Re: is anyone else having issues
I think this has bene posted in the wrong section? Mods?
As for your issue, unlikely to be deliberate, if its an infrequent fault then it could be a nice issue on the tap bank your connected to in either the chamber or cabinet outside your home. An engineer visit should still spot these issues and be able to resolve it.
The 6pm cut off seems to suggest that its some sort of local issue with noise/capacity.
