Old metal supply pipe under a carrstone front path
The property
A Victorian carrstone terrace with a small walled front garden and a pavement meter, its old metal supply pipe buried beneath the path.
The problem
Anglian Water wrote that the meter never stopped. Toilets and the garden tap were ruled out, and a builder suggested digging up the whole path.
How we found it
The meter still ran with the indoor stop tap shut, putting the fault under the path. On old metal the hiss of a leak travels well, and the ground microphone picked it up halfway along; tracer gas confirmed it.
The outcome
Two flagstones came up and the corroded section was replaced, quoted separately. Because old pipe can fail again nearby, renewing the run was priced as an option.
