What is the question?

Apple_pie_ not sure if I should do a soffit around an oddly placed drainpipe Or contact a plumber.

Thank you Hallet. I’m thinking this might be a bigger job than I thought in order to get the proper angle for drainage before I can close off the ceiling.

Contact a plumber. Also be aware that noise from draining pipes can be a problem, for example, when a toilet is flushed. What was quiet before may not be quiet after re-routing. YMWV.

A good plumber can re-route. You don't need anywhere near the current slope.

Thank you apple_pie_order. You are correct about the sound. I’m also researching drain sound proofing.

Thanks Worthy. Do you think s plumber would route it through the joist?

why ask us? get a professional to present a few options. on site.

Your plumber may need a magic wand in their toolbox.

Dana-

Plumber are notorious for notching joists, and this is something you want to avoid to maintain structural integrity. A good plumber should be able to fix this without doing the quick and dirty approach of unnecessary notching. If it were me, I'd try to change that diagonal to a right angle. You might still need a soffit along one wall, but the rest of that should be able to go up into the ceiling and run parallel to the joists. This will be a longer run, but it looks like you have more than enough slope to accommodate that. Get a good plumber and tell him that you are looking for a solution that eliminates notching, if possible. If notching must be done, it's always better structurally to do it toward the ends of a joist rather than toward the center. Here is a good explanation of the dos and dont's of notching:

How joists work

Thank you KUDZU9. Thank you for you sight and perspective. I also received a recommendation I feel may be a great fix. Which is see if I can make a hard right into the soffit I built and tie into the roughed in powder room on the other side of the basement. This would totally avoid having this drainage pipe go across the room.Yesterday, I visited my local Home Depot. I received a great education and hands-on demonstrations on how to layout, cut and connect PVC pipe. I plan to speak with a plumber from my job to see if they might help me out as well. I’ll keep everyone posted!!!!

Sounds promising. Good luck.

It would be better to call a plumber. He will solve the problem I hope forever.

And during reading this forum, one question appeared in my head: need plembers a plumbing website templates or not?

It is better to call them or to find information in Google about their services and contact them online?

What will be easier and more comfortable for everyone?

Sounds like a reason for discussion.
