Abstract
A siphon for use with a flush type toilet having a tank with a drain hole at the bottom. The siphon comprises a vertical tubular discharge portion including a vertical tube which is secured within the drain hole in the bottom of the tank. The siphon also includes a bell shaped inlet portion including a connecting portion having a downwardly extending tubular portion for telescopic insertion into the vertical tube. A hole is defined in the bell shaped inlet portion and an elbow is secured within the hole and extends downwardly, terminating at a height selected to define the desired flush height of the toilet. The flush volume can be automatically set to either a normal or low volume flush with a control that includes a sensor that senses the presence of a user at the toilet.
