It was necessary to pull a hanging chain connected to a release valve located inside the cistern in order to flush the ...

[7] It also uses a larger 10 cm trapway in the bowl, allowing for water to come out faster and clear the bowl efficiently.
It is designed to allow a shorter interval between flushes than individual cisterns. Flushing troughs were commonly used in places such as schools, colleges, public toilets, factories and public buildings where repeated use of the flushing cistern was required in a short period of time. Such troughs were used by local councils in the UK into ...
If the toilet is flushed from a tank, a large holding cistern is mounted above the toilet, containing approximately 4.5 to 6 L (1.2 to 1.6 US gallons) of water in modern designs.
