A dual-flush toilet is a variation of the flush toilet that uses two buttons or handles to flush different levels of water. It was proposed by American industrial designer Victor Papanek in his 1976 book Design for the real world, but the first practical implementation was designed by Australian inventor Bruce Thompson in 1980, while working for Caroma. Although the first generation dual-flush toilet caught on, a redesign in 1993 cut water usage in half when used properly. The dual-flush toilet has since become almost universally adopted in Australia, New Zealand, Singapore, and Israel, with its use in new buildings often mandated by legislation in those countries. However, due to the more complex mechanism, it is more expensive than many other types of low-flush toilets.
Mechanism
The traditional Australian flush toilet, the dual-flush toilet differs from siphon-flush toilets in that it relies on gravity to remove waste from the toilet. In addition to its dual flush feature, the lack of siphoning also results in it requiring less water to operate. The lack of siphoning also means that it is similar to an aeroplane toilet; the water line is considerably lower than that of siphon-flush toilets. The main feature of the toilet is that it has two buttons for releasing water. It outputs water in both 0.8 US gallon (3 litre) and 1.6 US gallon (6 litre) capacities. The smaller level is designed for liquid waste, and the larger is designed for solid waste. It also uses a larger 4-inch (10cm) trapway in the bowl, allowing for water to come out faster and clear the bowl efficiently.
A flush toilet is a toilet that disposes of human liquid and solid waste, by using water to flush it through a drainpipe to another location for disposal, thus maintaining a separation between humans and their excreta. Flush toilets can be designed for sitting (in which case they are also called "Western" toilets) or for squatting, in the case of squat toilets. The opposite of a flush toilet is a dry toilet which uses no water for flushing.
Flush toilets usually incorporate an "S", "U", "J", or "P" shaped bend that causes the water in the toilet bowl to collect and act as a seal against sewer gases. Since flush toilets are typically not designed to handle waste on site, their drain pipes must be connected to waste conveyance and waste treatment systems. When a toilet is flushed, the wastewater flows into a septic tank or sewage system and from there to a sewage treatment plant.
A flush toilet may be colloquially called a lavatory, a water closet (abbreviated W.C.), a loo, a comfort room (abbreviated "C.R.") and many other names.
