Method and apparatus for dislodging a test baffle in a fluid conduit following pressure testing without permitting fluid to escape. The invention provides a device for dislodging or unseating a test baffle, for releasing a pressure within the conduit contained by the baffle, and for removing the baffle without leakage or other fluid escape. A preferred apparatus according to the invention comprises a rigid plug adapted for sealing engagement of an end of a fluid conduit such as a pipe, and a removal device adapted to pass through an aperture in said plug and to engage and dislodge a test baffle disposed within an interior of the conduit. Preferred removal devices comprises flexible lines attached to the test baffle and tools adapted to pass through the aperture and engage the test baffle. A method aspect of the invention comprises the steps of substantially blocking or sealing an end of a fluid conduit with a plug, passing a removal device through an aperture in the plug, and using the removal device to unseat or dislodge a test baffle in the interior of the conduit.
