Patent ID: 7281411

Claim:
A method 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 method comprising the steps of: a) providing a generally circular base plate having a threaded outer periphery for mating with the internal threads of the third opening of the tee fitting, the generally circular base plate having a fluid passage extending centrally therethrough; b) providing a wrench collar on the generally circular base plate; c) disposing the generally circular base plate within the third opening of the tee fitting; d) engaging a wrench with the wrench collar for tightening the generally circular base plate within the third opening of the tee fitting; e) providing 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 the 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; f) forming a one-way valve within the 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; g) attaching the end of a water hose to the threaded bushing and substantially filling the pipeline system with water; h) checking the pipeline system for leaks; and i) permanently leaving the generally circular base plate, wrench collar, threaded bushing and one-way valve in place within the third opening of the tee fitting after leak testing is completed.
