Farm supply leaking at a forgotten trough pipe
The property
A farmhouse outside the town, its meter at the lane and its supply crossing a yard and a sloping paddock by an unknown route.
The problem
The bill had crept up, the meter turned with every tap shut, and a wet hollow had formed at the foot of the paddock.
How we found it
The stop tap test put the loss outside. Walking the line, the ground microphone led us well uphill of the hollow, to an old trough branch where tracer gas surfaced.
The outcome
The perished joint was marked and photographed. The owner had the unused branch cut off and capped, quoted separately, and the report records the route.
