Hello all - first post!
In my basement I have a 3" copper stack that extends straight out through the roof. It services only the 3pc bathroom on the main floor.
I would like to add a bar sink / dishwasher in the basement and tie into that stack. It would be approximately 5' from the stack.
My question is do I need to add vent pipe as well or is the stack sufficient? And if I need a vent, where is the appropriate place to tie it back into the stack?
Attached is a diagram...
