Signs You Have a Hidden Leak

Water leaks aren’t always obvious. Here are the warning signs to look out for:

  • Unexplained increase in your water bill
  • Damp or wet patches on walls, ceilings or floors
  • Mould or mildew appearing without an obvious cause
  • Sound of running water when all taps are turned off
  • Warm or hot spots on floors (slab leak)
  • Cracked or lifting tiles
  • Low water pressure throughout the home
  • Meter continues to move when all water is turned off
  • Musty smell in rooms with no visible moisture source

If you notice any of these signs call Aqua Blast on 0414 706 029 for same-day leak detection across Sydney.

How We Fix It

1. Visual Inspection

We start with a thorough visual inspection of all accessible pipes, fittings and fixtures to identify any obvious signs of leaking.

2. Water Meter Test

We perform a simple water meter test to confirm a leak is present and estimate the flow rate of the leak before using specialist equipment.

3. Non-Invasive Leak Detection

Using thermal imaging, acoustic listening devices and moisture meters we pinpoint the exact location of the leak without opening walls or digging up floors.

4. Clear Report and Quote

We show you exactly where the leak is and provide a clear upfront quote for the repair before any work begins. No surprises.

5. Leak Repair

Our licensed plumbers repair the leak using the most appropriate method, whether that’s pipe repair, pipe relining, joint replacement or a full section replacement.

6. Final Check

We perform a final pressure test and water meter check to confirm the leak is completely resolved before we leave your property.

What Causes Hidden Leaks

Understanding what’s causing your blocked drain helps us fix it permanently, not just temporarily. The most common causes we see across Sydney properties include:

Corroded or Ageing Pipes

Older properties across South West Sydney and Greater Sydney often have copper or galvanised steel pipes that corrode over time. Small pinholes develop and can leak for months before being noticed.

High Water Pressure

Excessively high water pressure puts stress on pipes, joints and fittings. Over time this causes small leaks to develop at the weakest points in your plumbing system.

Tree Root Intrusion

Tree roots are attracted to moisture and can penetrate underground pipes causing cracks and leaks. Common in established Sydney suburbs with large trees.

Poor Workmanship

Leaks can develop at poorly fitted joints, connections or fittings, particularly after renovation work. These leaks often start small and get progressively worse over time.

Ground Movement

Sydney’s clay soils expand and contract with moisture levels. This ground movement can shift underground pipes causing cracks, joint failures and leaks beneath your slab.

Frequently Asked Questions

How do I know if I have a hidden water leak?

The most reliable way to check is the water meter test. Turn off all water in your home, then check if your water meter is still moving. If it is, you have a leak. You can also check your water bills, an unexplained increase is a strong indicator.

No, we use non-invasive leak detection technology including thermal imaging and acoustic devices to pinpoint the leak location without breaking through walls or floors. We only open up the minimum area required to make the repair.

Most leak detection inspections take 1–2 hours. Simple leaks can often be repaired the same day. Complex slab or underground leaks may require a follow-up visit depending on the repair method required.

Yes, even a small pinhole leak can release hundreds of litres of water per day into your walls or subfloor. Over time this causes timber rot, mould, concrete corrosion and significant structural damage. Early detection saves thousands in repair costs.

Call us for a leak detection inspection. Many leaks are completely invisible from the surface, inside walls, under slabs or underground. Our non-invasive technology finds them without any guesswork.
