When more modern close-coupled cistern and bowl combinations were first introduced, these were first referred to as "low suite combinations". Modern versions have a neater-looking low-level cistern with a lever that the user can reach directly, or a close-coupled cistern that is even lower down and fixed directly to the bowl.
In earlier toilets, the cistern was located high above the toilet bowl and connected to it by a long pipe. It was necessary to pull a hanging chain connected to a release valve located inside the cistern in order to flush the toilet. Modern toilets may be close coupled, with the cistern mounted directly on the toilet bowl and no intermediate ...

A dual flush toilet; note the two buttons at the top of the cistern. A dual flush toilet is a variation of the flush toilet that uses two buttons or a handle mechanism to flush different amounts of water. The purpose of this mechanism is to reduce the volume of water used to flush different types of waste.
Note: These diagrams represent a configuration typical in the USA, mechanisms may vary in other countries [citation needed]. The toilet ballcock, long made of brass and later made of plastic, was superseded by the float cup, pioneered in 1957 by the Fluidmaster founder Adolf Schoepe , which is integrated with the tank’s fill valve and so ...
In the U.S., every plumbing fixture must also be coupled to the system's vent piping. [1] Without a vent, negative pressure from water leaving the system can slow flow (resulting in clogs) or cause a siphon to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.
Additional water pressurizing components such as pumping stations may need to be situated at the outlet of underground or aboveground reservoirs or cisterns (if gravity flow is impractical). A pipe network for distribution of water to consumers (which may be private houses or industrial, commercial, or institution establishments) and other ...
The cisterna magna (posterior cerebellomedullary cistern, [1] or cerebellomedullary cistern [2] [3]) is the largest of the subarachnoid cisterns.It occupies the space created by the angle between the caudal/inferior surface of the cerebellum, and the dorsal/posterior surface of the medulla oblongata (it is created by the arachnoidea that bridges this angle [3]).
