I am installing a half bath and am trying to figure out if my venting plan is a good one. I was planning on venting my toilet by using a side inlet elbow directly below my toilet. The waste drain line is 3" and the side inlet elbow is 2". I thought this would work until I got a code book from the library and it says in there "no flat dry vents." The diagram it shows the vent fitting must be angled at least 45 degrees up from horizontal. The side inlet on my elbow is horizontal.
Can I use the side inlet elbow to vent the toilet or not? The code #'s listed are, IRC 3104.3 and UPC 905.2. I'm confused.
Thanks,
Mitch
