So, you're trying to move the toilet location in the first photo of the exposed floor. And try to move/hide the exposed pipe in the 2nd photo of the finished washroom?
Are the pipes we see in the exposed flooring the same as we see in the finished room?
For me I like to see an architectural style layout of what you want to build and where the plumbing is in relation.
Yes they are the same pipes. The two bathrooms are above and below each other. Basement one is finished, The 4" stack beside the cat5 cables in the rough in photo is all the way out in no mans land in the basement washroom. This is what Im trying to eliminate.
The toilet that I want to move is currently connected to this stack before in 45's and hits the stack that's slightly covered by drywall.
When this is all said and done my intention is to fur out that little protruding bit and have an access door for the clean out.
I'd like to extend the part in the drywall, 45 into the drop. To the right of this will be a toilet and bathtub, to the left the stack will continue to the roof and pickup the sink.
Drainage will be flowing into it from both directions.
Im not sure if im allowed to use a Double Ell, or if it even comes in that size, or do I use a Double Y and Cap the center
