Landing stain from a pipe under the loft insulation
The property
A family home on a later estate, with a cold water tank in the loft feeding the bathroom, and its pipes buried under thick insulation.
The problem
Both owners were out at work all day and found a grey mark on the landing ceiling one evening. A letter about constant use followed.
How we found it
With every tap off, the dial still moved. Moisture readings followed the mark along the pipe that fills the tank; it would not hold pressure, and a thermal scan showed a cold line to one joint.
The outcome
Insulation was lifted only at the mark to reach the split joint, which we photographed. We mended it while there, on a separate quote.
