I used to have a multipoint, and the old shower had a pressure reducing valve on the cold feed - are valve-equipped flexible tails a suitable replacement for restricting flow ?
(thinking of a tap/shower mixer instead of a seperate shower mixer)
Well, a pressure reducing valve isn't just a flow restrictor. You can get thermostatic shows designed for the differential and varying pressures from a multipoint/combi,
but possibly not as part of a tap/shower mixer.
I`m not sure what the unit was exactly, a white plastic lump with what appeared to be a diaphragm and an adjusting screw underneath. I don`t even know if i`d need something like that in place to make it easier to control shower temperature (the cold has a much greater flow rate, so the ability to reduce flow might make it easier to control) - any loss of cold water flow to the bath itself wouldn`t be an issue as far as i`m concerned.
