The Sewerin and the RD8000 pipe locators are high radio frequency devices used by our water leak detectors in combination with other testing methods. The use of this advanced leak detection technology is essential to locate and trace the water pipes internally and externally prior to testing for water leaks.

The acoustic leak detection system uses electronic equipment to isolate the lowest noise emitted consistently by water escaping the pipework. Detecting underground water leaks is possible for plumbing leakage at a rate greater than 6 litres per minute. The acoustic method works by reducing interfering noise such as vehicular traffic, chatter or pedestrian footsteps during testing and focuses on isolating the sound of water escaping the hidden pipes.

Hydrogen tracer gas is a versatile and cutting edge water leak detection system used by leak location specialists. This advanced technology uses a safe mixture of Hydrogen and Nitrogen that is released into the pipework to detect a water leak.

Due to its light composition containing the smallest and lightest atoms, H5 can escape through the most minute pipe leak into the atmosphere. The dispersing H5 gas is then detected by the highly sensitive probes. The specialist Sewerin equipment is a precise and efficient leak detection solution.

Thermal imaging is used to scan building surfaces to detect heat, thermal variations or hotspots from leaking water pipes. The readings are indicative of the moisture content in building materials, a hotspot is a strong indicator of a pipe leak. This testing method provides the advantage of gaining valuable insight without cutting or causing damage when searching for a hidden plumbing water leak.

Water leak location with thermal imaging technology offers a reliable avenue to scan large surfaces fast in search of moisture. Entire ceilings, walls and floors can be effectively surveyed in search of moisture transfer or a water leak in tandem with other specialist leak detection equipment.
