Hi all, quick question about a shower vent . So the pipe on the left in the picture is in the way for adding a stud for reinforcement for a frame less shower door. I need to move it over a couple of inches, but I’m wondering if I can just put a 90 degree elbow at the top and bottom, or maybe 45’s. I don’t know a lot about vents, so is this a bad idea? Is there a certain height the elbow has to be? Thanks!

No 90s.
Yes 45s.

90s are allowed. A vent 90 has a shorter radius than a medium sweep 90. It can be used in a vent but not in a drain. Just make sure everything goes up hill.
Would it still be going uphill if there is a horizontal section from the 90?
you need to force it up slightly. Just make sure it's not sloped down. I just had an inspector get me on that. If you are drilling holes for a horizontal run, you need to make them go up. This is assuming you're using plastic pipe.
Perfect. I don't need to move it far, so no real horizontal run required. I'll just lean it a bit. Thanks so much for your help!
