You’ve probably seen them in a public restroom or at a friend’s house. What do you know about dual-flush toilets? Below, we’re answering the most frequently asked questions about latest type of toilet to invade American homes.
A dual-flush toilet is a toilet that allows the user to choose how powerful the flush is. Most dual-flush toilets have two options (hence the name), a smaller flush and a larger flush.
2. What are the different flushing options on a dual-flush toilet and what are they used for?
As mentioned previously, dual-flush toilet have two options. The first is a lighter flush meant for smaller jobs (liquid waste) that typically uses 0.9 or 1.0 gallon of water per flush. The other flush is heavier and meant for larger jobs (solid waste) and uses 1.28 or 1.6 gallons per flush.
3. How are dual-flush toilets flushed?
There are a few different dual-flush lever options on the market today. Some toilets have what appears to be an average lever. The lever is raised for one flushing option and lower for the other. More commonly, a button at the top of the toilet controls the flush. The button will be divided into two sections, usually labeled 1 and 2. Press 1 for liquid waste and 2 for solid waste. These buttons are more often than not at the top of the toilet, but can also be found on the right or left side as well.
4. Should I choose a toilet that uses a maximum of 1.6 gallons per flush or 1.28 gallons per flush?
More is always better, right? Not in this case. Nationwide, the most a new toilet is allowed to flush is 1.6 gallons per flush, however many states have even stricter regulations. California, Georgia, and more limit water usage to 1.28 gallons per flush with many more states set to follow. With toilet technology improving every day, today’s 1.28 gpf toilets can clear what a 1.6 gpf toilet could clear two years ago.
A dual-flush toilet that uses a maximum of 1.28gpf is a smart choice that will last for years.
5. Can 0.9 gallon of water really flush the toilet?
Yes! In fact, TOTO makes a toilet that only uses 1 gallon per flush with no option to use more water. Toilet technology has improved and evolved so rapidly in the past five years that 0.9 gallon per flush can get most jobs done. Dual-flush toilets always have the second, more powerful flushing option if the need arises.
6. What are the benefits of a dual-flush toilet?
