Dual Flush Toilet Buying Guide and Tips
What is the Minimum and Maximum Flush Rating?
Dual flush models use one setting to flush smaller chunks of waste and for liquids and a second for solid forms of waste. You should check the minimum and maximum settings to ensure the product has enough power to keep up with those living in your home.
A minimum setting is usually around 0.9 to one gallon of water. When looking at the maximum rating, you might see a figure of around 1.28 to 1.6 gallons. A larger setting will offer more flushing power, especially when paired with siphon technology or a canister bowl that moves the water faster.
You may want to look at those with a gravity design too that combines the flapper with the trapway. When the flapper lifts, gravity forces water straight down from the tank and into the bowl. A smaller water setting may not remove all the visible waste in the bowl.
Where is the Flushing Mechanism?
The flushing mechanism found on these products is different from a flushing handle or lever. It typically looks like a large button with two buttons built inside. Some place this button on the top of the tank, but others place it closer to the base.
Having a button on the top is more convenient for those who cannot or do not want to bend down and lets you flush from a standing position. Some prefer leaning down slightly and pressing the button right before standing up. Manufacturers sometimes make one of the two buttons slightly larger to let you easily see which one produces a larger flow of water.
Does it Use One or Two Pieces?
Some models use just one piece and have a molded design that incorporates the bowl with the tank, but others come with two pieces that separate those parts. A molded design is a good choice for those who want a cleaner look because these models lack any seams that can collect and attract dirt. Those that use two pieces let plumbers take away and repair or replace one piece and let you more easily carry the parts into your home via the shipping boxes.
