As people become more conscious of the impact they can have on the environment, dual flush toilets are becoming more popular. In this article, we will show you everything you need to know about dual flush toilets, including reviews of six of the best models currently on the market.

What Are Dual Flush Toilets?

Dual flush toilets are a great way to save water when you flush your toilet which can have a huge positive impact on water conservation over time, and can also save you a lot of money.

They have two flushing buttons. A level one flush for liquid waste which usually uses around 0.8 gallons of water per flush and a level two flush for solid waste which usually uses around 1.6 gallons of water per flush. Even a level two flush can save water when compared to an older style toilet which can use up to five gallons of water every time you flush.
