Abstract:
1. A plumbing test plug for use with a threaded test plug inspection portal of a plumbing system comprising: a) a threaded test plug sized and adapted to removably screw into and form a water tight seal with the test plug inspection portal, including raised attachment structure on the surface of the test plug for grasping by a tool to aid in screwing in the test plug, and b) a rotating coupling with rotating first and second ends sealed to and passing through the test plug and attachment structure to expose the rotating ends, with a first end secured outside the plumbing system when the test plug covers the inspection portal adapted to removably attach to an air hose coupling associated with a selectively activated pressurized air source, and an inside second end adapted to attach to a test air ball hose, which prevents the test plug from twisting the hoses when the test plug is screwed into and removed from the test plug inspection portal.
