Proper transition from PEX copper stubout to faucet?

buckybadger

In terms of code:

Can you just solder directly onto a PEX copper stub out without installing a shut off valve? (In this case, 90 degree elbow and more copper pipe coming off the stub out.)

I think I'd prefer to just solder copper directly to the stub out and install the shut off valve closer to the sink. I'm about 30 inches horizontally from the stub out to the faucet inlets.

I could install a shut off valve at the stub out and then another under the sink, but that seems a bit stupid.

Is the wall open?
Sure would look better to move the sub out over so it's under the sink behind the wall.
Posting a picture would sure help.

There's not really a wall; this is for an island bar sink.

Hmm, that sink looks familiar.
Sweat on your adapters and pex over to the sink. Put shut off valves within the distance speced by your code

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.
