This is extremely helpful! My wife and I are turning our first floor closet into a half bathroom but we just failed our plumbing inspection because we used the wrong fitting - should have used a wye instead of a ty. It all makes sense now after watching this. Thank you!!
I appreciate that you've covered most all the different fittings. I was concerned about the sweeping wyes and the siphon effect. Something that might be helpful on your diagrams is to show the viewing direction of the fitting installed drawings on the stick diagrams.
I believe you got confused a bit, although in theory yes you do want a slope on those branches leading up to the wye T, when you add an off set like that 45 you are exceeding the fittings purpose. In other words if you had a branch glued directly to a wye you could only slope a certain amount in order to glue them together without causing a leak, therefore the wye fitting could be slightly sloped but not enough to break the plane. Picture a combo wye, if you would have used one it is still limited to how much you could rotate it. Maybe you meant to do it maybe you didn't but you created your own combo wye, that was really the problem. I hope this made sense. And for those saying that it would siphon the traps, it's really more about waste water running faster than the actual waste and the branch not being properly washed.
Great video Edward! Im working on writing my CFQ and this definetly helps with the visuals! Subscribed. Which building code do you refer too in your videos? Im currently working under the OBC
14:41 you mention two 45° need to be separated by 12" of pipe in order to make a 90° horizontal bend. Does the distance requirement between the two 45° change depending on pipe diameter? Or is it 12" for any dia pipe.
Is it proper to lay the gravel bed first, then the pipes, or to lay the pipes first on earth, then the gravel bed, before pouring concrete for SOG/Flooring? BTW, thanks for the video. I learned a lot from it. More power to you, Sir.

Thank you!!!! I wasn't sure whether to buy a T or a sanitary T. You answered my question!

This video is worth a lot of money.

Excellent video. Thank you
I wish they had videos of people going over plumbing code
Great video Edward! Im working on writing my CFQ and this definetly helps with the visuals! Subscribed. Which building code do you refer too in your videos? Im currently working under the OBC
The OBC, keep in mind there are changes coming soon. Most likely in January 2025z
@@edwardlogan5428 Can't be too much! I just showed my class your videos for additional help!
God bless you, sir. Just a perfect video of the exact info I 2as looking for!
I gotta check the code
A double wye on its back is better than a double combo
And i know double combos cannot be used vertically
Thank you so much for sharing. This video is so helpful. I am wondering if you have online courses for teaching new students in cananda ?
Very well explained.
Nice 👍
Everything has a science to it..
Cud i use a double y upside for venting?

I wondered the same thing.
Can't imagine on a 2" pipe there needs to be 12 inches.
on a very very large scale application, how do you plumb for far distances given the supposed curve of the earth??
Shouldn't matter since the force of gravity curves with the Earth's surface if that makes sense
@@domiinstallatie absolutely not
There is no curve!
@@charging7 ah yes, flat earth :P
I appreciate this sir!!
There’s a San tee,eye or combo but no such thing as a tee wye. You’re combining two separate terms.
Is it proper to lay the gravel bed first, then the pipes, or to lay the pipes first on earth, then the gravel bed, before pouring concrete for SOG/Flooring?
BTW, thanks for the video. I learned a lot from it. More power to you, Sir.
Thank you.

Is this IPC OR UPC?
confusing explanation vs. his "drawing"
