These timer controls are generally only recommended for washrooms that require flushing at regular intervals. For example, if the urinals are in heavy use 24 hours per day, then a simple control
(Gentworks Flush Timer) to limit flushing to, say, every 30 minutes is all that is required. Another application for a timer control
(Gentworks Low Flush) is for urinals converted to accept mushroom-like cartridges dispensing active ingredients to dramatically reduce the need for water. Such urinals typically require flushing every 4 to 12 hours. For more details on this method of urinal water saving, please
