I'm trying to install a new tub and I need to modify my plumbing slightly as the new drain needs to be on the other side of the floor joist. I'm trying to avoid drilling a new hole and to reuse the hole that's there now since it's already improperly drilled(by the builder)
The diagram is drawn as if one is looking down into the open floor everything there is in the horizontal plane. Grey circle A is the closet bend + flange B is the current drain shoe and ptrap C is where the new ptrap/drain shoe needs to be. This is how everything is now done by the builder and inspected.
I'm trying to figure out if 1) the 1.5" vent is needed since the shower drain ties into the 3" vent and if it is how do I bring it to the new drain location without drilling the joist and running vent horizontal in the floor. Also there can't be a bulkhead or anything below due to cabinets. This is a second floor bathroom so both of these vertical vent pipes go into the attic where the 1.5" vent ties into the 3" vent and then they go out the roof.
I know the diagram isn't ideal I tried making an isometric drawing but it failed miserably; but I'll draw anything else that's needed to answer my question.
