Bathroom water pressure estimate?

[terryhawkins]

Is there any way to guess or approximately work out the water pressure from taps in a bathroom?

We are replacing the bathroom and have found some taps that require 0.5 bar pressure and wonder if these are even an option.

Our second choice of taps say minimum of 0.2 bar.

Any help would be appreciated.

The large tank in your loft is the head of water. Hight from top of water level to tap is head of water. as near as makes no odd 10 meters hight equals 1 bar of pressure, 5 meters equals 0.5 bar pressure, and so on.
