PEX pipe under joist to be changed to through joist plan

[Teamplez]

Good afternoon all,
I am finishing my unfinished basement. Its been a slow go. SMH.

I have come upon a plumbing issue while finishing my wall framing (See 2854). The PEX is under the joists. I need to be able to put sheetrock on the joists. In order to do so, I am looking to run the PEX through the joists (middle third of 10" joist).

Current plan:
1. Shut off water
2. Cut the crimp ring or PEX 3/4 to the upstairs fixture
3. Plug both openings
4. Move pipe through the joist
5. Add new crimp ring
6. Remove plugs
7. reconnect to T-connector
8. Crimp the crimp rings
9. Check go no-go
10. Turn the water back on.
11. Done?

Do I need to run pressure tests like new construction?
Is there anything else I need to do?
Should I add any other preparatory steps, do the ones I listed above in a different order?
I will have a bucket and rags avail for water in the pipes.

Appreciate any advice on what might be a very simple question. I just want to make sure I am good before I actually have the ceiling closed up.

Thanks Much!!

Pete

Use heavy Nail protector plates if too close to the surface of the joist.

Why don't you put up strapping instead ?

Do not drill holes closer than 2" from the top or bottom of the joist. Pressure test would not be needed. With water turned back on leave it open for a few days to be sure there are no drips. Take some pictures for any future reference.

As a suggestion, since you have to go around the 3" PVC pipe, it may be a bit tough to thread the PEX pipe around it. You could cap of the at the tees or use a coupling and make the turn with a tee by the support beam. Make the U turn back toward the where the pipe needs to to go. At the beam build out a small soffit for the pipes. If you have the space try to use bend support brackets for the PEX to make 90º turns. It can eliminate some couplings.

I considered it. Just trying to retain the ceiling height. Thank you for reading and providing input.

Thank you for reading and providing input. I think through the joists are ~ 4in from bottom of joist.

Thank you for reading and providing input. We measured to make sure we were in middle third of joist. Appreciate the feedback on the pressure test. Taking lots of pictures. Thanks again.

Will do. May do that, even though we think we should be good being in the middle third of the joist.
