IPEX PermOseal® DWV Air Admittance Valve, ABS Body
Allows air to enter the drainage system, while preventing sewer gases from escaping. The AAV only opens under negative pressure in the piping system, while remaining closed if there is positive or ambient air pressure - Eliminating the need for external venting.
