What Are the Signs of a Hidden Plumbing Leak?
Common signs include damp walls or ceilings, peeling paint, mould, unexplained water use, reduced pressure, warm patches, wet flooring and water sounds when fixtures are not being used.
Common hidden-leak signs
Where Might the Leak Be?
The visible warning signs, affected surface and water-pressure changes can help the provider understand which part of the plumbing system may need assessment.
Unexplained Water Usage
A sudden or gradual increase in water use without a clear change in household activity may indicate a hidden plumbing leak.
- Higher water use than normal
- Meter movement when fixtures are off
- No visible source of water loss
Wet Flooring or Warm Patches
Moisture, swelling, loose flooring or an unusually warm patch may point to a concealed pipe problem below the floor.
- Floor feels damp
- Tiles or boards lift
- Warm area without an obvious source
Water Sounds Behind Surfaces
Running, dripping or hissing sounds behind walls, ceilings or floors when no fixtures are in use may indicate hidden water movement.
- Dripping behind a wall
- Hissing near pipe routes
- Water sound with taps closed
Reduced Water Pressure
A sudden drop in pressure may relate to a supply problem, restriction or a significant leak somewhere in the water line.
- Weak flow from several taps
- Pressure changed suddenly
- Pressure varies unexpectedly
Commercial or Shared-Property Leak
Hidden leaks in offices, complexes, estates or managed properties may affect shared areas, tenants and water consumption.
- Shared water use increases
- Common areas become damp
- Several units report pressure changes
When not to wait
Signs the Leak May Need Prompt Attention
Some hidden leaks are more urgent because they are causing active damage, affecting electrical areas or spreading through ceilings and walls.
The damp area is spreading quickly
A rapidly growing wet patch may indicate active water movement behind the surface.
The ceiling is bulging or saturated
Keep clear of a badly water-damaged ceiling and avoid standing directly beneath it.
Water is near electrical fittings
Do not touch wet electrical equipment. Call for help and keep people away from the affected area.

Leak detection questions
Frequently Asked Questions
Clear answers about warning signs, urgency, water usage and what to provide before the callback.
What are the common signs of a hidden plumbing leak?
Common signs include damp walls or ceilings, peeling paint, mould, unexplained water use, reduced pressure, warm patches, wet flooring and water sounds when fixtures are not being used.
When does a hidden leak become urgent?
A hidden leak may be urgent when water is spreading quickly, the ceiling is becoming saturated, electrical fittings are nearby or the leak is causing active property damage.
Can a high water bill indicate a leak?
Yes. An unexplained increase in water use may indicate a hidden leak, although other causes should also be considered.
Should I switch off the water supply?
If it is safe and practical to do so, isolating the relevant water supply may reduce further damage. Do not access unsafe ceiling areas or wet electrical equipment.
