 basement sink to waste stack with AAV

basement sink to waste stack with AAV.

Hi, I have a bathroom roughed in the basement already installed by the plumber on original construction. Vents for that are AAV; code in the county allows AAV.

I want to add a sink in another area of the basement close to a waste stack.

Is is possible to add a sink, trap, then vent via AAV, and drain to a new wye added to the waste stack?

Yes, you can use either a wye or tee in the stack to catch the sink drain. I usually use tee's .
