ABSTRACT:
An assembly mounts between the drain pan that collects condensate water from an air conditioner and the drain line. It includes a housing with a first end connected to the pan. A second end connects to the drain line. A shut off valve shuts off the passage to the pan while maintenance is performed. A connector is mounted on the housing between the valve and the second end. It is a female member of a quick-connect coupling. A male member of the coupling may be plugged in with a single motion to seal it in place. Male members have different terminations, including a barbed tube for resilient tubing, a compressed air tire valve for delivering gas, a female water hose coupling, a tapered funnel for the nozzle of vacuum/blower, and a water sensor.
