I'm installing a Grohe SmartControl 1/2" valve with two 2.5 GPM shower heads that can potentially run simultaneously. I've gone thru all 1/2" vs 3/4" pex threads on this forum but I'm still not sure which one should I use.
It's a second floor bathroom with 3/4" trunk copper line that I'm going to convert to 3/4" PEX and run 1/2" PEX branches to the fixtures. I'm using ProPex/Uponor expansion fittings. Water pressure on the first floor is measured at 80 PSI. Shower branch line is approximately 7 feet long.
Looks like 3/4" for the shower is a safe bet, but it's a bit inconvenient to run and it looks like Uponor doesn't manufacture a 3/4" PEX to 1/2" male NPT adapter. Other than transitioning back to 1/2" copper using this fitting and soldering on male NPT adapter is there any other way to connect 3/4" PEX to 1/2" female NPT? Or do you think 1/2" PEX should be sufficient in my case?
Any help is much appreciated!
