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.
