Abstract
The smaller volumes of water currently required to flush toilets and urinals may be insufficient to clear the fixtures and the drainage lines to which they are connected of waste and other undesirable materials, which can build up over a period of flushes or non-use. A flush valve control device programmed or otherwise configured to provide a selectable, periodic heavier flush volume of water after a predetermined number of low volume flushes and/or after a predetermined period of inactivity of the toilet or urinal can provide for sufficient drainage line carry-out of waste and prevent undesirable buildup of minerals, etc. on the inside surfaces of the fixtures and drainage pipes.
