LEAK DETECTION
Non-Invasive Leak Detection — Central Coast & Newcastle
A leaking pipe inside a wall or under a slab can go unnoticed for months, quietly rotting timbers, lifting tiles and driving your water bill through the roof. Robinson’s Coastal Plumbing uses acoustic listening sticks, thermal imaging cameras and tracer-gas detection to find the exact leak location — without jackhammering half the house.
- Acoustic correlation & listening sticks
- Thermal imaging cameras
- Tracer gas (hydrogen/nitrogen blend)
- Pressure testing & step-isolation
- Report + repair in one visit
- Insurance-compliant reports available
Signs You Have a Hidden Leak
💸 Unexplained High Water Bill
A sudden spike often means a concealed leak running 24/7.
🎵 Sound of Running Water
Hearing water when taps are all off is a classic pressurised leak.
🟤 Damp or Discoloured Walls
Stains, peeling paint or musty smells — especially on internal walls.
🪴 Soggy Patches in the Yard
Always-wet garden areas can be a mains or irrigation leak.
🌀 Water Meter Spinning
Turn everything off — if the meter moves, water is escaping somewhere.
🔥 Warm Spots on the Floor
In slab homes, warm patches often indicate a hot-water line leak.
