We have a water meter at our property and have recently noticed our consumption seems to be up. One of the dials on the meter is constantly slowly moving around even when no water has been in use for a while. We have no leaking taps etc and Homeserve have confirmed they can see no trace of leaks above floorboards. Our concern is that there could be a leak below the floorboards which will be hard to access. Is it normal for one of the dials on a water meter to be constantly moving?
