ive always thought this was a no no. But ive been told all cold water comes from the mains and the tank upstairs is just for hotwater? true?
What's the point of going downstairs if you're in bed when the bathroom across the hall gives you EXACTLY the same water?
Ah right, *imagines* ugh *throws up*
How old does old have to be?
My house was built in 1992 and it had a cold water tank until I did away with it.
