Older installations, known as "high suite combinations", used a high-level cistern (tank), fitted above head height, activated by a pull chain connected to a flush lever on the cistern. When more modern close-coupled cistern and bowl combinations were first introduced, these were first referred to as "low suite combinations".
Often old toilets still have high-level cisterns in the service ducts. On the outside, the toilet is flushed by a handle (just like an ordinary low-level cistern toilet) although behind the wall this handle activates a chain. Sometimes a long flushing trough is used to allow closets to be flushed repeatedly without waiting for the cistern to ...
The modern toilet utilises a cistern to reserve and hold the correct amount of water required to flush the toilet 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 ...
It is designed to allow a shorter interval between flushes than individual cisterns.

A low-flush toilet (or low-flow toilet or high-efficiency toilet) is a flush toilet that uses significantly less water than traditional high-flow toilets. Before the early 1990s in the United States, standard flush toilets typically required at least 3.5 gallons (13.2 litres) per flush and they used float valves that often leaked, increasing their total water use.
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.
The cistern was partially underground, with the back curved wall and the two side walls partially covered and buttressed by the embankment, while the impressive straight front wall with alternating rectangular and semicircular niches was visible. Large openings in the niches of the upper level provided ventilation.
Urinals in an office restroom. A urinal (US: / ˈ j ʊər ə n əl /, UK: / j ʊəˈr aɪ n əl /) [1] is a sanitary plumbing fixture similar to a toilet, but for urination only. Urinals are often provided in men's public restrooms in Western countries (less so in Muslim countries).
