Best Dual Flush Toilets Reviews 2022 [Flushing Option 2]

Best Dual Flush Toilets

Dual flush toilets are becoming popular every day. This is because they use little water to eliminate waste (both liquid and solid waste). For this reason, they are a rare type of toilet to have in your bathroom if you want to conserve water and save the environment. Apart from this, they lower your water bill as the right amount of water is used for different types of waste. But the question is, which are the best dual flush toilets in the market?

With so many dual flush toilets on the market, choosing the best of the best can be a daunting task. That’s why we conducted thorough research on your behalf to bring you the best dual flush toilets. There are several things that we took into consideration when selecting the toilets, such as the efficiency of the flush, gallons used per flush, comfort, the height of the rim, durability, and ease of installation.

What is a dual flush system?

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 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.

Dual flush vs. traditional toilets: Water consumption

Most 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 gallons per flush. This means that conventional toilets use more than double the amount of water utilized by dual-flush toilets.
