Dual flush toilets are interactive toilets that handle solid and liquid waste differently by presenting the user with a choice of flushes. Initially promoted in areas where water was and continues to be in short supply, such as Australia, the dual flush toilets are becoming increasingly popular for many North Americans as well. Rising water costs and increased environmental awareness have led many consumers to perceive the dual flash technology as an attractive alternative to conventional toilets.
However, many homeowners who are still reluctant to this changeover keep wondering if dual flush toilets really save water. The fact is that the dual flush toilet technology can save up to 70% more water than a traditional low-flow toilet and that is all due to the way dual flush toilets work. In order to understand the water efficiency of a dual flush toilet, you need to understand that the way water is used to remove waste from the bowl has a significant influence on how much water is needed to get the job done.
Dual flush toilets have two distinctive features that make them more efficient as far as water consumption is concerned: a large trapway and a wash-down flushing design. The role of the wash down flushing design is to push the waste down the drain and the role of the large trapway is to make it easy for waste to exit the bowl using less water. That is essentially what allows the dual flush toilets to use less water for the same results. In addition, you have the option of a half-flush or a full-flush with the push of a button, which again adds up and makes the dual flush toilets more water efficient and environmentally friendly.
