Oatey Sure-Vent Air Admittance Valves
By eliminating the need for a branch vent, Oatey Sure-Vent Air Admittance Valves (AAVs) provide the ideal venting solution for island sinks, remote bathroom groups and remodel jobs. Sensitivity to pressure changes, combined with its ability to consistently open and close, is what distinguishes the Oatey Sure-Vent AAV from all others.
Why Use a Sure-Vent Air Admittance Valve?
Ensures Proper Drainage
Every fixture needs a trap and every trap needs a vent. To prevent sewer gases from being released in a home, a trap is required. A vent keeps the sewer and atmospheric pressures equalized allowing water to drain freely.
Eliminates Secondary Vent Pipes
Sure-Vent AAV's provide the ideal venting solution for island sinks, remote bathroom groups and remodeling jobs by eliminating the need to be connected directly into the stack vent.
More Economical
Sure-Vent AAV's are more economical than installing vent pipes in new construction because they reduce the added need for materials and labor.
Unmatched Performance
Zero Pressure
At zero pressure the Sure-Vent AAV is sealed, ready to react to pressure changes. The Sure-Vent AAV will not allow sewer gas to enter the structure.
Negative Pressure
When water is turned on, a pressure change of -0.01 psi (-0.25" H2O) will cause the Sure-Vent AAV to open, allowing airflow from the room through the protective screening, past the seal and into the DWV system as the arrows indicate. When the water is turned off and pressure equalized, the Sure-Vent AAV returns to the closed zero pressure position.
Positive Pressure
The Sure-Vent AAV seals at 0 psi and above indefinitely. The figure shows the Sure-Vent AAV in a sealed position blocking sewer gasses. When pressure subsides, the Sure-Vent AAV returns to the zero pressure position.

- Reviewed in Canada on October 13, 2024Verified PurchaseWorks great, but tricky to find the correct sized fittings for a sewer pipe.
- Reviewed in Canada on September 9, 2024Verified PurchaseI had used this to replace a cheaper vent.
the cheaper vent was only good as a home to spiders... LOL
I had a constant smell in the basement that is now gone.
Only issue is that you need plumbers tape to properly install this... so make sure you have a roll somewhere...
definitely recommend

5.0 out of 5 stars After several plumbing bills, we finally figured out the smell!
Verified PurchaseInstalled this in our business after several weeks of dealing with a sewer smell and wow it made such a difference. Not only was it ready for install but it was inexpensive and saved us so much money! No more expensive plumber visits. Definitely worth it.

5.0 out of 5 stars Works without any modification w/ 2" pipe, works with adapter w/ 1 1/2" pipe
Verified PurchaseThe threads on the actual automatic vent unit are 2" male.
The included ABS adapter has 2" female threads on one end and a 2" female slip joint on the other end.
If your vent pipe is 2", the included ABS adapter will glue directly on to your 2" ABS vent pipe.
If your vent pipe is 1 1/2" ABS, you will need to purchase an additional ABS adapter at your local home improvement store to reduce the diameter from 2" down to 1 1/2".
Installation is straight forward.
Make sure you use Teflon type tape on the threads of the automatic vent to completely seal off any sewer gasses.
I like that the automatic vent is threaded (not solvent welded) to allow for easy removal if the unit requires replacement in the future.
