I have a normal two story 1980's house with a conventional hot water setup, hot water header tank in the loft, hot water cylinder (cistern?) in an airing cupboard on the 1st floor.
I have recently bought a 'Trevi Boost' venturi shower valve which demands its own feed from the hot water tank, and I am wondering whether I can simply put a Surrey Flange on top of my HW cylinder and then go up into the loft, across the top of the joists (below the level of the header tank) and then down into the bathroom. Would that work? I guess I could do a test with some hose, but I thought I'd check here before I do something rash.
Its just that I'm don't want to go through the hassle of lifting floor boards and notching joists. Chipboard floors are a PITA.
Thanks in advance
RJ.
