Can I tie in my shower and lav to my 3" horizontal water closet drain? My shower and and lav are at a higher elevation then the water closet drain. But the shower is wet vented by my lav and the water closet is within 9' of the vented vertical stack.

The water closet drain runs below the floor joist and is concealed with a soffit, the lav and shwr are running through the floor joist at a higher elevation .

That should work.

I couldn’t help but notice your offset closet flange I’m not sure if you have much experience with them but they can cause issues. I’m not a big fan of them personally.

I just wanted to give my 2 cents.

As for the other it should work no problem.
