For those who dont know, there are 2 types, Sealed and not sealed. The one pictured in the video is a free flowing open vent. The sealed ones are typically black and have a rubber seal helded closed by a spring, which are one way valves and allow air to be sucked in as needed, but doesn't let air out. The sealed type can go bad, because they can get stuck closed, not allowing air in or out. Where are these typically located when put in a wall? Behind a shower or behind a toilet? I typically see them under a sink but I have a friend who had someone install some permanently behind a wall and they are having issues now. My other question is, how many are required for a 2 bathroom ventless house, meaning a house with No plumbing pipe roof vents? My assumption is there should be one at every location that has a drain, one per bathroom and one per kitchen.

She forgot to mention not to cover with walls completely. You have cut out a rectangle next to it and put an AC vent cover over it so that it can be checked and repaired if needed and get sufficient Air Supply

I'll save your ears and your time; its a one way valve so you dont need to run the vent through the roof.

My question is is the spring supposed to be stuck up or stuck down when you install it cuz my old ones all of them the spring is up and I just went to the store and got one in the spring is down my supposed to adjust it so the spring is up

Hi do I need to vent the pipe outside the basement through the wall? My plumber says just to leave it open inside the basement but I’m afraid of smells?

Lol He looks like the bold version of the guy in the wheel chair from Scary Movie 2.

Great video my friend, very informative, Thank you for sharing, keep safe

the studor ones are AWSOME! the cheap ones have a spring and fail, but these are thr RIGHT way

hello.... can i use this vent for four storey house?where will i put it?

Can you add this to a basement bathroom that is very difficult to get at the vent to the roof?

So that one is enclosed in the wall?? I would be concerned it would quit working at some point and cause problems.

How many vents are required with a toilet sink and shower and where are they located?

Yes, air admittance valves need watching. They usually fail within about 5 years plus or minus. Find out if your municipality permits them as some do not.

Yes, an air admittance valve is wonderful, and...they unfortunately fail. Make sure the plumber installs an attractive access door so that a new one can be installed.

Hi there , is this something that a inspector will aprove?

Thanks man. Good video.

Problem I see if you block the vent with drywall you may potentially create a vacuum that can make the cheater fail they are ment to in locations where air is abundant

Great video good info

Cane I use this with a macerating toilet system?

Good video thank you.

Ok great but can you did t discuss where it is. Is it connected on the toilet. Is it in the wall to be covered with drywall. Does it still get air if inside the closed wall??

In many states, AAVs are not legal on sumps or sewer ejectors in basements. Keep that in mind.

I would not hide it in the wall though, I would have exposed under the sink...it will wear out and need changing...

Fairly informative. Felt like someone was shoving railroad spikes in my ears the whole time, though.

What if the spring fails I'd run the pipe outside the back of the house I don't want nothing in my roof that I spend thousands of dollars on

Where can i buy one?

Sounds like a good idea but what happens when the check valve fails? Failed closed would be OK. Open or leaky would not.

Like others said, *do not install this inside a wall*! Underneath the sink is a common location.

Jesus christ man, your God damned voice can summon the dead!

Thanks for your info.

the instruction for installing this air vent is to be accessible for possible maintenance. it needs to be visible. it is wrong to put it between the studs suggesting being hidden later by walls.

If the pipes back up will this stop water from coming out or just air?

Spring is in the automatic air vent which is no longer approved, the air admittance valve has no spring.

If you use this in a wall, needs to have a panel. Also I would drill a inch hole on the top of the stud into the attic for it to get air. If you put in wall it will not have anyway to get air it needs and future home buyers wont even know its in there. Also buy a real valve something like a magic vent dont use knock off valves.

I’m planning on rutting my vent pipe that goes through the middle of what will be my daughters room in the attic. Cut and seal pipe from roofline then put this vent in the floor joists. The joist runs all along the house and out to my porch so it will get the air it needs I think.

I bet they told you, makes sense to not put this behind a wall especially if they need replacing, what a nightmare and what sleepless nights I'd have wondering if my toilet is burping stink in my walls... thanks for sharing

Thanks David Cross

take a shot every time he said "basically",.....drunk before end of video

These valves will break down and fail over time, so it's a bad idea to have it concealed in a wall, where sewer gas could leak out of it and make it difficult to find when trying to get rid of the smell. Best to just reroute that pipe to the right of that stud by drilling through it and go straight up and out the roof. Definitely a better, more permanent solution.

How dependable are these? Longevity?

No se me olvido traete los tuyos

Could you please tell me where we can get cheater vint

The question is: How long it stays in good conditions? Do they get stuck?

Basically it works! 😁☝🏻

Do not install this behind the wall, if it's defective how can to replace it in the future. Only install this behind the sink or anywhere accessible in the future.

Mine are under the vanity/ bathrooms and under the kitchen sinks. Let me tell you after 5 , 6 years plan on replacing them. We had guests for about a week . Using the extra bathroom and shower. We found that if the shower was not used in the extra bath room for over 30 days, the trap went dry, and gas would back up no matter whether a cheater vent or not.

Is that legal in ohio

I think I saw an installation under and behind a toilet in a European bathroom.

Kitchen islands are piped with an island vent… not a pro vent these are illegal where I live.

So basically what you're sayin is, its a pretty BASIC systems

Can you use this as a vent for my toilet?

Heeyyyyy everybodyyyyyyyy!!!!

So, basically, this is basically a really bad idea, like basically fix-a-flat in a car tile. It's basically a band-aid and basically a major problem waiting to basically happen, basically, so...

Cheating vents. How will the cheating vent get air if your going to wall that area with drywall or plywood. Would there be sufficient air? The wall is basically basically sealed. Also you repeat repeat too much much.

Alternative is if you are adding new sinks, bathtubs, toilets, just simply tear the wall open, tear the ceiling apart, cut a hole in your roof, do not put a island sink in, and do not go over the speed limit. I saw on a cruise ship, every wash machine had their own AAV. Someone should make them cut holes & put pipe thru every floor of the ship.

Cocaine is a hell of a drug.

Nice of him to let his wife narrate the video .

Why is he screaming?

Hi, In NYC this is a tremendous violation by the building's Department. Big NO NO. Try going the extra mile and do it right the first time all the time. Thank you

Cheater valve has to be above the fixture's flood line, so no good for kitchen island sink

Just to let you know it’s called a studor vent

First, a AAV is a gravity controlled device. No springs are used in the operation of the device. Second, you need to box the valve and allow it to pull air from the room. You can not simply place it in a wall between two studs.

There are no springs it’s done by gravity

Dude, it's called a Studor vent, not a Cheater vent.

Ok badger...

Plumbing system ????? How about DRAIN VENT SYSTEM....... Plumbing system can refer to any part of the plumbing.

These vents are not up to code in all the States, please check with your local jurisdiction. Also, this installation is incorrect. You CAN'T hide an AAV behind walls due to possible (expected) valve failure which will cause sewer gasses to leak into the home. You MUST be able to see, hear and replace the valve at a glance. That's why they are usually installed under the sink. Don't follow this video's advice.

They should be illegal. They are supposed to be changed out on occasion and when they are buried in walls and such you cant find them when they fail filling the house full of stink and gas. Last one I found in a drop ceiling that failed and filled the space with methane. All it was waiting for was a spark from the overhead lights. The one in the video will be buried behind sheetrock on both sides and the homeowners will never know about it and think something died in their walls when it fails.

Voice lessons plz

Basically Basically Basically Basically Basically Basically Basically Basically Basically

You are a plumbing god I am in awe of your immense knowledge! You should be the head of your state's plumbing board!

aka cheater vent. its called a air admittance vent

Oof that voice

You can still bring it outside I think. If it get stuck, drill a hole.

Gilbert gottfried?

There is no “spring”

Your voice is like nails on a chalkboard!

What's all this spring talk????

Ghetto, I know the inspection did not pass with this Mickey Mouse shit!! Am I watching the Disney channel.

Horrible video. You're making people think that this a good substitute for a traditional vent. Some fixtures don't work well with this.

Why are you yelling

very poor explanation of your topic. glad you're not plumbing in my home. you should know that they cannot be concealed, they have to be accesible. as well, if you don;t know how to vent an island sink, maybe you should watch some videos instead of producing them, AAV are supposed to be above flood level rim so why do you suggest using one ?
