So after running around several big box stores and plumbing supply houses, here's my mockup on the right. The left shows the WC and the mainline connection.To clarify, like in terms of the wye's configuration, but not in terms of what is upstream of the wye's branch. For a proper dry vent, the wye's branch needs to continue to under the wall, where it hits a 60 degree elbow to turn straight up.
Cheers, Wayne
It looks like I need to dig down several inches more for the shower drain to make the mainline connection. I also need to extend my dry vent arm to go under that bottom plate where I'll drill a hole and go up and make the connection to my existing dry vent line from the lav.
What do you think?
