Hi, great forum and site by the way. I'm taking on my first major plumbing effort by installing a new shower with 4 1GPM body sprays, rain shower head, and wand. The rough valve is a combination volume/temp + 6 way diverter from Delta with only 2 fixtures running at max (ex: 4 body sprays + shower head). I used an existing 1/2 cold and 1/2 hot from a soaking tub that we demolished. I suspected that the supply would not be ideal, but wanted to confirm first before deciding to upgrade to 3/4 supply. After testing the installed fixtures on the 1/2 supply I noticed a notable drop in pressure when two fixtures run at once.
Here's what I'm thinking about doing and would appreciate any guidance. In the attic I have a 3/4 cold supply going to a tankless and 3/4 hot coming out. I was considering tapping into those with 3/4 tee and running 3/4 hot and cold to the shower (about 25 feet away). Once in the wall with the valve, I would reduce these down to 1/2 hoping to not have to upgrade the delta valve. Any feedback is appreciated including if there are better ways to solve the problem (aside from hiring a plumber because that would prove my wife right and I can't afford any more of those scenarios - she already has too many to count ;-)
