I'm working on installing a toilet in the basement of my 1950 home in Seattle. I've broken out most of the concrete around the old floor drain, which I don't need any more (it used to drain the utility/laundry sink, but I've since connected that to the stack with the black ABS you can see on the left. I'm planning on just getting rid of the floor drain in the center, and installing the toilet flange just to right of it (near the red trowel). I'm thinking I'll connect in to the main line (the black cast iron, still slightly under the concrete) with an PVC wye and some no-hub Fernco adaptors. My question is, do I need the vent pipe that's currently dropping down at an angle to pick up the floor drain? Should I drop it straight down on to the main line with T connection to increase the venting for the second toilet? Thanks for any advice!
