HOW DO WE FIND A WATER LEAK THAT YOU CAN’T SEE?
Not every water leak announces itself with a puddle.
Some leaks are hidden underground, beneath concrete slabs, inside walls, under floors or even within your swimming pool plumbing. By the time you notice damp patches, mould, cracks or an unusually high water bill, the leak may already have been causing damage for some time.
That’s where professional water leak detection comes in.
At Source Leak Detection, we use a combination of advanced, non-invasive technology and proven detection methods to locate leaks as accurately as possible, without unnecessarily digging up your property.
OUR LEAK DETECTION METHODS
Acoustic Leak Detection
Specialised listening equipment helps us identify the sound of escaping water within pipes, allowing us to narrow down the location of a hidden leak.
Tracer Gas Detection
A non-toxic mixture of hydrogen and nitrogen is introduced into the plumbing system. Where there is a leak, the gas escapes and can be detected with specialised equipment.
Pressure Testing
We test the pressure within the system to identify pressure loss or inconsistencies that could indicate a hidden leak.
Infrared Thermal Imaging
Thermal imaging detects temperature differences in walls, floors and ceilings. This can help identify hidden moisture and leaks, particularly in hot-water systems.
Moisture Meter Analysis
Moisture meters allow us to identify areas of excess moisture and help trace water accumulation that may not be visible to the naked eye.
The result? A more accurate diagnosis, less unnecessary damage and a clearer idea of where the problem is.
And we don't stop at simply finding the leak. Source Leak Detection can also assist with the necessary plumbing repairs.
Every leak detection service includes a detailed report with findings and photographic evidence, which can assist with insurance and water-loss claims.
THINK YOU MAY HAVE A HIDDEN LEAK?
Look out for:
• An unexplained increase in your water bill
• A water meter that keeps running when no water is being used
• The sound of running water
• Damp or warm spots on walls or floors
• Mould or musty smells
• Cracks or damage to walls and flooring
Don't wait for a small leak to become a major repair.
