The fluid management system includes an upstream drainage portion in fluid communication with the drain and a downstream drainage portion; a flushing assembly having an inlet and an outlet, wherein the flushing assembly is in fluid communication with the upstream drainage portion and the downstream drainage portion; a filter assembly disposed with the upstream drainage portion; and a logic panel configured to actuate the flushing assembly between a flushing mode and a standby mode. When the flushing assembly is actuated to the flushing mode, the flushing assembly is configured to exert a negative pressure at the inlet and a positive pressure at the outlet. ## Claims ### Claim 1 A fluid management system for a drain, the fluid management system comprising: an upstream drainage portion in fluid communication with the drain and a downstream drainage portion; a flushing assembly having an inlet and an outlet, wherein the flushing assembly is in fluid communication with the upstream drainage portion and the downstream drainage portion; a filter assembly disposed with the upstream drainage portion; and a logic panel configured to actuate the flushing assembly between a flushing mode and a standby mode; wherein when the flushing assembly is actuated to the flushing mode, the flushing assembly is configured to exert a negative pressure at the inlet and a positive pressure at the outlet. ### Claim 2 (depends on 1) The fluid management system of claim 1, wherein the filter assembly comprises: a tee portion having a removable plug; and a conical filter at least partially disposed in the tee portion. ### Claim 3 (depends on 2) The fluid management system of claim 2, wherein the tee portion is transparent. ### Claim 4 (depends on 2) The fluid management system of claim 2, wherein when the flushing assembly is actuated to the flushing mode, the flushing assembly is configured to suction fluids through the conical filter. ### Claim 5 (depends on 4) The fluid management system of claim 4, the conical filter having an 6-10 mesh size. ### Claim 6 (depends on 1) The fluid management system of claim 1, wherein the filter assembly is located proximate the drain. ### Claim 7 (depends on 6) The fluid management system of claim 6, wherein the filter assembly comprises: a tee portion having a removable plug; a conical filter; and a biocide disposed with the filter assembly. ### Claim 8 (depends on 7) The fluid management system of claim 7, wherein the conical filter is coated with the biocide. ### Claim 9 (depends on 7) The fluid management system of claim 7, wherein the conical filter is formed of the biocide. ### Claim 10 (depends on 7) The fluid management system of claim 7, wherein at least one of the tee portion, removable plug, and conical filter further comprise a slot, and wherein the biocide is a tablet adapted to be inserted into the slot. ### Claim 11 (depends on 7) The fluid management system of claim 7, wherein when the flushing assembly is actuated to the flushing mode, the flushing assembly is configured to suction biocide from the flushing assembly. ### Claim 12 (depends on 1) The fluid management system of claim 1, wherein the drain is a drain of an air handler. ### Claim 13 (depends on 12) The fluid management system of claim 12, wherein the fluid is a condensate from the air handler. ### Claim 14 (depends on 1) The fluid management system of claim 1, wherein the drain is a drain of pan.
