Leak Detection Sydney Find the Source Before You Start Breaking Things.
Suspect a hidden water leak? JNG Plumbing Group provides professional water leak investigation across Sydney using pressure testing, acoustic listening equipment, thermal imaging and targeted testing methods to help narrow down the source of concealed and underground leaks.
Could You Have a Hidden Water Leak?
Concealed water leaks can develop before the source becomes obvious. These are some common signs that may justify further investigation.
Unexplained Water
Water appearing from walls, floors, ceilings, cupboards or external areas without an obvious source.
Water Meter Movement
Your meter continues to register water use when fixtures throughout the property are turned off.
Higher Water Usage
An unexplained increase in water consumption may indicate water escaping somewhere within the plumbing system.
Damp Walls or Floors
Staining, moisture, bubbling paint or deteriorating finishes may be associated with concealed water movement.
Wet Ground
Persistently wet soil, pooling water or unusually green areas may indicate an underground water-service leak.
Pressure Changes
A noticeable change in water pressure can sometimes warrant further investigation of the pressurised water service.
How We Locate Hidden Water Leaks
There isn't one tool that finds every leak. Different methods provide different pieces of information, which can then be considered together to narrow down the source.
Pressure Testing
The water service can be isolated and pressure tested to help determine whether pressure is being lost within the tested plumbing system.
✓ Helps establish whether pressure loss is presentAcoustic Leak Detection
Specialist acoustic equipment may be used to listen for sounds created by pressurised water escaping from concealed pipework.
✓ Helps narrow down the likely leak locationThermal Imaging
Thermal imaging can assist by identifying temperature differences that may be associated with moisture or water movement.
✓ Useful supporting investigation toolTargeted Investigation
Test results, plumbing layout and site observations are considered together to help determine where further investigation or access should occur.
✓ Evidence before unnecessary demolitionListening for a Leak You Can't See
When pressurised water escapes from a damaged pipe, it can create vibration and sound that travels through the surrounding pipe, ground or building materials.
Acoustic listening equipment can be used in suitable situations to compare these sounds across an area and help narrow down the likely position of the leak.
The Wet Spot Isn't Necessarily the Leak Location
Water can move underneath flooring, along slabs, through wall cavities and across building materials before it eventually appears somewhere visible.
Leak Detection Equipment & Testing
The testing used depends on the type of leak, plumbing system and conditions found at the property.
Acoustic Equipment
Specialist listening equipment for investigating sounds associated with escaping pressurised water.
Thermal Camera
Used as a supporting tool to investigate temperature variations and suspected water movement.
Pressure Testing
Used to determine whether an isolated pressurised water service is maintaining pressure.
Dye Testing
Useful in suitable investigations involving waterproofing, fixtures and suspected water pathways.
From Leak Investigation to Repair
Once the investigation has provided enough information, we can explain what has been found and what the next step may involve.
Investigate
Inspect the property and gather information about where and when the water is appearing.
Test
Perform suitable tests such as pressure testing, acoustic investigation or thermal inspection.
Locate
Combine the findings to narrow down the likely source and determine where access may be required.
Repair
Where appropriate, JNG Plumbing Group can carry out or provide a quote for the required plumbing repair.

Frequently Asked Questions
Depending on the plumbing system and symptoms, we may use a combination of pressure testing, acoustic listening equipment, thermal imaging and targeted investigation to help narrow down the source.
Leak detection is intended to help narrow down the likely source before unnecessary invasive work is carried out. Physical access may still ultimately be required to expose and repair the pipe.
Pressure loss can indicate an issue within the tested water service, but the isolation points, testing conditions and plumbing system need to be considered before determining the cause.
Yes. Water can travel under floors, through cavities and along building materials before becoming visible, which is why the visible wet area may not be directly beside the failed pipe.
We can investigate suspected underground pressurised water leaks and use suitable testing methods to help narrow down the affected area.
Yes. Once the problem has been sufficiently identified and the required access is agreed upon, JNG Plumbing Group can carry out or provide a quote for the appropriate plumbing repair.
