I'm in a 2 storey Victorian, with covered cold water tank in loft and hot water cylinder next to kitchen on ground floor.
I need to replace kitchen mixer tap. I understand I'll need one suitable for lower-pressure systems, but am unclear whether I need one which internally separates the cold (drinkable mains) water from the hot. I don't know whether current tap does this, and just push it all the way to cold and run briefly to flush it before filling a glass.
Do most taps have separate channels for hot and cold?
Thanks, Katie

Hi kathyfaull,
It’s part of the water board regulations that there are separate “channels” up to the tap nozzle, this is usually achieved by have a tube up the middle of the spout but you may still find taps (usually Chinese) that are just one tube. You should look out for taps that are designed to work with 0.5 bar pressure or less, Taps described as low pressure my need 1 bar or higher so seek out pressure rating.
