Back to Back Bathroom Drains

FreshMeats · 11-16-2011, 02:34 PM

I am redoing a couple bathrooms that are back to back. I want to reuse most of the existing plumbing, so the attached image is what I have come up with. I read through the building code a little, but its hard to find a clear answer. Help?

Couple questions I have:

1) Is there anythign that says I can't exit my plumbing through the side of my vanity?
2) Can I use a paired wye and elbow to make the corner (i fogot to label it on the attached sketch).
3) If the above is acceptable can I just cap the end or do I need to have a cleanout and then have access to it?
4) Can the two different santees be stacked on top of each other?

1---hole in vanity is fine
2---no need for that Y with the cap---just use a 90--a long sweep would be good if it will fit.
3---No cleanout needed
4---Yes on the sanitary tees.

If the arm from the vent to the vanity with the hole in the side is more than 5 feet--add a vent.
