Proper transition from PEX copper stubout to faucet?
If you have pex in the wall, and copper stubbed out my question is : How much copper before the transition to pex? 6" ? 12" ?
I haven't had to try soldering next to pex like that, but I do know it softens if you heat it with a torch. IF you happen to have any stress on the joint and you heat that pipe enough, the connection may come halfway apart. If you can't see the connection, you won't know until the water is back on.
