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 installed in a seat extending radially into the sidewall of a pipe or other fluid transfer line to isolate an installed portion of the fluid line for testing. The test baffle comprises a pair of gaskets to improve the effectiveness of the baffle in sealing or isolating the line and a domed central web to facilitate testing at increased pressures. The test baffle optionally further includes a lightweight, low cost ribbed construction and a means for removing the baffle from either the convex or concave side of the dome without leaving behind any portion of the baffle to impair fluid flow within the line. On removal, the baffle is flexed into a saddle shape and removed from the line without need for dismantlement of the line.
