ABSTRACT:
The present invention relates to an adjustable valve for a toilet in which the valve remains in a lower setting unless it is activated by the user to a higher setting and automatically returns to the lower setting after flushing the toilet. The amount of water used for each flush is dependent on the water level in the toilet tank. The water level in the tank is set by adjusting the height of the valve assembly. The valve assembly can be activated by the user to raise the height of the valve assembly and maintain the height using a release clip, thereby increasing the amount of water in the tank. When the handle is pressed to flush the toilet, the release clip is pulled back by a chain extending from the handle and the adjustable valve springs back to the lower setting.
