I'm working with a 3/4 Grohe thermostatic rough-in going to 3/4 volume control rough-ins.
Question: Should I reduce down to 1/2 inch copper prior to the pressure loop OR should I build the loop in 3/4 copper and reduce at the "Ts".
Is there any advantage to using 3/4 closer to the end fixtures?
Thanks
