So, I got my 2nd floor bathroom floor open and found a convoluted mess on the vent plumbing. It all met the code as of 1990.
My problem is that we need to move the toilet a few feet to the right. Problem is they vented it at the hip wall and not the side wall.
We will be moving the sink closer to the hip wall, near where the toilet was. The old fiberglass tub-shower is being replaced with a 1930's cast iron built in. We are going to build a platform across the rear 4 feet of the bathroom and raise the tub up about 7 inches. The issue is the long vent distance fore the toilet.
It will be about 8 feet. Too long under the UPC. The second floor is a truss system so I do not want to punch any more holes in that 11 inch bottom chord. They did that over by the tub and I can see it cracking.
The only thing I can think of, if the depth allows for it, is to use the existing sink drain as a vent line. If, I can get it to tee in at a 45 degree angle. Then the toilet would have two vents along its run. See the photo for layout and any suggestions would be appreciated.
