Abstract
A device to clear a blockage from a drain line draining condensation from an air handler in an air conditioner or heat pump. A pump with check valves attaches to one end of a drain line which drains condensation from an air handler for an air conditioner or heat pump. A handle on the pump is used to create respectively a vacuum or pressure within the pump which is communicated to the drain line. When sufficient vacuum or pressure is created, it will dislodge a blockage in the drain line allowing the drain line to naturally drain. A valve is placed at one end of the pump which allows accumulated liquid in a collection pan to be pumped from the collection pan in the process of clearing condensation from the air handler.
Claims9
A device to clear a blockage from a drain line draining condensation from an air handler in an air conditioner or a heat pump comprising:
- (a) a pump for fluid or gas with a cylinder, a piston disposed within said cylinder, a rod extending from said piston toward a first end of said cylinder and terminating in a handle outside of said cylinder;
- (b) at a second end of said cylinder, an outlet disposed for a gas or fluid tight fitting to a terminal end of a drain line;
- (c) at said first end of said cylinder, a valve, whereby said valve may be opened to allow fluid or air flow from said cylinder to an area outside of said cylinder.
A method to clear a blockage from a drain line draining condensation from an air handler in an air conditioner or a heat pump comprising:
- (a) attaching a pump, using a connection designed for connecting to a terminal end of a drain line at an outlet on said pump, to a terminal end of a drain line for draining condensation from an air handler in an air conditioner or heat pump;
- (b) withdrawing a handle from said pump creating a vacuum in said pump fluidly communicated to said drain line;
- (c) repeatedly withdrawing said handle to create a sufficient vacuum in said drain line to dislodge a blockage in said drain line allowing accumulated condensation in said air handler to drain from said drain line.
