s water pressure.

We can swap out those weak links and replace them with stronger, better quality pipes and fittings that last. It could be one section, a few metres of pipe, or a valve that isn’t sealing properly.

Once the weak part is gone, the whole system becomes more reliable. Doing it right once is always cheaper than calling a plumber every few months to patch the same problem.

Pressure Management

High water pressure feels great in the shower but it can batter pipes in the background. Joints, seals, and older copper or plastic sections can slowly get stressed until they crack or start leaking. We test your water pressure to see if it’s sitting at a safe level.

If it’s too high, we can install or adjust a pressure reducing valve. It’s a small change, but it can extend the life of your plumbing by years. Keeping the pressure steady helps prevent sudden leaks and reduces the chances of pipe bursts down the track.

Backflow Prevention

Backflow prevention devices stop water from flowing the wrong direction through your pipes. Without them, dirty or stagnant water could push back into the clean supply, which can cause contamination or unexpected leak pressure.

We check that your backflow devices are installed properly, working as they should, and certified. If one is worn out, we replace it. This protects your drinking water and helps keep your plumbing system in good shape. It’s one of those quiet protections that you don’t think about until it stops working so keeping it maintained matters.

Education and Tips

A lot of leaks get worse simply because no one spotted the signs early on. We take a moment to show your staff or tenants what to look for day-to-day: slight damp patches, small drips, changes in water pressure, or sounds that don’t make sense.

We also point out where the shut-off valves are, so water can be stopped quickly if needed. This small bit of knowledge can save you thousands in repairs and damage. Knowing how to react fast is just as important as the repair itself.
