You don't want to be using the hot tap in an unknown location for anything that goes in your mouth!
In UK so far as I understand it any kitchen cold tap must come directly from the mains water supply. this doesn't have to be the case for other cold taps in the house. never use water from a hot tap for anything but washing. Due to the problems mentioned right above. They're all true.
