kitchen sink, no trap no vent, HELP!
We have an 1892 kind of renovated brick house. Our double kitchen sink stinks because it has no trap, and the waste drain is vertical beneath the sink drains. I don't know how to even put an s-trap (I know not to code) or p trap without the space, or try AAV or cut the wall and vent outside with some weird drain arrangement.
There is a joist which prevents easily getting a pipe at the back where it is supposed to be. I don't want to just hash it again like the previous owners did, but I have no idea how to do it as "proper" as possible with the limitations in place.
after 10 posts I can submit pictures which I am sure would be far more useful than my description
