Leak letter for a semi with a paved front
The property
A post-war semi whose front garden is paved for parking, with the meter at the pavement edge and an old supply pipe under the slabs.
The problem
The water company wrote about continuous use. A damp line had appeared between two slabs, and the owner could not tell pipe water from rain.
How we found it
Even with the stop tap off, the dial crept on, so the fault was outdoors. The ground microphone peaked beside the damp line, and tracer gas seeped up through that joint.
The outcome
Only two slabs were lifted for the repair, priced separately. Knowing old pipe can fail elsewhere, the owner also planned to renew the rest of it.
