摘要：

A water change system includes an elongate tube and a spout configured to be coupled to the elongate tube. The spout includes a first opening and a second opening spaced from the first opening. The spout is rotatable between a first position to permit water to enter the second opening and pass out of the first opening, and a second position to inhibit water from entering the second opening.
