I'm doing a complete remodel of our hallway bath on the second floor. When done, I'll move on to the master bath. This house is 50 years old and I'm on well water and the main line is 3/4".
I've ripped out everything to the studs and floor joists including the existing copper plumbing. I'm replacing with PEX.
I've considered the different arrangements for PEX - home run, trunk and branch, and zone. I'm inclined to go with home run but I can be persuaded to go with one of the other approaches. My objective is to maximize volume / pressure at the shower and eliminate pressure change at the shower when another outlet is opened.
As the bathrooms are almost directly over the water supply in the basement I don't expect much delay in getting hot water to either bathroom. The PEX runs should be about 50 ft.
Everything I've read says I'm probably okay with 1/2" to the tub/shower combination but I'm inclined to up size to 3/4" to reduce any pressure loss. I'd home run everything else although I'd consider trunk and branch for the cold line to the sink and toilet. I could also share these other 1/2" lines with the sinks and toilet in the master when I redo that room.
But assuming I home run everything, I can't find a manifold that includes both 1/2" and 3/4" outlets? Does such a thing exist? I know I'm not the first person to do what I'm suggesting.
Thanks in advance for any advice.
