Leak detection in East Hampshire.

South East Water supplies East Hampshire at 280 to 310 ppm CaCO3 – hardness levels that gradually fur the interior of copper supply lines and create pin-hole stress points, particularly at pipe bends and solder joints. In properties around Selborne that draw on private water supplies, the chemistry varies further and can accelerate corrosion in ways a mains customer would not expect.

The leak picture in GU30 to GU36 is complicated by the same rural depth that makes the district distinctive: supply runs here are often longer, buried deeper, and less mapped than in a suburban setting. We locate hidden losses using three complementary methods. Thermal imaging reveals temperature differentials at slab and wall level, narrowing the search zone before any floor is lifted. Acoustic correlation listens to the pipe network under pressure, triangulating the precise leak point from the noise signature. Where the leak is deep or the background noise too high, tracer gas – a harmless hydrogen-nitrogen mix – permeates the pipe and rises to the surface at the fracture.

Every investigation closes with an insurance-grade written report: photographs, floor-plan markings, pressure readings, and a clear statement of cause. There is no callout fee; see /pricing for how the fixed project price is agreed.
