Thermal cameras see heat rather than visible light. They can be very sensitive to tiny changes in temperatures the ones that our Thermal Imaging leak detection specialists use can detect a difference of 0.05°C and can give us an instant picture of hot and cold spots in the building and this often shows us where hidden pipes run and where water is leaking from them as the temperature of the water in the pipes affects the temperature of nearby surfaces.
It’s all done with pictures! We can scan quite large areas at a time and from a distance looking for thermal anomalies signs that something is just not ‘quite right’ and then zero in for a closer look. There’s absolutely no need to disturb, or even touch, ceilings, walls or floors in order to find the leak source.
Sometimes an anomaly, or clue, can be seen in the images and sometimes the exact location of the leak can be determined accurately it often comes down to interpreting the thermal images correctly and this is something that our trace and access leak detection specialists are experts at doing.
Tracer gas is made up of a mix of hydrogen and nitrogen. Tracer gas is a harmless lighter-than-air gas. It can be injected into an empty pipe at modest pressure and will escape from the pipe from any leaking areas. It then rises straight to the surface going straight through any common building material, such as concrete, in the way. Once on the surface, our trace and access leak detection specialists can find the tracer gas using a sensitive gas detector.
Use of tracer gas is totally non-invasive – once it has left the pipe from the leak location, it goes straight up through almost all building materials including concrete, paving slabs, sand and soil and can be detected at the surface directly above the leak location. Water, of course, does not do this and tends to spread out both sideways and downwards making it much harder to find the precise leak location and necessitating much larger scale excavation works to find the actual leak.
Tracer gas can be used in pipes of all sorts of sizes and lengths and of all sorts of materials. It leaves no residues or deposits and can do no harm.
It’s a completely safe gas to use: non-toxic, non-corrosive, non-flammable and approved for use in drinking water pipes, waste pipes, central heating pipes, rising mains and petroleum pipelines. It poses no environmental risk and dissipates quickly.
Acoustic leak detection is one of the more traditional methods used in tracing a leak. Water escaping from a leak in a pipe, makes a noise. The greater the pressure of water in the pipe, the more it causes the pipe leak location and the surrounding material to vibrate and, generally, the louder the noise
Sensitive amplified microphones can be used to home in on the leak by listening at various points and looking for the area with the loudest noise this is where the leak will be found.
There is no need to dig up floors or drill holes or even disturb floor coverings; in fact, the denser the material is between the leaking pipe and the surface, the better vibration will travel and the louder the noise that can be picked up on the surface.
Sometimes pipes are buried quite deeply and other methods of detection are not very effective; an infra-red or thermal camera for example, will not be able to find any change of temperature on the surface caused by a pipe that is both well insulated and deeply buried especially if the water in the leaking pipe is cold or close to the temperature of the surrounding material. In this sort of case, trace and access leak detection specialists often rely on acoustic techniques.
The point on the surface where the noise is loudest is usually the closest point to the actual leak and this can enable us to pinpoint the exact location to dig down and expose the leak for subsequent repair.
There’s nothing like a direct picture of the leak in action; other forms of leak detection like thermal imagery, moisture readings and tracer gas work very well but they are indirect and don’t allow us to actually see the leak. Endoscopy, however, gives us a live picture showing exactly what’s going on.
The light at the end of the thin flexible tube enables our trace and access leak detection specialists to peer past obstacles and shine a light on the problem areas.
