The disc is coupled to and movable relative to the diffuser and has an upstream face and a downstream face. The compression spring biases the disc into a normally open position during forward flow. A check valve apparatus further comprises at least one test bore through the valve member in communication with the disc. A method for testing the operation of a passive check valve is also disclosed.
