Abstract
A waste and overflow system for a bathtub includes an overflow conduit having a threaded end and an overflow cap threaded at one end extending through the overflow opening in the bathtub into threaded engagement with the threaded end of the conduit. The other end of the overflow cap has a test cap portion removably connected thereto for closing off an overflow passage through the overflow cap during pressure testing of the system. The test cap portion is removable from the other end of the overflow cap upon completion of the system pressure test to open up the overflow passage through the overflow cap.
