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.

[ I claim:] [1.] A test system for non-destructive testing of the fluid-tight integrity of an installed fluid transfer line, the system comprising:a baffle carriage adapted for disposition between ends of adjacent sections of a fluid transfer line and for releasably retaining a test baffle within an interior surface of the baffle carriage, said interior surface comprising a circumferentially disposed recessed seat and a recessed sidewall proximate said seat;a removable test baffle having a diameter larger than an inner diameter of said ends of said fluid transfer lines, the test baffle comprising a first gasket, a perimeter, and a central web, the first gasket adapted to engage said seat, the perimeter comprising a second gasket adapted to sealingly engage said sidewall, and the central web attached to said gaskets in a fluid tight engagement; anda sleeve having an inner surface adapted to accept within an interior of said sleeve said baffle carriage and to sealingly engage outer surfaces of said sections of fluid transfer line, and thereby to hold said carriage in a substantially coaxial relation to said sections, said sleeve further comprising at its inner surface at least one integral gasket adapted for disposition between one of said ends of said sections and said baffle carriage, and to act as a gasket therebetween.
