Abstract:
A closure plug assembly for the pressure testing of liquid drain and vent plumbing systems including a T or Y test section with a test opening comprises a cap sub-assembly, sealing means for releasably securing the cap sub-assembly across the test opening, and a plug such as an inflatable bulb or plate removably insertable in the plumbing system adjacent the test opening for test-damming the flow of liquid upstream therefrom. Link means is connected to the plug for removing the same at the conclusion of the test operation. A valved port in the cap is used for filling the plumbing system with test liquid under pressure during a testing operation.
