ABSTRACT:
An improved testing device for testing a drainage or plumbing system for vertical piping is provided which allows the tester to determine which particular floor is being currently checked for leaks at any time during the test. The testing device includes a tee disposed in fluid tight series communication between a drainage system and drain. A controller means is included which utilizes a ball valve to prevent water spillage during removal of the testing device when testing the drainage system for leaks. A ball valve actuator facilitates actuation of the ball valve. A closure plug assembly is provided which includes multiple ports adapted to accommodate a valve stem of the controller means and a fillgauge apparatus. A fluid elevation gauge provides tester with a visual readout of water elevational levels. A lightweight container is provided to store the testing device to facilitate transportability.
