ABSTRACT:
An improved system for the non-destructive testing of the fluid tight integrity of an installed fluid transfer line such as a drain pipe or vent and wastewater system of a building. A removable test baffle is held in place between ends of adjacent sections of an installed fluid transfer line to isolate a portion of the line for testing. The test system comprises a baffle carriage, a removable test baffle, and a sleeve adapted to engage the outer surfaces of the adjacent sections to seal the junction and the test installation from leaking and optionally to provide one or more gaskets between the section ends and the baffle carriage. In optional preferred embodiments of the test system the baffle carriage is an integral part of the sleeve. Preferred baffles for use with the invention are flexible, of larger diameter than the fluid line, and comprise dual-gasket sealing means and means for removal of the baffles from either side of the test seal. Baffles according to the invention may be completely removed from the fluid transfer line after testing, without risk of blocking or obstructing the fluid line.
