Launderette bill climbing with the machines idle
The property
A town centre launderette with a row of washers along one wall. Their cold feed runs in a channel under the floor from a stop tap by the door.
The problem
The water bill kept rising though trade was steady. Nothing pooled on the floor, and none of the machines showed a drip.
How we found it
With the machines off and the stop tap shut, the dial went still: the loss was inside. A pressure test showed the washer feed failing, the ground microphone peaked halfway along, and moisture readings there agreed.
The outcome
Marked and photographed, the spot meant opening only the floor above it. As a business, the launderette paid before the visit, and the repair was quoted separately.
