How Does a Dual Flushing Toilet Function?
The dual flushing toilet functions on the premises of two types of flushing abilities - a short flush and a long flush.
Short flushing or a half flush is used when removing liquid. The dual flush model uses less than a gallon of water to remove the liquid. The water removed is mainly the water that is already in the bowl.
A long flush is used to remove solid excrement. The dual flushing toilet uses about 1.5 gallons of water to remove the waste. The 1.5 gallons includes the amount of water that is already in the bowl, as well as some of the water released from the bank. The water to remove solids is approximately one to two gallons of water for every flush. At one to two gallons of water usage, this is still less than water than standard, older toilets.
Water and Waste Elimination
The dual flushing toilet uses the power of water for flushing, resulting in less water usage. Older toilets use a combination of the power of the water and air to remove waste. In the dual flush models, the hole at the bottom of the bowl, called a trapway, is larger than those found in standard toilets, allowing the water to move fast and remove the waste.
