The 5 Best Dual Flush Toilet Reviews in 2020

Do you always have excessive monthly water bills that put quite a strain on your pocket? Maybe you have tried water-saving practices – you don’t let the water run when you’re brushing your teeth, or you make sure to use the dishwasher only when it is full – to no avail.

If despite all efforts, your water usage remains high, maybe you should consider another factor. Most people don’t think of it. Flushing the toilet is one major way of water being used in a household; it is also one of the most easily ignored. Most people don’t know that so many gallons of water are lost when you flush the toilet every time you use it, and you use it a lot every day, especially when there are kids in the home.

An article from the New York Times revealed that toilets manufactured in the 1980s use 3.5 gallons of water for every flush. So, put this into context, 5-gallon bottles are provided with water coolers. This means that you use up more than one of these bottles after just two flushes of your toilet. 

That is flushing a lot of water down the drain, and sometimes that much water is not even necessary when it’s a just liquid waste you’re flushing away.

A solution? Yes, Dual flush toilets.

Dual flush toilets are very effective ways of flushing your toilet and conserving water at the same time. They don’t need a lot of water so you can reduce your monthly water bill. These kinds of toilets have two buttons for partial flush (for liquid waste) and full flush (for solid waste) with the partial flush consuming less water than the full flush.

If you are thinking of getting a dual flush toilet mechanism at your home, we have put together a list of the best dual flush toilets in 2020. Please read our reviews and decide which one is best for you.

What is a Dual Flush Toilet?

Dual flush toilets are variations of the regular flush toilets. You can use either of two provided handles or buttons to flush your toilet after using it. The buttons or handles flush with different amounts of water.

Unlike the siphon-flush toilets, the toilets use gravity to aid the removal of waste. This is one of the major reasons why this toilet operates with less water than the siphon-flush toilets. These toilets are very effective in reducing your water usage and, consequently, your water bill.

Most toilets meet the ADA requirement of using not more than 1.6 gallons of water for every flush. According to the United States Environment Protection Agency (EPA), toilets are responsible for about 30 percent of a household’s water consumption. This emphasizes the advantage of using a dual flush toilet.

How Does a Dual Flush Toilet Work?

The idea behind a toilet is to have the option of choosing the amount of water you want to use for each flush. The partial flush removes fluids while the full flush is used for solid waste. These toilets usually have two buttons or levers that operate the partial or full flush systems. The difference in the way these toilets handle liquid and solid waste is a huge part of how it conserves water.

One of the reasons why toilets do not use much water for their operation is because they also rely on gravity for flushing. This reduces the chance of your toilet clogging, making its maintenance much easier.

The small volume of water these toilets use for operation, the dual flush option, and the gravity-assisted flush are the three things that separate the dual flush toilet from any other toilets in the market today.
