FAQ

Question: What is a dual flush?
Answer: A dual flush toilet comes with two flushing options. The first option is a partial flush that clears liquid waste, while the second flush is a full flush that removes solids. Usually, the partial flush uses half or even less water than what a full flush uses. In the process, water is not wasted as the right amount of water is used for different wastes. The dual flush system is usually located on the top of the toilet tank. It comes in the form of two buttons.

Question: Do dual flush toilets use a lot of water than traditional toilets?
Answer: No. Most of the dual flush toilets use 1.28 GPF on average. Some units even use lesser water than that. But when it comes to traditional two-piece toilets, they use at least 3.5 GPF. This means that conventional toilets use more than double the amount of water utilized by dual flush toilets.
