Abstract:
1. A leak-testing device for leak-testing a pipeline system, the pipeline system including a standpipe, the standpipe including a tee fitting, the tee fitting having a tubular section extending between first and second opposing openings axially aligned with each other, the tee fitting including a third opening communicating with the tubular section of the tee fitting and having internal threads, said leak-testing device comprising in combination: a) a generally circular base plate, said circular base plate having a threaded outer periphery for threadedly engaging the internal threads of the third opening of the tee fitting, said generally circular base plate having a fluid passage extending centrally therethrough; b) a wrench collar attached to said generally circular base plate and adapted to be engaged by a wrench for tightening said generally circular base plate within the third opening of the tee fitting; c) a threaded bushing having a fluid passage extending centrally therethrough, the fluid passage of said threaded bushing being axially aligned with, and in fluid communication with, the fluid passage of said generally circular base plate, the fluid passage of said threaded bushing and the fluid passage of said generally circular base plate collectively forming a fluid channel, said threaded bushing being adapted to engage an end of a water supply hose to fill the standpipe with water through said fluid channel; d) a one-way valve disposed within said fluid channel for admitting water through the fluid channel into the standpipe, while preventing water from escaping through the fluid channel out of the standpipe; and e) said leak-testing device being attachable to the third opening of the tee fitting of the standpipe without extending into, and without obstructing fluid flow within, the tubular section of the tee fitting.
