Need a little education please. Running new PEX throughout and I wanted to run 3/4 runs to the various fixture locations. I was chatting with a plumber and his opinion was that since you tapped into the various fixtures with 1/2", it was a waste of time to run anything other than 1/2".
I probably know enough hydraulics to be dangerous and when I started thinking about it, he seemed to be making sense? I know that at a given pressure you deliver a greater volume with larger pipe. And, when you neck down in diameter while retaining the given pressure, you just increase velocity? That's when my science breaks down.
So what is the best way to do this? I'd like to have good pressure with good volume at the second story showers and sinks. I know the toilets are good ay 1/2. Would it be helpful to run 3/4" to showers and faucets?
Thanks,
Dave
