Plastic pipe leaking under a newer home's floor
The property
A newer semi on the edge of town, with plastic push-fit pipework, a solid insulated ground floor and the stop tap in a kitchen cupboard.
The problem
Anglian Water wrote about water passing at all hours. The owners had checked every tap, toilet and appliance, and found no damp or warm spot anywhere.
How we found it
With the kitchen stop tap closed the dial stood still, placing the leak indoors. A pressure test showed the cold pipe under the ground floor losing water, and tracer gas came through the hall screed at the split.
The outcome
The point was marked and photographed. The owners took the repair quote on the day, so we opened a small patch of floor and replaced the failed fitting.
