I'm new to the forum, found it through googling my plumbing questions. It has helped already. I have done a lot of plumbing but this is my first project with the basement rough-in. Here is my question. I am confused about dry venting my toilet and keeping it in the path of the main drain under the slab. In other words the main stack will be dropping down the wall in essentially the same location where I would like the vent stack to run. I'm struggling figuring out all the connections for the toilet drain and vent; any assistance would be greatly appreciated. This is essentially new construction, so I have some flexibility in the location of the drain.
