Abstract:
1. A fluid system comprising: a test plug adapted to be received at least partially within a fluid conduit having (i) a drain component with a blow out window and (ii) a fluid passageway therethrough that extends from a first end of the fluid conduit to a second end of the fluid conduit, the test plug being adapted to substantially isolate the drain component blow out window from a pressure within the fluid conduit when the test plug is received at least partially within the first end of the fluid conduit; and a disk that can be directly or indirectly secured at the first end of the fluid conduit, the disk being configured to selectively close off the fluid passageway and prevent the flow of fluid out of the first end of the fluid conduit when a pressure within the fluid conduit is below a predetermined level, wherein the disk comprises a sacrificial element that is adapted for preferential failure when the pressure within the fluid conduit exceeds the predetermined level.
