A typical flush toilet is a fixed, vitreous ceramic bowl (also known as a pan) which is connected to a drain. After use, the bowl is emptied and cleaned by the rapid flow of water into the bowl. 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.
Some modern toilets pressurize the water in the tank, which initiates flushing action with less water usage. Another variant is the pour-flush toilet. [3] This type of flush toilet has no cistern but is flushed manually with a few liters of a small bucket. The flushing can use as little as 2–3 litres (0.44–0.66 imp gal; 0.53–0.79 US gal). [3]
When the handle of a flush toilet with a tank (British, cistern) is turned, a discharge mechanism is activated by means of a rod or chain. The mechanism may be a flapper valve, which is designed to sink more slowly than the water - allowing the water to exit to the toilet bowl below, so that the tank may empty.
A flushing trough is a type of cistern used to serve more than one WC pan at one time. These cisterns are becoming less common, however. The cistern was the genesis of the modern bidet. [citation needed] At the beginning of the flush cycle, as the water level in the toilet cistern tank drops, the flush valve flapper falls back to the bottom ...
The lever arm connecting the siphon plate to the flush chain was often fixed directly to a pivot on the siphon rather than the cistern, so the arrangement of the siphons was highly flexible: flush pipes could be fitted in the middle or side of the cubicles; flush chains could be arranged at the back or front of the trough, or through the bottom ...
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.
Ben Roche, director of wastewater at Yorkshire Water, said: “Consumers are currently faced with an array of different logos and claims on packets of wet wipes, including ‘fine to flush ...
This may be the flushing sort, which is plumbed into a cistern (tank) operated by a ballcock (float valve). Or it may be a dry model, which does not need water. The toilet room may also include a plunger, a rubber or plastic tool mounted on a handle, which is used to remove blockages from the toilet drain. Toilets often have a wall mirror above ...
