Supply pipe under a garage floor
The property
A 1970s link-detached house on a road out of Aylsham. From a pavement meter, the supply passes beneath the integral garage's concrete floor to the kitchen.
The problem
A constant-use letter came from Anglian Water. Toilets and taps all checked out, the meter still turned overnight, and nothing looked wet anywhere.
How we found it
Closing the kitchen stop tap made no difference to the dial, so the buried pipe was leaking. On the garage floor the ground microphone peaked halfway along; tracer gas rose through a crack there.
The outcome
With the car moved, one small square of concrete came out. We mended the joint, priced on its own, and the owner used our report to ask Anglian Water about an allowance.
