I had a plumber buddy by my project (complete remodel of house, relocating all plumbing in kitchen and master bath) the other day and he said if I run 2" that I don't need to vent my kitchen sinks (one main and one prep).
that sounds wrong to me, but it sure makes my life a whole heck of a lot easier if I don't have to as the sinks are directly below windows (and a stupid number of 2x6's that the window guys put in--two extra on either side because the row of windows was not level, so rather than pulling out the wrong trimmer studs, they just added more...)
so my questions are:
1 - is this true?
2 - do i need an AAV?
3 - what kind of fitting should i use? I was thinking a san-t and then capping off the top just in case I ever had to add a vent
4 - what size should I come out of the wall with? 1.5" or 2"?
thanks!
