Abstract: A pneumatic test plug for clean-out tees and a method of testing a pipeline are disclosed. The pneumatic test plug includes a cap and a bladder. The cap has an inflation inlet and a testing fluid inlet. The testing fluid inlet provides a conduit for a testing fluid. The testing fluid may be a liquid or a gas. The bladder is in fluid connection with the inflation inlet. The bladder has an open end and a closed end. The open end receives air from the inflation inlet. The closed end is opposite the open end. The testing fluid inlet provides testing fluid through the cap and outside of the bladder. The inflation inlet provides a passageway to the bladder.

Abstract: The present invention relates to an air admittance valve (AAV) that operates automatically at low pressures to selectively open and close an air passageway between an inlet and an outlet. The AAV comprises a valve body having a centrally disposed, intemal valve chamber in communication with the ambient environment, and having a valve seat. The AAV includes a sealing member having a flexible diaphragm that is fastened to a support ring, the ring defining one or more lugs on an outer periphery thereof. The AAV further includes a cap member within which the sealing member may be disposed, such that the one or more lugs may interact with an interior surface of the cap. The sealing member may selectively seal or unseal from the valve seat in response to pressure differentials between the inlet and the outlet.
