This video talks about sizing a basic wet vent system. It covers code clause 2.5.2.1.(1)-a,j All references are from the 2015 National Plumbing Code of Canada.
Love the video’s, pls keep them coming. I appreciate your time and effort for making the videos . I don’t do a lot of abs, but being able to watch over and over again is very helpful! Thank you!
The 1 1/2 bathtub drain in those pictures is draining into the wet vent and it is not individually vented. So the wet vent is also venting the bathtub?
Never come across a 6" wet vent. According to the table at 2:47 it is not permitted. Further to that, if I saw my employee running drainage like that, I would ask them to give their head a shake. Huge waste of money
Excellent excellent Videos and of course they’re buried on UA-cam and very hard to stumble on. You must have terminated a vent stack in some UA-cam executives jewelry closet or something.
how come the wet vented system without water closet which serves 1.5 FU for the shower and 1.5 FU for the bathtub is Ok with 1 1/2" wet vent? 1.5FU+1.5FU=3FU so it should be 2" wet vent. that part is confusing. thank you!
When you total up FUs draining into a wet vent, you never count the last/lowest connected fixture, in this case the shower. The shower is being vented through the wet vent but it's not draining into the wet vent. (The wet vent ends at the shower wye connection, therefore the shower is being drained into a Branch) To think about this another way, the wet vent will never get filled up by water from the shower (Unless the drain gets blocked downstream in the system somewhere)

Yup, that's how it works
Thanks for creating these videos. Very well explained!
what about using the 6" wet vent without serving the toilets, what's the maximum load allowed?

wow, thank you for taking time, really clear explanation. Im in the middle of my reno so that is helping a lot.
Thanks Kelly. I write my IP in 4 weeks so this is great review.
Great videos, very helpful. thank you
3:21---here in Ontario you can't put a double wye on the horizontal, Otherwise very informative video!
there's literally nothing wrong with the set up shown in the video, the system will drain just fine with 0 risk of clogs/leaks
