The main purpose in producing this innovative farming machinery is to reduce water, labor, and equipment costs associated with tradition siphon irrigation. Siphon pipes are commonly used in the agricultural industry for row crop irrigation. Traditional harvests involving this irrigation method include corn, beans, tomatoes, and alfalfa, among others. The irrigation method is commonly used throughout the United States, India, and Australia.

A device for controlling the filling of a cistern in a main reservoir of a toilet flushing system includes a water inlet controlled by a valve. The closing of the valve is controlled by a float that is movable from a high position to a low position. The float is contained in a float housing in the high position. The float housing connects to the main reservoir by at least one siphon having two tubes: a suction tube linked to the float housing; and a discharge tube being linked to the main reservoir and opening into an auxiliary reservoir. There is a control mechanism provided with a mechanism for priming the siphon, wherein shifts between an initial position and an actuated position of the control mechanism result in overpressure or underpressure at the siphon so as to control draining of the float housing.
