|In response to Re: Vent Pipe|
: How large does the vent pipe have to be for a shower, toilet, sink setup where all three go to the same air vent, and the largest drain pipe is 3"?
: Is there any code, or logic to follow? Thanks.
the vent needs to be 2" as long as you are venting a stool.if you vertical wet vent the stool then the wet vent needs to be 3" then back to 2" after the drain. 1994 upc code.
