How a Pressure Test Finds a Leak: Isolate, Pressurise, Watch the Gauge
Pressure testing closes off a length of pipework, fills it with water or air at a set pressure, and watches a gauge. If the needle holds, that pipework is not…

How leaks are located: methods explained
In short
No single method finds every leak, and a good survey combines them. These guides explain how tracer gas, acoustic detection, thermal imaging and pressure testing work, what each needs, and where each gives no answer, so you know what to expect before a survey.

MethodsHow Do You Find a Leak in a Pipe? The Order of Tests and What Triggers Each
A leak in a pipe is found by letting each test result choose the next move. A moving meter sends the search to the supply pipes, a still meter sends it…
MethodsHow Does Tracer Gas Leak Detection Work? Gas In, Detector Over the Surface
Tracer gas leak detection fills an isolated pipe or sealed circuit with a lean hydrogen and nitrogen mix. The gas escapes wherever the pipe is breached, rises…
MethodsHow Thermal Imaging Finds a Leak: Heat Flow, Colour and What It Cannot See
A thermal imager does not see water. It shows surface temperature, and a leak can change a surface temperature: a wet patch is usually cooler because…
MethodsNon-Invasive Leak Detection Methods Compared: What Each One Senses and Where It Stops
Five non-invasive methods find hidden leaks without opening the structure: pressure testing, acoustic listening, tracer gas, thermal imaging and moisture…
