I'm in the process of refurbishing my bathroom. I'll be replacing the existing bath with a walk in shower. Will be installing a thermostatic mixer valve fed by mains on the cold side and a combi boiler (Logic Combi c30) for thr hot.
Ideally what I'd like to do is have the mixer valve at the entrance to the walk in showervand the shower head at the other end. I have to raise the shower tray anyway to accommodate the waste into a communal pipe. This provides an opportunity to take the mixed water pipe from the mixer valve under the tray and then back up to the shower head. I've not measured it precisely but this would mean a pipe run from the top of the valve to the shower head of somewhere between 4 and 5 metres.
So the question is this. Should I expect a pressure drop at the shower head compared to the mixed water pressure coming out the top of the valve. If so how would I measure that drop without actually running all the pipework I.e is there some kind of mathematical equation for this scenario. Or would I get the sane pressure at both ends with the combi boiler pump doing the work for me?
