Leak under a garage built across the supply pipe
The property
A chalet bungalow on the slope of the ridge, with a detached garage added later across the line of the supply pipe from the road.
The problem
A damp tide mark crept along the bottom of one garage wall, and the bill had jumped. A plumber had checked everything indoors and found nothing.
How we found it
Closing the stop tap in the utility room left the meter creeping, so the leak was outside. Listening across the garage floor peaked by the side wall, and tracer gas agreed.
The outcome
We marked the spot on the concrete and photographed it. One opening in the garage floor reached the split, and the repair was priced before any work began.
