Temporary termination of new water lines

Hello guys

I am in the process of finishing a basement. I need to tap into the existing water lines (pex) for the bar and bathroom (2 hot, 3 cold).

I have the pex supply lines meeting up with a copper 90 degree elbow and then coming through the wall (no drywall yet though).

If I put the shutoff valves on these pipes (compression fittings) they will need to be removed when the wallboard goes on and I have had no luck putting a compression fitting back on after it has been removed. It always leaks for me the second time around.

If I sweat on a copper cap I am going to have to cut it off where I'll end up working very close to the wall because the elbow is only a few inches long on that end.

Any suggestions would be appreciated.

Post a picture---I can't follow the PEX--Copper description---Is there a reason that you can't finish the piping now?

make your copper stub longer so that you don't have to work so close to the wall.

Well, this is similar to the copper elbow I was looking at:

What I saw at the home center was similar but it was open on the non-pex end and that end was much shorter.

It looks like this piece is meant for stubbing supply lines through walls and then cutting the end off later. Is that correct?

Now that I know that this piece exists, it's exactly what I need. Thanks!

sweat a mip x copper adapter on the stub out. cap with a galv cap. At trim out use IP angle stops.

Or cap copper with sharkbite caps. They can be removed at trim time without cutting the pipe
