We're adding a bathroom to the house, and a friend is chewing my ear off on this, so I'm hoping to find some closure here
Currently we have 1" to 3/4" copper throughout the attic. The plumber for the new bathroom is planning to come down with 3/4" from the attic, and then branch off with 1/2" for the shower, and sink+toilet respectively (shower has its own 1/2" runs, and the sink has its own 1/2" runs - cold shared with the toilet.).
Each 1/2" run is approximately 15' long.
My friend is advising that the plumber should make each run 3/4", or else we will lose pressure. Is there anything to this worth considering?
Thanks in advance!
