Toilet wet venting

[steven anderson]

wet venting a toilet. I've seen a 3x2 inch rolled up to a 2 inch vent. can I use a 3x3 inch since my main vent is 3 inch and does it need to be rolled up or can it be flat or just some slope?
thanks

Are yo asking about a "wet vent" or just a "flat vent"? They are NOT the same.
