Hello. I have an appx 1 inch OD threaded nipple coming out of my water meter that goes to a bushing to a slightly smaller lookinga 3/4 cpvc line that feeds the house. The cpvc line reduces to 1/2 inch too soon and I have contention problems when more than one fixture is running. I want to upgrade the 1/2 to 3/4 then distribute directly to fixtures with 1/2.
Thinking of going pex, but wanting maximum output. I don't know the true diameter of the nipple coming out of the water meter but wondering if I should go to 1 inch pex to some point of splitting...? Any benefit to this? Thanks.

3/4 should be sufficient to supply most water demands. what kind of pressure do you have currently? how many fixtures of what kind do you have. how far from the house to the meter? is this a multi-level installation?

I never measured the pressure but seems sufficient when one sink is running. When toiled flushes significant drop off of water flow elsewhere.
We have washer in basement with indirect hw heater/boiler, kitchen and half bath on floor 1, and main bath on floor 2, and plan to add a master bath on floor 2.
I would rather spend extra bucks on larger pex if it would help since 3/4 pex is smaller dia than cu.
Also thinking about how to distribute...manifold vs tees.
Thanks.

i am partial to manifold, home run system.
use a 1 inch copper manifold with 1/2 mini ball valves for the cold. locate it close to the water meter.
use a 3/4 copper manifold with 1/2 mini ball valves for the hot. locate it stratigically so you can run a gravity recirculating line back to the water heater. insulate all the hot water piping.
