ABSTRACT:
Provided is a hydraulic time release system for regulating the flow of liquid therethrough. The time release system comprises a timer body having a timer inlet for providing liquid at a timer inlet flow rate and a timer outlet for discharging liquid at a timer outlet flow rate. The timer body is divided into a first reservoir, a second reservoir, a third reservoir and a float reservoir. The first reservoir includes a catch pan mounted on an open drain tube that is positioned below the timer inlet. The first, second and third reservoirs are in at least partial fluid communication with the float reservoir. A timer float assembly is moveable between open and closed positions in response to variations in the float reservoir liquid level. The closed position is such that the flow of liquid into the drain tube is blocked causing the timer body to fill with liquid whereupon the timer outlet flow rate is substantially equivalent to the timer inlet flow rate.
