I AM READING A BOOK Regarding the ipc venting. The show a wet vent system. They show 2 bathtubs on a double wye Upstream. I thought you could only have 1 fixture upstream from the vent. DOES the double wye circumvent this rule. Allowing 2 fixtures.?
The new or latest Canadian National code book (2015) version has a small amendment to it under FIXTURES DRAINING INTO VENTS 2.5.4.5. c). This states that....the section of the vent pipe that acts as a wet vent is not less than 2 inches in size....This pertains to fixture units dumping into the wet portion of the circuit vent, which means that the video should say that the vertical red pipe (wet portion of circuit vent) above the cleanout should be BANGED UP A NOTCH to 2" instead of 1 1/2" which was previously good on the 2010 code book.
The downmost green pipe: Is it not the relief vent of the circuit vent. In the video, it says circuit vented branch. Could you elaborate a little bit. Thanks Fred. (Great video. I went through several times already)
You cannot wet vent a urinal, least not here in Michigan. Wet venting is for bathroom group fixtures only, which are : Toilets, Emergency floor drains, bidets, showers, tubs, and lavs which are actually individual or common vented, but extend from the wet vent.
The 2 lavs hydraulic load or fixture unit load are effecting the wet vent and are included in the load. What I meant is that the 2 lavs are not being wet vented, they are above the wet vent and are drawing air from the continuous vent above them.
if you are talking about the wet vent and or the circuit vented branch, the wet vent on the top half of the animation is 4", so it could be 1/8" , 1-100 or 1% min grade, and the circuit vented branch on the bottom half is 3", hence it could be at min grade 1:50, 1/4" per ft, or 2% grade.
@@notooshaby Hi Fred. Thanks a lot for taking time to reply my question. Ai the installation of a plumbing system, I am curious to know how do they achieve this vertical piping (risers, stacks, etc.) and the horizontal drains that are sloped usually. Is the fitting at the intersection is 91.193 degrees for 1:48 slope? Do we use an elbow of 88.807 degrees elbow at the upstream of the trap-arm of a p-trap (say 3" trap size) of a WC. How do we specify these fittings? Please help. (Note: I will be taking a series of plumbing training courses from BCIT here in Burnaby, BC.)
sorry, but why does the diagram indicate that the two lavs are NOT included in the wet vent load, but you clearly say there is 16 fu's (2x7 +lav+lav) affecting the wet vent. And could you you refer me to the clause that states those lavs shouldn't be included, thanks!
This is once again the 2010 Canadian National Plumbing Code......Plumbing codes in many different states in the US many differ from each other as well from Canada's National Code...
Man thank you so much , Iam from BC and your videos from 2012 are saving my a*** lol thx

7:13 That's pretty cool to know, I never realized that.
The 2 lavs hydraulic load or fixture unit load are effecting the wet vent and are included in the load. What I meant is that the 2 lavs are not being wet vented, they are above the wet vent and are drawing air from the continuous vent above them.
Fred: thanks for clarifying this is Canadian plumbing code.
I am new in plumbing. This is a great video. I have a question about the long blue pipe. Is it horizontal or at a slope (for example 1:48 (2%))?
if you are talking about the wet vent and or the circuit vented branch, the wet vent on the top half of the animation is 4", so it could be 1/8" , 1-100 or 1% min grade, and the circuit vented branch on the bottom half is 3", hence it could be at min grade 1:50, 1/4" per ft, or 2% grade.

So cool! S.A.I.T. represent!
2:30 wouldn't that be either a double fixture fitting or a double santeeinstead of a double wye-tee/combo?

man you are my hero :)
Can you do a island vent ? I heard there's a new method of doing it
Here is my video on island vents...latest method... ua-cam.com/video/ZiDAC0kQ3QI/v-deo.html
