Greener strip across a bungalow lawn at Henlow Camp
The property
A bungalow at Henlow Camp on a concrete floor, its supply pipe running from a meter by the pavement, under the front lawn, to the kitchen.
The problem
A water company letter arrived, and a strip of lawn had grown greener and softer than the rest. Nothing indoors was damp.
How we found it
The meter carried on with the stop tap closed, putting the leak outdoors. We walked the ground microphone along the green strip; it peaked near the path, and tracer gas agreed.
The outcome
A small hole at the mark exposed a split in the old pipe. A new length to the wall was quoted separately and fitted while we were there.
