Methods Used at Pro Leak Detection

At Pro Leak Detection, we use the latest advanced technology to deliver accurate, non-invasive UK leak detection services. Using our cutting edge technology we minimise any unnecessary damage to your property. Once the leak has been located we provide you with an indepth photographic report highlighting the root cause of the leak and the damage caused. This report can be submitted to your insurance provider if required.

Boiler Service & Repairs

Our gas tracing method involves the use of a specialized tracer gas, an inert blend of 5% hydrogen and 95% nitrogen, which replaces water in the leaking pipework. When pressurized, this gas escapes from the leak and ascends through the floor, ground, or walls. The gas can permeate various materials, including concrete floors, timber, and different floor finishes such as tiles, laminate, and carpet. A highly sensitive probe precisely identifies the leak by detecting even minute traces of the gas, down to just a few parts per million. Gas tracing is applicable to all types of pipe leaks, including central heating, underfloor heating, mains, hot, and cold, providing a highly accurate means of locating leaks. Pro Leak Detection use the latest gas leak detection techniques ensuring that we can locate and resolve hidden leaks with minimal disruption to you and your home.

Acoustic Detection

The Acoustic Microphone is an exceptionally sensitive device designed to detect the sound of a leak escaping from a pipe. This device can effectively magnify the noise, especially when the system is drained down, and water is replaced with air, creating a distinctive and recognizable sound. Initially, it confirms the presence of a leak and provides an approximate location. Further refinement, such as calibrating the sound from two different positions, allows for precise pinpointing of the leak’s exact location. The Acoustic Microphone is versatile and applicable to various types of pipe leaks, including central heating, underfloor heating, mains, hot, and cold. We take pride in employing the latest leak detection techniques, ensuring we locate and resolve issues with the least amount of disruption to your property.

Thermal Imaging

The Thermal Imaging Camera, also known as a Thermographic or Infrared Camera, enables us to identify and map buried and concealed hot, central heating, and underfloor heating pipes. By detecting infrared energy and converting it into an electronic signal, the camera produces a thermal image and performs temperature calculations. Abnormalities and suspect areas, such as heat patches are an indication of a leak. The thermal imaging results complement our other testing methods and equipment, contributing to the accurate location of the leak. Employing our latest leak detection techniques ensures that we can locate and resolve problems with minimal disruption to you and your property.
