Condensate management system and methods

A method for purging a condensate drainage system for an air conditioning system, wherein the air conditioning system comprises a compressor and a drain pan, the method comprising:

• providing the condensate drainage system with a flush line having a pump fluidly connected to the condensate drainage system;
• providing a check valve with the primary condensate flow line, wherein an inlet of the flush line is fluidly connected to the primary condensate flow line upstream of the check valve, and an outlet of the flush line is fluidly connected to the primary condensate flow line downstream of the check valve;
• alerting a logic panel to a condition for flushing the condensate drainage system;
• in response to the alerting the logic panel the condition for flushing, energizing the pump to pull fluid from the inlet of the flush line and discharge fluid to the outlet of the flush line, wherein the pressure differential caused by the pump causes the check valve to close;
• de-energizing the pump;
• and
• determining whether the condition for flushing the condensate drainage system is resolved.
