What size is actual pipe connection? 3”?

4" but It's not american plumbing dimesions. The female (top) will require you to remove some material on sch 40 pvc. It can be done quickly and even on a lathe. Bottom part can be connected with no hub style coupling. Its a great fitting option if you dont have a spot for a horizontal backflow. Dont know why we dont have alot of these vertical waste back flows here.
