Custom shower - water lines after valve
I have a 3/4" thermostatic valve to a 3/4" inlet of the diverter valve. the diverter has 3 - 1/2" outputs. Fixtures(3 body sprayers, handheld and head) are 1/2". I am on a well. Does it help my water pressure and/or volume to convert the 1/2" outputs to 3/4" then back down to 1/2" at the fixtures? i thought someone told me this but i can't remember why. or am i ok with 1/2" straight to the fixtures? the diverter valve is capable of running 2 of the 3 fixtures at a time.
