ABSTRACT:
A device for leak-testing a pipeline system, of the type having a test tee fitting in a standpipe, includes a generally circular base plate for engaging an opening of the test tee, a wrench collar for tightening the base plate in the test tee, and a threaded bushing for filling the standpipe with water. A fluid channel passes through the bushing, wrench collar, and base plate, and a one-way valve is disposed within the fluid channel. A water hose is coupled to the bushing for passing water through the one-way valve into the interconnected pipeline system. After leak testing is completed, a sealing cap is secured over the bushing, and the device is left permanently in place after the test is completed.
