One leak, three cottages on a shared supply
The property
A row of three old cottages near the centre, fed by one supply pipe that runs under the end cottage's front and branches to the others.
The problem
The water company wrote to the middle cottage. Nothing was wet in any of the three, and nobody knew whose part of the run leaked.
How we found it
With all three stop taps shut the meter still ran. The ground microphone peaked under the end cottage's path, and tracer gas agreed.
The outcome
The leak sat on the shared length before any branch. Using the report, the owners agreed the repair between them, which we quoted and made.
