Sensitivity to pressure changes, combined with its ability
to consistently open and close, is what distinguishes the
Oatey® Sure-Vent® AAV from all others. Superior engineering
along with stringent quality standards ensure a lifetime of
Available in 6, 20, 160, and 500 DFU. An air admittance
valve’s ability to breathe is measured in Drainage Fixture
Units or DFUs. The higher the DFU rating on the valve, the
greater amount of air that can enter the DWV system. DFU
loads are assigned to plumbing fixtures dependent on the
volume rate of discharge, the duration of operation and
the time between operations. Common fixture load ratings
are shown in the table.
To ensure proper breathing capability, determine all
fixtures to be vented and calculate the total DFU load,
then select the appropriate Sure-Vent® for the application.
Each Oatey Sure-Vent® cap indicates its maximum DFU
rating — 6, 20, 160 and 500 DFUs.
Example: In a house with a laundry room and bathroom sharing a common wall, the DFU load
would total nine. Five for the bathroom, three for the washing machine and one for the laundry
tub. The 20 DFU Sure-Vent® is the right AAV for the job.Read more ›
I learned about this plumbing product by accident. When I asked for it at the local building supply store they didn't know what it was. Amazon to the rescue again.
I do know, though, that when we started getting some foul odors coming from the kitchen sink of our 7 1/2 year old house and those odors couldn't be stopped by any amount of cleaning, I decided to do some investigating under the sink. Before this, I didn't even realize that there was one of these air admittance valves under our sink, but there it was -- and that was the source of the odor.
This thing basically is a valve which opens to let air in when water runs down the drain and then closes when the water has stopped. You need it to close because it's on the downstream side of the P-trap, so if the valve wears out after tens of thousands of uses as mine did, you'll get sewer stench flowing back into your house -- yuck!
Once I'd pinpointed the source of the problem, it was an easy fix. I just made sure I was buying a replacement valve with the same thread size as the existing one so I could simply unscrew the old one and screw the new one in. Problem solved -- no more stench!!!!
I didn't use the supplied PVC pipe because I was simply replacing the valve itself, not doing a new installation.

Not sure how to tell if it's working. Installed this to help with slow drainage of an unvented kitchen sink. I have only seen slight improvement.Published 7 days ago by Tex75
This product does not let the drain go down fast. Actually it was not a lot faster than before it was installed. I thought this would be the answer, but it was not.Published 12 days ago by Nancy Wolfe
I installed the vent valve because I had no place to install a vent so when I learned about the Sure Vent I knew that it was the solution to my problem. Read morePublished 4 months ago by Ken

This AAV just flat out works. We had a drain vent issue after a remodel and every time the toilet flushed, the P trap would get cleared out on another fixture. Read morePublished 10 months ago by SK Wire

I placed this air admittance valve under a bathroom vanity. The suction from other bathroom fixtures was emptying the p-trap's water allowing occasional sewer gas to escape. Read morePublished 11 months ago by Joe Wildenberg
A great buy if you're looking for a low capacity (6 DFU) air admittance valve. Local stores only had sizes 20 DFU and higher, which are two-inch diameter PVC. Read morePublished 12 months ago by jpsfb
