ABSTRACT:
A test fitting for installation in a plumbing system comprises an annular sleeve having opposed first and second open ends and an inner surface that defines an open interior space and a hole. A cord has a first portion removably positioned in the sleeve's interior space and a second portion extending through the hole for removing the cord from the interior space through the hole. The first portion of the cord forms a watertight spiral disc that extends across the interior space to define a first area completely separated from a second area, and an outer edge of the spiral disc may be supported by a ledge extending from the inner surface into the interior space. Means are included for selectively sealing the hole after the cord is withdrawn through the hole, such as a plug complementary to the hole.
