Re: Tap water in the uk
It was only when I returned to the UK after many years absence that I discovered how undrinkable the water was.
A lot of places seem to have hard water and it tastes foul (not necessarily because it is hard) I remember my parents trying all sorts of tricks to stop the kettle furring up. Soap never seemed to lather up.
I really can only speak for water from Kent and Gloucestershire I vaguely remember Glasgow water was OK.
BTW some of the towns here who have had to rely on bore water in this drought have water bordering on undrinkable but the water where I live is soft and very palatable.
Personally I rarely drink water unless it has been diluted by tea, coffee or beer.
