A Leak But No Water

[Veggie Dave]

Okay, what am I missing?

I have a customer with a water bill that's far higher than it should be given there are only two people in the house.
The water meter keeps turning, albeit very, very slowly, when nothing and no-one is using water.
If I isolate the customer side of the meter using the stopcock immediately after the meter the dials stop moving.
If I isolate all the brass ware and machines on the system the water dial still moves.
There isn't a single, solitary sign of a leak anywhere.

The vast majority of the system is visible, there's only a vertical run of around three feet that's boxed-in, but there's no sign of water at the bottom of this boxing.

I would swear blind there's no leak anywhere in the system, yet those meter dials keep moving. Theoretically there must be a leak but there isn't a single drop of water anywhere. :banghead:

its normally going to be a wc or other fixture. isolate one at a time and see what happens. ive had it where there was a hair line crack at the bottom of a cistern causing it to pass slightly.

funnily enough everytime i use the toilet i find a hair line crack!

Hair lined cracks are quite rare these days

Hi, as you have said the meter stops spinning when the isolator after the meter is turned off. This means the leak is between the meter and the isolator underground

I have had two of these, one was in a stud wall over concrete and the water was being soaked up in the concrete, the other was a burst heatex on the heat only boiler so the f and e kept dripping water in.
