Where new pipe meets old under a front garden
The property
A house rebuilt on an original plot. New plastic pipe leaves the meter, then joins older metal pipe kept from the first home.
The problem
Essex and Suffolk Water's letter spoke of continuous use. The lawn looked normal, nobody knew where the join lay, and someone had suggested a trench.
How we found it
Even with the stop tap shut the dials kept moving. Tracer gas fed in at the house surfaced halfway down the lawn, where the ground microphone also peaked.
The outcome
Digging at the mark exposed the join between the two pipes. Only that patch of lawn was lifted, with the repair quoted separately first.
