摘要：
A water saving device for a toilet adapted for mounting on an overflow tube above a flapper valve. The device uses a mainframe connected to the overflow tube to position a highchair that is pivotally mounted to the mainframe. A water cup is mounted to the highchair for weight and a vertical cam descends from the highchair to contact and close the flapper valve.
