Anyone have any thoughts regarding this… need help before I make a major mistake lol.
Hope this helps.. by the way, tub spout is primarily for testing the water before turning on the shower head so lower volume there is ok. So I guess my main question is should I flip the main 304 valve upside down to increase flow to 728 3 way transfer valve and if so do I need to do anything else besides flipping the cartridge too? Looking at the 304 valve i do see that the bottom port does have a slightly larger diameter discharge hole than the the “top” hole. Also would 3/4” pex “expansion” be ok for tub spout or is copper/brass mandatory?
I’m now wondering if doing things this way will create a problem with water flow diverting down to the tub spout if I use volume controls on shower head or hand sprayer… would that back pressure be allowed to exit at tub spout or how does that work?? (OCD at its finest lol)
