Plumbing vent question. Diagram inside

bhom920March 17, 2012

Hi I need advice on some bathroom plumbing. I have the national plumbing handbook in front of me and this is what i've come up with. I'd like to get some insight on if i planned everything out correctly. Keep in mind the main 3" house drain is sitting under the floor about 6-8inches. It already has a kitchen and clothes washer further up stream and another bathroom downstream.

Do you think i need to extend a vent from behind my future sink and tie it into the 2" stack? or is it close enough to not deem it necessary.

no.
This is wrong in many ways.

Someone else may post more specific things to do, to make it workable.

Yea i realised i might have screwed the theory up. I just updated the drawing with the revisions i had. Althought i feel a portion of the vertical 2" vent is unecessary with the changes i made.
