FILL SPOUT FOR A DRAINAGE DEVICE

摘要

A fill spout (22) for a drainage device (10) is disclosed that permits the user to supply water directly to a water seal chamber (16) of the drainage device (10) for establishing a water seal (80) therein. The fill spout (22) comprises a funnel (42) having lateral sides (44,46) for facilitating the entry of the water into the drainage device (10), a depending lip (60) extending from the fill spout (22) for preventing any run off or spillage, and a tab (56) having an arcuate-shaped rest (62) which permits the user to open and close the fill spout (22). In use, the user pulls the tab (56) which opens the fill spout (22) and places a water-filled container (82) against the rest (62). The user then pours a predetermined amount of water seal (80) through the funnel (42) and directly into the water seal chamber (16).
