Tall town house topping up every day
The property
An older town house in the centre, three floors high with radiators throughout. Heating pipes run beneath suspended timber floors and down inside the walls.
The problem
The boiler needed topping up daily, and a faint mark had appeared on the kitchen ceiling. Every radiator valve had already been checked.
How we found it
Closing circuits floor by floor left the first floor losing pressure. With the heating warm, the camera traced a hot pipe under the bathroom boards, and tracer gas confirmed it.
The outcome
A short length of floorboard came up at the mark, and the repair was quoted separately. The kitchen ceiling below was left to dry out before redecorating.
