Dry lawn over a split supply pipe
The property
A semi-detached house in a row of matching homes, its blue plastic supply crossing the front lawn from a meter in the pavement.
The problem
Anglian Water wrote about constant use. The grass stayed green and dry; only the meter, still moving with the stop tap shut, pointed outside.
How we found it
Loose sand muffled any hiss. The outside length failed a pressure test, so we pumped in tracer gas, which the detector picked up halfway across the lawn. Set on that spot, the microphone caught a faint hiss.
The outcome
Once the spot was marked and photographed, only the turf above it was lifted. We priced the repair on its own, and the report let the owner answer Anglian Water.
