This video talks about sizing a continuous vent. It covers code clause 2.5.2.1.(1)-g All references are from the 2015 National Plumbing Code of Canada.
Thank you for these series! I've been looking for plumbing videos for over two years now. I'd say yours are among the best I've seen, most videos out there are demos and walkthroughs, yours are very well explained for those of us that love to geek out!
Quick question- if the lav is 1.25”, the wet vent is 2”, and the continuous vent is 1.5” like in your first example, what kind of tee do you use there? Where do you put the reducers/adapters, particularly on the lav side?
You would use a 2" x 1½" x 1¼" TY But let's be clear, 1¼" drainage is almost never used anymore. (It's considerably more expensive than than 1½") Therefore you would just stick to 1½" for the lav trap arm, and a 2" x 1½" x 1½" TY
@@JERRY_ONG If it's sized properly, yes you could end your wet vent at the two lavs on the right. As the plumber, you get to do it your way as long as it is to code.
So where could you tie in your continuos vent ? Would it have to be above the upmost fixture or anywhere closest to the main stack vent , tie in spot wouldn’t matter ?

In this case, we consider the sow pipe in the middle as our wet vent. Why not consider the right sow pipe with two LAVs as the wet vent?
If we consider the sow pipe on the right as the wet vent, the two LAVs are the most upstream fixture, aren't they?

@@richardwuttunee9355 You can tie any vent together as long as it is above the flood level rim of the fixtures they are serving.
vent minimum size must not be less than half of largest horizontal, if 4 inch all vents have to be 2 inch either way
Please give me the code reference for that.
