The present invention is a sewage system isolation valve assembly designed to be installed between a sewage drainage line of a building and a sewage service line. In its initially closed position, the isolation valve assembly provides a closure means for closing and isolating the operating sewage system of the building, thereby permitting the drainage system of the building to be filled with water for testing purposes. Once the testing procedures are complete, a test shut-off baffle may be torn or detached from a gasket which is securely attached or secured within the sewer drainage system. The test shut-off baffle is removed from the isolation valve assembly by pulling on a removal means.
