Home owner/builder new construction vent question.
California.
I have a two story attached addition I am building.
Does the 3" main stack have to continue through the roof or can I reduce it to 2".
Main stack services a washing machine on the ground floor and one toilet, one double sink lav, one shower on the 2nd floor.
I also have a ground floor toilet with its own 2" vent. Do I have to keep the 2" vent size all the way to the roof?
Thanks guys.
