1/2" valve big enough to run 2 showerheads?
I want a system in my shower that would be able to run 2 showerheads simultaneously (handheld + regular head or smallish rainhead). No jets or body sprays.
Is a 1/2" rough in valve large enough, or would I be safest with a 3/4" rough in valve?
Is 3/4" overkill?
