Abstract:
A connector assembly for sealingly attaching an air admittance valve to a vent pipe end comprising:a) an air admittance valve body having a rigid bottom portion with an open truncated conical configuration having an exterior wall having a threaded intermediate area and a generally smooth bottom peripheral area; b) an elastomeric sealing gasket having an upper lip, an intermediate exterior retention area and a lower sealing ring portion, said sealing gasket having a tapered interior bore having threads in an intermediate area above said lower sealing portion and whereby the placement and turning of said rigid bottom portion of said valve body into said elastomeric sealing gasket causes said intermediate exterior retention area of said sealing gasket to engage and grip the interior of the vent pipe and said bottom peripheral area to expand and seal said lower sealing ring portion of said sealing gasket against the interior of the vent pipe to thereby secure and seal said air admittance valve in the vent pipe.
