Double vanities, each vented in separate stud bays

Hello all,

I'd like to vent these in separate stud bays and avoid horizontal runs that would sever the wall completely. This also allows me to feed the pipe from below and open the wall selectively.

I am planning in 1.5" for the blue runs in the drawing. And 2" for the red runs which service the wet vent. This seems to be OK with UPC 2015 as I read it. Any comments about the arrangement?

Shawn

    I am not a plumber but I think you san tees could go in the vent lines without the upper and lower Y fittings. But we will see what the experts say. What you drew is fine as far as I know

    Hi, As long as they are above the rim of the sinks, you may be able to simplify all this and just use air admittance valves. You would need to leave access to them. Some folks hate them, but they are code and are useful at times.

    Yours, Larry

    Hi @Youngplumber , I'm corrected! It seems UPC only allows then in island sinks. My code (in California) is different so I've installed many of these and they seem to be working fine. Guess California physics are strange enough for the AAVs to work here. :p

    Yours, Larry

    I was considering venting the toilet with the wet vent right after the bend, and putting the shower on the vent riser coming from the kitchen. I would need to connect the shower to the kitchen vent vertically or at a 45 deg min angle until I was 6" above shower curb? Is that how that works?

    Not a plumbing comment: But, you need much better lighting for your mirrors.... Find a lady friend to assist with a walk through of a local home supply store or the internet (and they may want different mirrors). I've got multi-bulb light fixtures above all the bathroom mirrors in my house (including mine - I appreciate the good light as well: Note that we have all of those on dimmer switches so that they are not always on super bright.

    Hello Perry,

    These mirrors have an integrated LED ring around them on the front (activated by touch), and are also backlit for drama. No way to see that from the image though...

    Dimmers are essential! The general lighting for the bathroom is a hidden light source rope light on a dimmer that washes up from the cove on the wall.
