Abstract
An improved flush system as described herein may comprise a reservoir with a drain opening for egress of liquids disposed in the reservoir into a surrounding toilet tank. A lock mechanism is slidably received by the reservoir so that the lock mechanism is translatable between one or more fixed positions on the reservoir. In turn, translating the lock mechanism into the reservoir at increasing depths causes a size of the drain opening to be reduced and therefore adjusted.
