A fluid routing system for use in a fluid line is set forth which includes a fluid routing mechanism having a housing and a block, and a removable treatment device. The housing has an internal chamber, an inlet port for attaching to one part of a fluid line, an outlet port for attaching to another part of the fluid line, an inlet channel connecting the inlet port to the internal chamber, and an outlet channel connecting the internal chamber to the outlet port. The block is capable of movement between a first and second position and is disposed within the internal chamber of the housing. The block has a first internal cavity, a second internal cavity, an exterior surface, an inlet passageway connecting the first internal cavity with the exterior surface, and an outlet passageway connecting the second internal cavity with the exterior surface. The inlet passageway and the outlet passageway are configured to retain fluid therein when the treatment device is removed. In the first position, the inlet passageway of the block is aligned with the inlet channel of the housing and the outlet passageway of the block is aligned with the outlet channel of the housing for permitting flow of the fluid into the treatment device. In the second position, the inlet passageway of the block is misaligned with the inlet channel of the housing and the outlet passageway of the block is misaligned with the outlet channel of the housing for prohibiting flow of the fluid into the block.
