System for pressure testing waste and overflow from a bathtub

A system for temporarily sealing bathtub overflow and waste water plumbing to provide for pressurized testing to locate leaks wherein the bathtub has waste water and overflow apertures formed therein having a first diameter, the system comprising:

• a female coupling having an internal thread in a cavity of the female coupling, said female coupling adapted for mounting into overflow and waste water plumbing for a bathtub the female coupling mountable so as to be adjacent the bathtub,
• a stop including an annular rigid sealing flange, said flange having a second diameter greater than said first diameter, an externally threaded cylindrical plug mounted to, so as to extend substantially orthogonally from, said sealing flange, said plug sized to snugly mate into said female coupling in threaded engagement therein, said threaded engagement drawing said sealing flange forwards said female coupling,
• at least one seal mountable between said flange and said female coupling to engage a rim of the bathtub formed around the aperture in the bathtub,
• a torque tool receiver mounted to said flange so as to be oppositely disposed to said plug, the torque tool receiver mating with a torque tool to rotate said plug in relation to said female coupling and into said threaded engagement,
• wherein said stop is rigid and not frangible so that to decouple from said female receptacle said plug must be unthreaded and completely removed from said cavity.
