Seems like manifolds are geared to 1/2". I've already run 1/2" homerun from 3/4" manifold with six 1/2" ports servicing 1.25 baths, kitchen sink, dishwasher, and clothes washer. Now I am having 2nd thoughts on the tub/ shower. The manifold and WH are directly 2 floors below in the basement. GPM is 7-8 at 60-80 psi. I know pex is smaller than Cu i.d. But at least it's Uponor. Should I upsize to 3/4" with reducer near the valve? My concern is adequate water supply volume. Please gauge the strength of any recommendations.
THanks.
