I think I'm going to run a cold supply from the cistern - I hadn't thought of doing this and trying the whole thing on low pressure first. the only fly in that ointment is that my bath tap supplies are tee'd of the shower supplies. Will this cause a major problem, as they'll never be run at...

In fact, my mains pressure seems very high, so I was thinking of putting a mains pressure reduction valve on the entire system?. I could then ensure a common 2.5 or 3.0 bar pressure to both hot and cold, which should be ample for my purposes. The mixer bar I'm using, however, has an operating...
