I've had problems with crimp PEX fittings on shower valves, they're less than 1/2" and tend to reduce flow, Definitely don't want to use them for tub/shower, they can create enough flow resistance to cause water to flow to the shower while the tub's used.
No, it isn't.Thats only on the tub spout drop.
Delta sells pex rough valves as do others. There’s no problem if the system is installed properly, and most of the time it’s fine even if the system isn’t proper. A shower only runs 2.5gpm and 1/2” pex will easily deliver.No, it isn't.
I've had complaints about lower flow on individual fixtures after swapping from copper to PEX with crimp fittings, shower valves in particular, the barbed ID is smaller than 1/2".
Unless they're the full port expansion type, no.Delta sells pex rough valves as do others. There’s no problem if the system is installed properly, and most of the time it’s fine even if the system isn’t proper. A shower only runs 2.5gpm and 1/2” pex will easily deliver.

There is a noticeable difference when switching from full ID copper to crimp pex, ESPECIALLY on a shower. I had a few callbacks on bath remods then decided to switch to Flowguard - no more callbacks.
The fact that those fittings will encourage flow back up to the shower head with the tub spout open is enough to keep me away.
This is why I buy the sweat/threaded rough valves and choose how to do it myself. Copper up and down. Then pex from the sides. Or copper the whole way.
No, it doesn't.Oh yeah ? Guess what.....1/2”flowguard will also make the shower head dribble when used as the spout drop on a tub/shower.
No, it doesn't.
If you can measure 2.5 gallon per min (or whatever the shower head/valve you bought was designed to output) after you install them yes have have done no wrong. I think the dripping was the issue here. Which is why I use copper.
Agree, I've also seen valves that come with built-in O-ring push fits, doesn't mean I'll use 'em.This is why I buy the sweat/threaded rough valves and choose how to do it myself. Copper up and down. Then pex from the sides. Or copper the whole way.
Use a metal transition drop ear, run copper as the stub, block it, as you're supposed to.You use 1/2” cpvc for tub spout drops ?
