Using Hot & cold separate manifolds ? Why use 3/4" PEX to go to 1/2"
copper rather than use 1/2" all the way ?

Are there are tips the collective group can offer to using PEX 3/4 "
tubing? I'm using Watts Quik Connect fittings and will be tying
into 1/2" copper fixture risers.
Thanks.



Sure, but that is a reasonable question. Typically 1/2" PEX works fine for
domestic water but since no details were offered about why 3/4" was chosen
it makes sense to question it.

Quite true
