I have a question regarding the branch size for the bathtub. I have researched it and have found conflicting information both in books and on this forum. I'm under UPC and in the state of NJ. Attached is a plumbing riser that I submitted to the inspector.
On the second floor bathtub, there is a 1.5 inch drain that has a 90 degree horizontal turn. Eventually when it meets up the lav branch (vanity sink) I was planning on upping it up to 2 inches.
So my question is... is the 1.5 tub branch with the horizontal 90 (long sweep) acceptable?
Any other comments or constructive criticisms are welcome.
