Mechanical flush from a high pressure water supply A float usually commands the refilling device. The water may be discharged through a "toilet flapper valve" (not to be confused with a type of check valve), or through a siphon. The second device automatically allows water to enter the tank until the water level is appropriate for a flush. The first device allows part of the contents of the tank (usually in the 3–6 liters range) to be discharged rapidly into the toilet bowl, causing the contents of the bowl to be swept or sucked out of the toilet and into the drain, when the user operates the flush. The water is directed around the bowl by a molded flushing rim around the top of the bowl or by one or more jets, so that the entire internal surface of the bowl is rinsed with water.Ī typical toilet has a tank fixed above the bowl which contains a fixed volume of water, and two devices. Tanks and valves are normally operated by the user, by pressing a button, pushing down on a handle, pulling a lever or pulling a chain. ![]() This flush may flow from a dedicated tank (cistern), a high-pressure water pipe controlled by a flush valve, or by manually pouring water into the bowl. After use, the bowl is emptied and cleaned by the rapid flow of water into the bowl.
