I have a wet bar sink that I am putting in the basement. I have the hot and cold water lines all ready to go but I am now stumped as to how to connect my sink drain to this 4" inch waste stack.
This sink is in my basement. The 4" line that you see below is a waste stack for my upper floors. It is one of two stacks that I have in my basement.
My questions:
1) how can I tie into this stack for a waste line from my sink that I want to put in?
2) my sink is going to be right next to this 4" waste line. Will I need a Air Admittance Valve?
NOTE: My sink will be to the right of my supply lines and to the left of that vertical soffit that the 4" waste from upper floors is located.
