A valve assembly which is placed in an air conditioner drain line for cleaning and maintenance of the drain line. The valve may be positioned to permit water or condensate to run through the drain line to a sewage drain. When the line needs to be serviced, usually due to clogging, the valve plug can be rotated to seal off the drain line upstream or downstream of the valve assembly. A slight pressure or vacuum may then be introduced at the top of the valve to force clogs loose. The valve also has a receptacle at the bottom so that an anti-fungus pellet may be dropped in which inhibits the fungus growth.
