Systems and methods for flushing shunt systems are disclosed herein. In some embodiments, a flusher includes a pinch tube that extends over a flush dome such that a user can simultaneously close the pinch tube and actuate the flush dome with a single motion. Flushing and refill valves of the system can be disposed in a cartridge that is laterally-offset from the flush dome, advantageously reducing the height profile of the flusher. Flushers with integrated shunt valves are also disclosed, as are shunt systems with restricted and unrestricted modes for selectively limiting the instances in which a user can open an auxiliary flow path through the system.
