I am owner/builder trying to get my rough-in plumbing complete. We are governed by UPC. I finished the master bath venting and wanted to confirm that what I did was OK. I ran a 2-inch main vent line horizontally to tie all the individual vent lines together. To get to the branch vents, I used 2-inch San-Ts laid on their side with a 2 inch branch line to each fixture. I have the San-Ts oriented for drainage. There is no place for rain water to collect. All horizontal lines have 1/4 slope. I have a cheat sheet and not the full code. UPC 905.2 says no flat horizontal dry vents. I assume this means when you are tying vents into drainage lines. My question is once in the attic and all vent lines are dry, is it legal to have a San-T laying on its side to tie branch vents to main vent line? Since the line is always dry it seems as though it is fine, but I have been wrong before.
Thanks,
Mike
