wet vent?

waiting for my ipc book to come but in the meantime i still have a ? on wet venting. how do i draw an isometric drawing of a bathroom(toilet ,sink,tub) and directly behind bathsink is a kitchen combo sink.if you can do this with minimum pipe sizes it would be most appreciated.thanks

The first question is ...does NY allow you to wet vent a kitchen with a bathroom group...I am guessing no, but let's get the input from some NY plumbers

it was on a test in ny.ive never done it as we individually vent our fixtures,that is why i am having trouble with this,

depends on who's code you are using but, it used to be that all sections of the drain that being used as drain and vent had to be 2" minimum, however the IPC now allows that to be 1-1/2
