Abstract

The invention relates to a cistern, in particular an in-wall cistern, for a toilet or urinal, with a drain valve which has a closure body which can be lifted from a closed position into a flushing position. The closure body is designed as an overflow pipe and has a seal which rests tightly on a valve seat in the closed position, with at least one water intake line, with a valve assembly for letting in drinking water present in the water intake line, with a water discharge line for discharging the drinking water let in by the valve assembly, and with a controller which generates a control signal for actuating the valve assembly as a function of a sensor signal and/or when a predefined time interval has been exceeded.
