Dumb ass the main reason is that sewer gasses will flow out of an open sewer pipe. The methane that vents out of a pipe could even fill the room and create a possible explosion.
That kitchen vent is called a loop vent
How do you replace a vent pipe when it cracks?
1:02 If you flush a toilet, wouldn't that toilet be vented so that water wouldn't be syphoned out of the p-trap of the lav? And, is it permitted to join PVC to ABS as in the image?
Thanks for the video. Do you think that an air admittance vent should be used on a sink that has an under sink garbage disposer?
great video, learned exactly what I was looking for after coming come from a plumbing meeting
Thank you so much I found this garbage in my house and I’m going to go get a valve immediately
Thank you so much, you have actually answered the question I've been searching for all over YouTube.
I've had one for years where I replaced an S-trap and it works great! You have to make it accessible though in case they need replacement, but it's far better than nothing!
I had a open pipe like that in my wall I changed it out with a aav.
