Air Admittance Valve is installed where installation of a vent pipe is not an option such as in renovations or island sinks. It's often called a cheater vent.

It’s gotta be above the basket strainer. At least
I believe it should be installed higher than the bottom of the sink.
Yea correct
nice job
Nice but make it screw on and off for removal/ replacement of sink/taps
Great vid, would love to see more details on your stub out behind the abs, any vids on that?
What glue did you use?
Go above the high water line

Does this mean it *should* go above the countertop?
No
Above drain line should be fine
Must be above water line in sink.
How is that even possible? Also what is considered the water line? Top or bottom of the sink bowl?
For a sink, minimum 4” above the horizontal branch drain after the trap.
Could it be also installed for WC ventilation?
Will this take the place of an air gap in California
I see that your not afraid to take up all of the cabinet space 😂
What’s the other option in this scenario..?
you could have put the tee in for the trap up another 6 inches and the plumber should have put the drain pipe in the back corner of the cabinet
@@Andrico77and you could have used a basket strainer in the sink that didn't drop so far right along with getting the 1st drop pipe shorter
And the plumber should have put In a positive vent in so you wouldn't have needed the studder vent in the 1st place if possible
How do you stop the backflow of foul odor?
It’s an air admittance valve. It’s like when you put your finger on a straw in a cup of water, it creates a vacuum and is air locked, releasing your finger allows the water to flow. This valve allows air to enter, but not sewer gas to escape.
Thank check valve for air
Look at his voice. 😮
do you really need to pull put the measuring tape for this?
You felt to. Moment on that…
Question. I have a vent like this under my kitchen sink and water is coming out the top of it when i drain my sink. Is it clogged or something???
Clogged or installed wrong, probably
Most likely clogged
My shower has a bad smell coming from the drain, only when the water is running. I think it's because my bathroom lacks ventilation in the drainage. Can the problem in the shower be solved with one of these valves?
most probably
Is your house on the older side? Maybe it was also a remodel done poorly and wrong. I am going to say it’s most probably due to the lack of a p trap. A p trap holds water which prevents the sewer gas from coming up but allows water to drain when you use the fixture. Maybe who ever installed it didn’t know what they were doing or sometimes older houses lack it. You would have to either replumb the drain system if you have access to below or take your shower apart. I would call a professional in your area to make sure this is the problem as I cannot see what you have currently.
In the video the guy has a p trap, but this vent he is installing is what you have to do to all plumbing drains within 5 feet of the drain to allow for air to enter to remove negative pressure. It allows for the water to drain more efficiently without the gargles.
Hope this helps!
thanks! @@amaljose7088
In my old azz house they ran the vent stack into an abandoned chimney, a way to avoid climbing on the roof. Crows like to drop crap down it all the time so eventually it will clog as happens around here. When it happens I'm just going to make use of these fancy valves, as I'm not climbing on that roof either.
Lack of vent and the p trap water gets sucked out I believe. So my guess is if it just started stinking your vent got messed up because without a trap I think it would pretty much always have stunk.
Check with your local blah blah. They are not permitted in my area in CA
I am in San Diego, moved into an apartment and I found out there is one of these very similar in the closet in the bedroom and I am getting weird smells especially at night, I'm almost sure it's coming from there. I cannot unscrew it, I was thinking if I couldI would pour water down there and that might fix it, that works in Montreal with the type of plumbing we have but it's not like that, there is not cap on it.
Can anyone please tell me the name of that white thing?
AAV = air admittance valve. Studder brand or Oatley
Hand condoms.
Genuine question here… How does that not stink from sewer gasses coming up?
Spring loaded check valve in the air emit valve. One way valve
If it's mechanical it's going to fail and the best part is 99% of the kitchen sinks only need it because code says so on account of that 1%
@@George-yd7cxI'm moving a kitchen sink a couple feet basically due to new layout; my current kitchen sink isn't separately vented (the house has one vent at the main stack going out the chimney) and works totally fine. I was thinking I would do one of these valves but am debating since I don't have one now. It is going to be a longer run to the stack than it is now, like 10 feet more. Should I skip the valve? I'm not getting an inspection.
@kw6713a i will usually put a cap on where the studder vent goes and if it ends up needing it cut the cap off and put 1 on and you can use the cap for a cleanout if necessary
@@George-yd7cx I dig it my friend, thanks much.
Would be stink
It's also called a stupid vent for those who don't know how to run a proper vent during rough in
How would you run the vent on an island sink?
Vent us to low
Unless u live in a state that actually has codes and doesn’t let any idiot do plumbing 😂
