I am changing plumbing in my house. For upstairs bathroom toiltet I installed 3" closet bend with side 2" inlet vent connection. I have 3" sewer. Yesterday, a plumbing inspector told me to put 3" X 4" closet bend with 2" vent connection. He mentioned the name of the part but I don't remember. I did a google search on parts and the only suitable part I found is 3" X 4" street closet bend with no vent inlet connection. The only way I can connect the vent to closet bend is to the side of the bend. Can some plumbing expert advise me what part I need to put for toilet? Also I don't understand why 3" X 3" closet bend is not good.
