Abstract
A fill spout for a drainage device is disclosed which permits the user to supply water directly to a water seal chamber of the drainage device for establishing a water seal therein. The fill spout comprises a funnel having lateral sides for facilitating the entry of the water into the drainage device, a depending lip extending from the fill spout for preventing any run off or spillage, and a tab having an arcuate-shaped rest which permits the user to open and close the fill spout. In use, the user pulls the tab which opens the fill spout and places a water-filled bottle against the rest. The user then pours a predetermined amount of water through the funnel and directly into the water seal chamber.
