I’m finishing my basement and there is one, lone pipe that runs along the ceiling that I’m facing having to put a soffit around. It runs along where I intend to have my home cinema room and it just throws off the symmetry and overall aesthetics. Not to mention it’s going to be a pain to frame and drywall around. I’m wondering if I can relocate the pipe in the ceiling farther out in the room. The floor joists are 16″ on center but so it may look like I’d have to put the pipe in, in short chunks. However, at the end of the room, the floor joists run the other direction and I’d have about a 4.5′ section where I could feed pipe in. A bit of work and a few joints but I feel in the end I’d be happier with the results. What do you think? I feel like, as long as everything is running downhill toward the floor, I should be just fine. (See pictures)

What is planned for the room on the other side of that wall (doesn't appear to be finished space)? If it's a closet or dead space, looks like you could go the other direction out of the floor (I assume that is just blocking behind the sanitary tee, above the beam) and run the pipe on the opposite side of the wall? The pipe that makes a U and ties into your drain line comes from that direction anyway (and could be tied in on the "new" side). Just a thought
On the opposite side of that wall is the stairwell, hallway and bathroom. All of those spaces will be finished eventually so I don't want to penetrate into those (especially the stairwell). The Idea is that instead of the sanitary tee below the floor, just use an elbow. Then put the sanitary tee off the corner of the U bend and head down the wall inside the floor. According the floor joist specifications, I have to be at least 1' -6" away from the supporting wall in order to make a hole big enough to route the pipe. My only other concern is that a couple of the "joist bays" have vent pipes running through them. I will have to change elevation by a couple inches to get over these pipes. I don't expect that will be an issue as long as I change elevation up and not down so as to not trap water in the low spot.
yes it can.
Are you sure it all is vent?
either way, no problem moving the pipes. nice project. be prepared for there to be liquids and other stuff inside the pipes.
Bulkheads are also a possibility, but you are in control of the project.
Good for you to understand the slope requirements, and guidance on hole locations from the joist technical folks.
If I cut this Tee off, am I going to have enough room to put the new fitting on? Even if I do, I'll likely have to go with a larger radius in order to get my centerlines right? Or could I just use a pipe extender?
