Central heating leak detection in Edinburgh
A dropped pressure gauge, a damp patch, or a boiler that keeps losing pressure. Finding the leak is usually the expensive part — not fixing it.
Why leaks are harder to find in Edinburgh than elsewhere
Tenement flats share walls, floors and risers with neighbours. Pipework runs under boards and through communal spaces, so a leak can surface in a completely different flat from the one it started in. Chasing the wrong floor is how repair bills escalate.
The engineer's job is to narrow the search before anything is opened up.
The usual suspects
Pressure loss with no visible water
A sealed system losing pressure is leaking somewhere — often under a floor or inside a wall where you will never see it.
Damp patches and staining
Usually a pipe joint or a radiator valve. Tell-tale brown staining on a ceiling or skirting points at the general area, not the exact joint.
Radiator valves and joints
The most common single cause, and the cheapest to fix once found.
Boiler components
Internal leaks from the heat exchanger, pump or pressure relief valve.
Corroded pipework
Older steel and iron pipework in Edinburgh's tenements, often hidden behind plaster.
Communal and shared risers
Needs coordination with neighbours and sometimes the factor. Slow, but avoidable if diagnosed properly first.
What to do while you wait
- Note the boiler pressure reading, and whether it falls when the heating is on or off — that narrows it down
- Photograph any damp patch and check it again in 24 hours to see if it is spreading
- If water is near electrics, isolate the supply at the consumer unit before anything else
- Do not keep topping up the pressure indefinitely — fresh water accelerates corrosion
- Tell the engineer which floors are below or above — in a tenement this matters
