Abstract:
1. A condensate drain line purge device comprising: a housing having a condensate inlet fluidly coupled to an outlet forming a chamber therebetween, said housing securable in an air conditioning condensate drain line; a plug positioned within said chamber, said plug movable to an upper seat when condensate floods said chamber to seal said inlet and prevent condensate from flowing back through said inlet; a solenoid valve having a gas inlet coupled to a disposable pressurized gas canister having a gas outlet fluidly coupled to said solenoid and said solenoid having an valve fluidly coupled to said housing chamber, said solenoid valve electrically coupled to a condensate holding pan float switch; wherein condensate flows through said housing until a drain line clog occurs causing condensate to back up wherein the floating plug seals said condensate inlet and said solenoid valve is actuated by the float switch allowing pressurized gas into said chamber to purge the drain line of the clog.
