Dual flush toilet

Toilet dual-flush is a variation of flush toilets using two buttons or handles to water different amounts of water.

This system was proposed by American industrial designer Victor Papanek in his 1976 Design for the real world, but the first practical implementation was designed in 1980, by staff at the Australian sanitary-ware company, Caroma. Although the first-generation dual-flush toilets were caught, the redesign on the 1993 use of water cuts to half as compared to the traditional toilet, when used properly. The dual-flush toilets have since almost universally been adopted in Australia, New Zealand, Singapore, and Israel, with their use in new buildings often mandated by law in these countries. However, due to the more complex mechanism, it is more expensive than many other low-flush type restrooms.

Mekanisme

Since this is a traditional Australian flushing toilet development, the double sprinkler is different from a hot-watered toilet that relies on gravity to remove dirt from the toilet. In addition to the dual-flush feature, the lack of suction also means that the toilet requires less water to operate. The lack of suctioning means that the water line is much lower than in the filtered toilet. The main feature of the toilet is two buttons on the tank, which release different water volumes: one button produces 3 liters and 6 liters more. Less amounts are designed to flush liquid waste and larger ones are designed to flush solid waste. It also uses a 10 cm larger trap in the bowl, allowing water to come out faster and clean the bowl efficiently.

Benefits

The dual-flush toilets, due to their water-saving capabilities, have been promoted by the Australian Government under the "Target 155" campaign. The first dual-flush toilets have 4.5 liters (half) and 9 liters (full) flush, but innovations by Caroma lower them to 3 liters and 4.5 liters each, achieving WELS 4 and 5 star ratings in Australia.

The Australian Government has used a rebate to encourage the replacement of the toilet with one old flush with a more water-efficient. For dual-flush toilets, with a rating of 4 or more stars, the owner may be eligible to claim a rebate from the State Government in Victoria, New South Wales or South Australia. The Water Water rebate program ends on June 30, 2011.

Disadvantages

Like most design changes, an increase often involves trade-offs with other factors. In this case, although the toilet reaches its goal to conserve water, it may cost more than one flush toilet. If retrofitting in an existing toilet seat, there may be additional costs involving building modifications, but the retrofitting system has significantly lowered the price, at a cost of about US $ 30.

Lower water levels in double flush toilet bowls may be of little disadvantage to visitors to Australia from countries where toilets with full tanks and one lever/knob are the norm.
