Unexplained water usage overnight ...

[Chuck]

Along similar lines to @IND_Nick, one possibility that occurred to me was that there is a redundant connection, which should have been disconnected but was overlooked, from the property to another main. I've not come across myself but have heard 'war stories' told by others so it's an unlikely scenario but it could explain the rather strange pattern of behaviour.

If this were the case, the OPs water meter might be expected to under-read water consumption during the day so it might be interesting review the data from the water meter to see if it matches the actual consumption during the day.

I reckon the cat has learned to flush the loo and is absolutely loving setting his owner this conundrum.

Thanks @ShaunCorbs ... I've had the toilet checked by a plumber recently when I had some new radiators installed and there was no leak - also bought the dye tablets that you put in your cistern to check for any leaks overnight but there was nothing. I remain convinced that it's not a leak as I was away for 3 days with zero water usage being recorded at all during the day - just the same scenario that I've now had for 3 years where water is being "consumed between midnight and 8am. I'm baffled. Thanks for your advice as I'm sure the answer is out there somewhere.

Hi Sandra did you ever get this resolved? We have a similar issue
