Meter in the pavement, leak under the hall
The property
An older brick house near the middle of the village, with timber floors. Water comes in from a pavement meter and crosses beneath the hall to a kitchen stop tap.
The problem
A letter said water was passing through the night. Nothing was damp, the toilets were quiet, and the garden tap had been checked.
How we found it
With the stop tap at the back closed, the dial still crept round. On the boards, the ground microphone picked up the loudest hiss under the stairs, and tracer gas agreed.
The outcome
A pair of boards lifted at the mark showed the leak. We repaired it on a separate quote, and our report gave the owner something to show the water company.
