<p>A tube is disclosed for coupling to a spigot, including a first opening at a first end of the tube providing for fluid flow parallel to the tube axis, a second opening at the opposite tube end, and a third opening in the tube wall between the tube ends. A connecting means includes a washer so as to seal the tube to the spigot. The tube is rotatable between two configurations. In a first configuration water exits via the second opening while the third opening is directed upwardly. In the second configuration water exits the third opening which is directed downwardly after the tube has been rotated a half turn about the spigot.</p> |
