Unlike the predominantly used water tanks with a bottom valve, the flushing process is initiated in water tanks of this type that a venting of the trapped in the first Heberrohrelement after filling the channel box air is enabled. Thereafter, to ensure complete emptying of the water box, the siphon action must be maintained during the rinse. For this purpose, the vent unit must be closed again in the manner of a check valve immediately after venting.
