Hi All,
Nice to see there's a place where a DIYer can feel confident about finding the correct answers (instead of asking the brother in law LOL).
As the title goes, I'm adding a basement bathroom to my home...It's a new home with the ''roughs in'' already placed (stubs protruding through cement slab). Since ''NEW'' doesn't necessarily mean ''OK or VALID'' I thought I'd clear it with the pros before spending time and money.
Here is what is laid out, facing forward, from right to left : lavatory, toilet, shower. I'm assuming that all of these are tied into the main 3'' drain that exits the house.
My concern is that the venting may be improper/insufficient? It seems that only the toilet as an AAV Studor connected to a vertical 2''x 8.6' abs pipe. I'm worried that every time the toilet flushes, it will empty the shower's siphon.
Here's a simple mock up for your understanding.

The shower drain is abs 2'' and ties into the 3'' sewage pipe (both of them are actually ''in line'' with each other) and are 12'' center from the back wall, the lavatory ties into the same 3'' abs pipe that is connected to a ''t'' junction clean out that has a simple ''back flow'' valve on it. Don't know if this is Ok, but would love to read your thoughts.
I'm hoping that I'll only need to install a siphon on the shower drain to complete the set-up...and not break the slab again to add another AAV. I'm planning on putting in an acrylic shower pan set in mortar with a Wingtite drain assembly with 3m marine grade silicone.
