Does one measure head of water from the bottom of the tank or the top? I'd
assume bottom.

Working in a place last week, old building converted into bedsits a few
years ago. Water tank in a cupboard on a metal stand with the hot water
cylinder underneath.

Bottom of the tank was 4' from the floor. Bathroom on the same floor a few
feet away.

Water pressure was terrible, toilet cistern took around 10 mins to fill.

ISTR that to get 1 bar pressure you need a 10 metre head? From the bottom
of the tank was roughly a 1 metre head.

Are there no regs about this sort of thing?
