Dual flush toilets include two different flushing mechanisms that handle liquid or solid waste differently, allowing for better water conservation in arid parts of the world, in the midsts of a draught, or simply on behalf of environmental consciousness.
Gravity toilets are a very common flush mechanism in which the downward rush of water flushes waste out of the bowl.
Siphon Jet toilets are the most popular style of toilets found in American bathrooms. These units use an "S" shaped water way. When the toilet is flushed the water ways fill up with water and create the siphon effect. The bowl is then rapidly emptied due to the siphon action and stops emptying once the water level in the bowl drops below the first bend in the "S".
Double cyclone flush systems use two opposed propelled rinse nozzles that sweep water around the bowl more efficiently and powerfully.
offer increased flow, drawing water into the bowl more quickly, and then propelling it away more forcefully.
