- www.homebuildi... Visit our website for more helpful videos about plumbing, home building and building codes. I hope this will help anyone who was as confused as I was about vertical and horizontal plumbing drain and vent pipe connections. Yes, you can connect them at different angles than 90 or 180 degrees in some cases. Watch the video to learn more about your home drainage and plumbing vent systems.
Thank you very much for sharing a descriptive lesson as this.
You're very welcome!
I had a situation where the only place I could vent the toilet was from behind. It worked quite well, but I couldn't find anything written it the IPC, the UPC, or anywhere on the internet, which described this as being an option.
I'm glad to finally see it referenced somewhere!
because its not. you cant put a drain into the trap arm of the toilet. best case is to paralell the drain from the sink and tie it down stream of the vent inlet.
Glad to help.
Your videos are done so well thanks for so much information had to hit the subscribe button 🍻
Welcome aboard!
Thanks for the lesson.
You're welcome and thanks for watching.
In this example, can you run a horizontal from toilet to sink under the roof deck in order to reduce to just one roof penetration ?
Great video and explanation. Thanks 😊
Glad it was helpful!
In the last example, could the wet vent be 2 inch, from the 3 inch combo wye?
Thanks ,my question is if the stack is with in 6 ft of the fixtures do you need to vent them? Small bathroom
Every fixture needs a vent.
Do you have a good example for using 4 in. x 4 in. x 4 in. x 2 in. x 2 in. (Nibco 4870).
I imagine is it can combine lavatory, toilet and tub drain and give vertical vent at the same time.
I don't think so. You can check the plumbing section at our website, it might provide some other designs that will work.
is this for los angeles?
You will need to check with them, but it should work.
Hacked up by the plumber?? No way😊
Why not just use a San tee for the vent you don’t need the wye.
You can, but my thinking is always design pipes for snake cleaning tools, that's why I suggested the combo fitting.
Vertical i just can't see being a good thing.
Big tyrd flopping down into the pipe...
You cannot vent a toilet in the fashion (horizontally) you have shown at about 4:46 without that vent being a wet vent. With the system you are showing, the vent for the toilet cannot break to horizontal until it is 6” above the flood level of the toilet. In some cases where it is absolutely impossible to vent a toilet or other fixture vertically before reaching the flood level, an inspector may let you do it the way you have shown if you install a cleanout on the vent. But you made no mention of this and your animation does not show a cleanout. You just can’t do it this way without permission and a good reason.
You are correct . That is dry venting and ,in the event of a blockage , effluent and waste can get stuck in that horizontal branch with no wash out .
It can be configured that way if it has a lavy upstream washing it out . In that case it's a wet vent , as you said .
Also when horizontal branches are pitched at 1/4" per foot . fluids adhere to the inside of the pipe in a circular , scouring motion leaving the center hollow . Not filled halfway with fluid as this video shows.
