Hi all,
Hoping someone can help. I've not yet had a plumber out to check, thought I would get some opinions first if possible. What I perceive to be a problem may not be in reality. I have an unvented mains pressure cylinder in the basement set to 2 bar on the PRV from the mains which is correct from reading the manual. 22mm feed in and out of the boiler running off to the to the various rooms. The cold off the mains starts at 22mm but turns into 15mm in the basement and runs to the rest of the house.
The boiler serves a loft bathroom which is 3 floors up. 22mm feed all the way for hot and 15mm for cold. From where the boiler is its approximately 7 meters up to the shower. I've bought a new shower in advance - an aqualisa digital high pressure (bit stupid of me) and at the outlets for the hot its reading 0.8 bar and the cold 1.8 bar. So based on the shower specs anything below 1 bar is a no go.
Due to the height of the shower is this pressure loss entirely normal over that distance on a mains system? or is there potentially an issue somewhere. I'd just like to know whether I should sell the shower and purchase one that runs below 1 bar.
Thanks a lot
