Wet ground by the gate, leak further up the drive
The property
A detached Victorian house down a lane on the mid Suffolk clay. Its old supply runs about 80 metres from the roadside meter under a gravel drive.
The problem
A letter warned of constant use, and the ground by the gate had stayed boggy for weeks. The owners dug there twice and found the pipe dry.
How we found it
After questions about length and route, a pressure test showed the outside length leaking. The ground microphone peaked well up the drive, and tracer gas rose through the gravel beside it.
The outcome
Water had followed the old trench down to the gate. One hole at our mark found the split. Old pipe can fail elsewhere too, so we explained that any further leak would be quoted separately.
