Going through a remodel and looking for ideas here. Have a finished basement below the kitchen and are putting in a large window. The drain currently comes up where the window is going and the vent continues straight up.

Does the drain pipe run straight up and down below the kitchen floor? The vent can be run at a 45* angle above the sanitary tee. Will that angle miss the bottom corner of the window? Are you doing the plumbing? Are you homeowner or plumber?

Thanks for the reply. The plumbing below the floor is unknown as it was purchased with a finished basement. I considered the 45 degree angle too as I think this could get me around the 6" above the sink requirement for horizontal run of Vent. I'm not doing it myself but I want to be an informed home owner when the plumber starts suggestion options.

the plumber will need to open up the floor and ceiling. there are options here. so, frame the windows and then decide the best option.
remember there is 3 inches of space in the kickspace so the drain can always be run in that space over to the corner on the right. the arm from the san tee can run thru the back of the lazy susan behind the cabinet so it enters the sink cabinet from the side. then the vent can offset back into the outside wall and rise up into the ceiling to join the priginal vent. this is the long way around but least destructive to the framing.
