- Air admittance valves, also called cheater valves or mechanical vents are mechanical devices that take the place of plumbing vents. Structure Tech, your Minnesota home inspection company puts air admittance valves to the test in this video. Air admittance valves are inexpensive, they work, they can reduce the number of plumbing vent penetrations at the roof, they won't get blocked by frost, they're listed and approved by several listing agencies, and they cost way less to install than a plumbing vent.
Oh, and they're not legal here in Minnesota.

I appreciate the time you took to explain the Air admittance check valves. More importantly, it clearly demonstrates the legacy of continued overreach by bureaucratic or preferential regulations. People who develop these regulations do so to align their careers or to justify their existence. Which naturally leads to volumes and volumes of regs stacking up decade upon decade. One day, a new breed of authors will realize that they can make history by reviewing and deleting the outdated regs.
He's in Minnesota. You can thank democrat voting labor unions for the regs. Gatekeepers to prevent private entrepreneurship. All unions and HOA's suck donkey balls and are anti capitalists
Telling a home inspector that you know better than the building code is a really special kind of special.
Your bloopers - I had tears in my eyes from laughing. I can SO relate. By the way, excellent home experiments on the AAVs. You convinced me they’d be ok to use in a new garage deep sink I’m installing. Thanks.
Your comment made me watch the bloopers I'm dying
Glad I stayed for the bloopers!
me too! oh man hysterical
No doubt. I was on my deck watching and cracking up so loud the neighbors came out. Loved it! Oh.....very informative video as well. Heading out now to purchase one!!
Yy see do dee dee by
I realize that I'm 3 years late to this video, TOP 3 of the most informative videos I've seen about plumbing.
Those bloopers were great. Alot of UA-camrs would never show that stuff. Good laugh. Thank you.
This video should have a million views, excellent information and you, sir, have a real sense of humor for the bloopers! My wife thinks I'm crazy and I about choked laughing! Thank you.
Loved the Bloopers. This should go viral. Thanks for sharing. Had no idea AAV were needed.
Greatest bloopers ever! Thanks for being a good sport and sharing those with us!
I just purchased an old remodeled house in north carolina, and every drain has one of these valves. I've never seen them before. Thank you for the great info and tests.
Thank for you time and effort and your strength of ego to share your bloopers BRILLIANT TRULY BRILLIANT. THANKS AGAIN
Your honesty in including the bloopers got you a subscriber! You answered a bunch of questions I had, made me laugh and cured my headache. It was the least I could do in return.
The ending outtakes killed me!! Informative and funny. Thanks for taking the time to test and explain =D
I love this video. The bloopers at the end are a must-see. Very informative video. It answered my question about cheater vents.
Thanks for spending the time and money to provide this content. I've been using these for years. Some inspectors approve and some don't. Gotta love the inspection process!
Love the bloopers! Lucky you did not loose an eye. Excellent video and thanks for doing all the tests. Feel much more comfortable installing one of these now.
Lol, lol, lol 😂 That was a good video explaining the air admittance valve, and the bloopers at the end were great! I needed that laugh, and I am glad that you included them and that you weren't hurt!! I need to install one of these under my sink because when the washer water drains, there is a mighty gurgle in the kitchen sink! I will clean it out well first because I think there is probably a partial clog, too. I'm a 72 year old widow who always worked at office jobs but with the help of several UA-cam videos, I think I can do this!! We shall soon find out.😊
That was hilarious!!! Thanks for alleviating my skepticism on using an AAV.
So appreciative for the informative demos, Reuben.
Appreciative also that you didn't tear, spindle, or mutilate yourself along the way! Stand up comedy is evidently in your future. Cheers!
The bloopers were absolutely hilarious! I could totally see that all happening to me! 😆
Exactly what I was for, especially the clog test with head pressure to simulate the vent below the sink brim. Perfect.
Its a mechanical device with a type of valve & spring regardless it can fail. I don't want sewer smells in my house ever. I'll go for the standard vent that passes through the roofing to outside. Nice video & its good to see new products.
I just recently replaced my AAV for my double compartment kitchen sink because it didn't seem to be getting enough air in the system to drain thus when draining a some what soapy sink full, I would get alot of soapy water backing up into the other sink. Some water is expected to back into the other sink but mine was more than it should. Then even after that when draining water down the sink I previously drained all that soapy water, suds would back into the opposing sink excessively.
Initially I thought I had a partial blockage snaked the line but still had this issue.
In the end I replaced the AAV (oately) read on the it that it was rated for 9 DFU'S (a kitchen sink is 1.5 DFU'S) The one I got from home Depot was rated for 160 on a branch and 24 on a stack. They seemed to have improved the design and made it larger.
Now I do not have the issue of excessive suds backing up.
Just wanted to pass this on if anyone else was having this issue and couldn't figure it out.
These are designed to stay closed until a positive pressure is applied.
Venting systems purpose are to "maintain atmospheric pressure" in a plumbing system.
Thanks for the interesting video!
That's one aspect I was actually looking to be compared between the different brands of AAVs. How much vacuum will the valves allow to develop before they open and allow venting to occur.
This would determine their effectiveness as a vent, and kind of the opposite side of their ability to maintain a seal under positive pressure.
In my case I want to make sure it doesn't allow a vacuum to develop because my sink drain isn't draining well due to the piping configuration, and correcting it would be too big a deal at this point, having to break open the wall behind cabinets.
I wanted to see which one actually offered the least amount of restriction, with the positive pressure hold as the secondary function, even if that's normally the most important function.
It would need to be tested with a manometer and a vacuum pump, to see how many inches of water it would develop with the valve installed.
OMFG, glad you were not hurt. Those outtakes were hysterical. Thanks for the vid. I was going to create a new vertical vent for a sink in the basement, but now I know, I don't have to.
I have a sewage smell under my sink i'm chasing. I'm hoping a failed admittance valve is the culprit. Thanks for the video
Better than the last 10 movies I've watched, loved it!!!
"Next week's episode will demonstrate how to patch a 3" hole in the drywall in your ceiling." after watching the blooper reel. Thanks for sharing!
Your knowledge is much appreciated, even the unplanned and messy bits do help my understanding of that system, like.
Good video thanks
GREAT BLOOPERS 🤪
Now I'm going out to my garage to make an Air Cannon!
This is just exactly how it always goes out in the real world! There used to be a show on HGTV called Real Reno’s and they always showed the goof ups cause that is the way it really goes! Great video !
Didn’t find what I was looking for, but sure am glad I stayed for the bloopers!
I’m a female and I had to see if these air admittance valves work because I’m installing one in my trailer home and this was the best video I’ve seen on UA-cam all year long I don’t care what kind of video it was this plumbing video topped it hands-down you made this awesome and thanks for the bloopers at the end!!!🤣
I am a building surveyor in the UK - we use them everywhere especially on high rise new build flats. When they fail or one has been fitted incorrectly you can tell because the resident complains of a strong sewage smell.
debstar2005 I need your help. I live on the ground floor in a 5 storey block of flats and have the very problem you describe. can I contact you please. Thanks
Surely not for a standard House...I get it for flat s but not a House.
If they are fitted properly and in the right place they are a problem solver. Great video.
You made me feel better about my plumber putting these in our new build.
Plus the bloopers were priceless. "That was loud..." :) :) :)
An AAV is supposed to be installed above the flood line of whatever it is protecting. So that made your test when the AAV was below that sink full of water even more impressive.
Thank you! I enjoyed your analysis and experiments and then had a wonderful laugh from the bloopers! Awesome!
Thank you for sharing your bloopers!! Keeps us from making mistakes. Appreciate that. 👍
Omg!! I absolutely LOVE that you included the mishaps. 😆 I don't feel like I'm the only one now! That was great! I lol'd for real.
Great info; I'm getting one. The bloopers have me in stitches. Wear your safety glasses kids.
Thankyou for testing these and showing they work. I must say I enjoyed watching as your quite a handsome man !!! This made this test much more enjoyable to watch!!
Very informative, and you may have missed your calling as a comedy film director/actor!
I am a DIY and always trying to learn, great video. THANK YOU!!! I must admit today wasn't the best of days but the bloopers did put a smile on my face, for that I sincerely Thank you again..
I came here to learn about AAVs, didn't know there would be legitimate laughs at the end. Good video.
Very informative Im looking at adding an outside Slop sink and want minimal disturbance to my Stucco wall when i tap into the bathtub drain inside the wall. Extra precaution. Bloopers were Great!
Love the bloopers. Glad you didnt get hurt.
Thank you for taking the time to educate us on these products.
THE BLOOPERS 😂
Great info,outtakes were hilarious, pretty much me, anytime i attempt to do something! Thanks for the video!
You did it! Made learning about Air Admittance Valves interesting and funny. Not an easy task.
Thank you for the video. Excellent info but truly loved the bloopers. Nice when you can laugh at yourself
Geez dude, the bloopers lol. When you took a hit off that thing was hilarious. I'm not supposed to be laughing this hard this at work.
and thanks for the info
I never comment on videos but this was amazing 😆 I’ve been watching videos to teach myself how to plumb my bathroom and this was both educational and hilarious so thank you for the laughs!
I passed inspection in MN with using the air admittance valve for a shower drain
oh man these bloopers gave me a good laugh. love the tests and great video all around ahaha. cheers
This guy going to blow his face off at least he did not glue it all together and let it cure or it might have exploded on him. When he hooked it up to the compressor I was really caught off guard and caught a good laugh thanks man!
Bloopers.....the best. Great video. Thanks for not being a cheesy home inspector
Excellent demonstration! Just one concern, if sewage does back up as you demonstrated, but it's gunk and not clear water, I suppose the gunk would cause the AAV to fail in the future. And, have you thought about making a video on how to use an AAV with an air compressor as a home defense weapon??
I loved the information in the video, but literally was laughing so hard I cried during your bloopers! Thanks for sharing it all!!!
Great video, and thanks so much for all the information you share. Your podcast is great! And thank you for the outtakes! Needed that laugh!
Thanks so much for this video. I'm putting in a new bath, and shower where none previously existed and I have a slate roof I really didn't want to have my plumber cutting into so, you just put my mind at ease about using one of those units. Just wondering if they will need to be replaced once in a while and if so how often, thanks.
Haha this was my informative and very entertaining!! Hahah thank you for including the ending. 10 psi is a lot of pressure.
Thanks so much!! We moved into a new to us home and all the drains go into the floor!! So it’s good to know these things are safe to use.
Man I haven’t laughed this hard in a while thanks for the test I now have more confidence using these in my house. Also thanks for the side stitches
Thanks for the video. I recently bought a house in TN and I have S traps under all my sinks since it was built before TN had building codes. I have vents pipes that terminate in my attic and occasional get sewer gases in my garage floor drain. Now I at least have a solution code or no code.
Excellent review and "edited" testing. Glad to know these things actually work well.
That said, thoroughly enjoyed the bloopers....you need to meet my good friend "Stoopie" who helps me do all of my projects.
Informative video. Thanks for the sewage leak test. That's what I have been looking for.
That was fun to watch. Thanks for the bloopers
Great video, informative and the bloopers were great!
good video! STAY for the bloopers at the end
I am not a plumber but I do have these in my home (installed them myself)
as I understand it there is one (1) concern about the reliability of these units, and that is that since these are mechanical valves they may become stuck open. This can lead to two (2) bad situations
first situation: sewer gas venting into your house
second situation: IF the vent is located BELOW the max water line height of the sink it's venting and IF there is blockage in the drain line and IF the AAV is stuck open then there is the possibility of waste water flowing out of the AAV.
For this reason, when these are allowed by code, they are supposed to be installed six (6) inches above the highest water level of the associated fixture.
I have had mine for nearly 30 years, they are not above associated fixtures (I did not know back then what I know now) I have had no problems what so ever from them.
My AAV is stuck open. That’s why I looked up this information. Can they be repaired or do I need to buy a new one? It smells like sewer in our kitchen and my wife ain’t happy about it.
@@danjabs4135
Just replace it
Thank you. I appreciate you showing the out takes. That was funny. We've all done things like that before. LOL!
Thanks so much for the bloopers! I was laughing out loud. You could have a viral video on your hands with this edited to have those in the main flow.
Thank you so much for the video! Very insightful!
😄 liked the informative first part of the video, really loved the blooper stuff. 👍
Great video, even greater bloopers 👍😜🤓 great job 👍
Those valves are used in rv campers so that might be the reason you see them on the shelves in Minnesota. Though depending on the specific text of the building code certain homes built during a time frame could be allowed to use those valves.
Super device. I am one that likes to see the nitty gritty, along with the smooth sailing. Obviously had the pressure set to high on your compressor in the bloopers lol.
Well obviously your nitty gritty is malfunctioning because an AAV is a sub par device. The only use it has in an old non vented house where the fixture keep sucking the traps dry. It does nothing to help draining.
@@1CornHolio they are used in most mobile homes because the state doesn't have any jurisdiction over them. Say, my state which is Kentucky has no jurisdiction over mobile homes and you do not require a permit to do plumbing work on one, except the water service and sewer
Great thing you didn’t point it into your face. Thanks for the info
Thank you for the info. Loved the bloopers!! 🤣🤣
Thanks for the information and the bloopers!
Great how to bud, you may have saved me from a torturous vent installation!👍
Very informative and useful. Loved the out takes. Thanks a lot!!
Thank you so much. You answered my question about water backing up and gave me a bunch of laughs too.
i started crying of laughter when he hooked the compressor up at 8:10
8:45 was waaaay better!!!
Fantastic finish! And great Info!
I appreciate your scientific method employment therein. Utmost blessings!
We’ve got one of these on my kitchen sink. The house was renovated and I guess the contractors didn’t want to connect the kitchen sink to the main vent line and just put a stand pipe with one of these on top under the sink. We seriously have to replace it every 6 months or so because it starts to malfunction after a while and gurgles and makes the sink drain slow.
Have you tried to run a snake down the stand pipe and down your trap? The 2nd floor of my house was built out in 2012 and the original AAV that was installed then is still working fine.
@@JesseKlaus as it turns out the sink drain pipe under the house was metal and old as hell. We had it replaced with PVC and it’s been going strong ever since. When the plumber cut the old pipe out he got me to hold one end and he held the other and you couldn’t see light through it from the years of corrosion. The plumbers that snaked it every time just punched small holes in it enough to drain and it would start to close back up after a couple months.
Great video! Love the bloopers section. My video would've been 9:00 of bloopers and 0:26 of good footage. 🤣
good info anf great bloopers. a real man can laugh at himself.
Interesting tests. I have used one of these valves before on an upstairs bathroom sink and it worked fine. With it being mounted below the sink level though your test makes me wonder if it would leak in that scenario (pipe clogged) if someone tried plunging the sink drain.
Seems like that would get it to leak?
Plumbing code here in the UK specifies that they should always be installed at least 200mm higher than the highest drain on the pipework. That avoids the possibility of water backing up and leaking through a faulty valve as it will back up into the sink/bath/toilet first.
THANKS SO MUCH!!!
You explain thing very well and the help is greatly appreciated
The bloopers were awesome
Thanks for the video. Maybe this has been answered already. But let’s say you have a clogged drain and you use a plunger! Would the pumping of it cause the sewage to come out of the vent?
loved the ending!!!!!!
Thanks everything I needed to know and more especially the blooper reel
Hit that wash tub with a plunger and do it like a frustrated home owner and don't be gentle. Let see if it leaks. OMG LMAO it blew up. LOL
Loved the bloopers
Thanks for the video and adding the laughs at the end.
Oh my goodness! That was the best laugh I’ve had all day. The bloopers, that is. Otherwise informative.
This was fun with morning coffee.
Almost had coffee coming out of my nose🤣🤣🤣
These things work great. I installed the two I have used above the level of the sink just in case of a backup and they leak.
I did bury them in the wall however. I have no idea if that's legal or if the use of them in my area is legal.
It's my house, so I don't care. I know it's safe and functional.
After living in my house for 4 years it started leaking sewage gas in my bathroom, come to find out there is no escape coming thru my roof. Trying to educate myself on how to fix it! Hopefully this works!
I'm doing a DIY kitchen sink and just heard about these. I was looking into adding one to help my sink drain a little faster, but looking into whether they're allowed in my city is coming up with 15 year old forum posts about the possibility they might be banned or limited. The reason being they have about a 2% failure rate over the last ten years and very few people like sewer gas inside their home.
For my purposes the sink does drain well enough and is vented where it needs to be. I don't want to risk the failure for a slightly faster kitchen drain so I'm going to skip it.
