Heating leak hidden under a bungalow's kitchen units
The property
A 1970s bungalow on one of the private estates, its radiator pipes buried in the concrete floor and partly hidden under fitted kitchen units.
The problem
Topping up every other day had become normal. The heating engineer had passed the boiler and even changed its safety valve, yet the gauge kept falling.
How we found it
Isolating sections left the kitchen run losing pressure. The units hid most of it from the thermal camera, which caught only warmth at the plinth, so tracer gas was fed in and rose there.
The outcome
Marked at the plinth and photographed, the leak was repaired while we were there, as quoted: one base unit eased out and a small patch of concrete opened.
