Change over to 3/4″ from 1/2″?
We stripped out the existing walls, and discovered the water inlet pipe to the house is 3/4″ to the shut-off, then “T”‘s off to 1/2” to the outside faucet and the rest of the house.
Since I want to move the copper up into the joists anyway, and the other half of the basement and laundry is now drywalled (boarded) off with 1/2″ PEX, is there any benefit to running 3/4″ PEX and sleeving down instead of 1/2″?

This short answer is meant to serve as a bump, so that a real plumber will see the question.
The greater volume of water carried by the larger diameter main/feed pipe allows more fixtures to simultaneously draw from the system without decreasing the pressure significantly.
You didn't say what type of 1/2" pipe you'd be replacing. That might be another factor.

If you have one handy.
Another suggestion; you could start a new thread here with a subject title that says "plumbing". That should attract one or other of the experts who post here.
When I'm doing plumbing on bath remodels or other stuff, I can usually get good answers from one of the guys at the supply house. Between the top two or three guys, they have enough actual experience to set me straight.
That isn't a foolproof method but as long as I put all the fittings together dry, before I pay up, I can leave with assurance that I've got everything I need and that I know how it should look.
In my experience with DIY plumbing, that's about 3/4 of the battle.
Likely only advantage in most houseswould be flow rate to the outside faucets.
Flow restrictors in everything else almost makes anything over 1/2" moot.
Caveat is that if someone is on a well and keeps pressure down* to 30psi (200kPa) and have drilled out all your flow restrictors then 3/4" or even 1" can help shower and washing machine flow. (my case)
* does save a few cents a month in pumping costs.
Thanks Art.You coming to Seattle for the Thursday night food-'n-bitch? I Think you still owe the first round from last year ...
BY the way, do you have any parts for Harleys in your pile? I could use some bags for an '06 Softail.Quality repairs for your home.AaronR Construction
