    Default Help!!! Single Bathroom sink to Dual bathroom sink drain

    Name:  untitled.JPG

    Any help is greatly appreciated.
    Im trying to figure out how to properly drain two bathrooms sinks from one existing sink.
    The diagram shows where the drain and vent stack come from in the wall and show the dual vanity setup i am going to have.
    The issue is all work has to be done inside the wall, which is not load bearing, because i have a drawer system in the middle that will not allow any plumbing from one side to the other.
    I need to know what are my options and if any of the options i have on the diagram will work.
    I live in Canada, if that will help with code issues.

    Thanks

    option 1 is acceptable as a wet vent set-up as long as the piping between the trap and vent of second(furthest from vent) sink meet wet venting requirements...except you need to use a Y not a TY for first sink

    I am not sure about Canadian codes, but neither would be acceptable here, because they both have the right hand sink flowing past the left hand one' s connection without a vent for the left hand one. We would have to lower the horizontal line and install a vent for the left hand sink, which could then vent the right hand one.

    sorry, meant option 2...as for requirements... distance within 1.5m between trap and vent...not more than 135deg. change in direction, not more than 1 pip size diam fall...etc... refer to plumbing code book for all requirements
