In the 1980s, the state of Massachusetts created regulations requiring all new toilets to use 1.6 gallons per flush (gpf) or less. This water-saving technique was soon adopted nationally by the US government, and since then, TOTO has created and stringently tested toilets to meet and exceed the requirement. The following TOTO flushing systems represent the company’s long history of abiding by federal guidelines while offering products that remain better than ever.
The most popular system used in TOTO toilets, toilets with G-Max are consistently recognized as the best flushing toilets on the market. G-Max toilets have a 3 inch flush valve and a fully glazed trap allowing waste to be easily disposed. A powerful siphon jet action also helps to clear the bowl quickly and consistently.
All toilets with G-Max use 1.6 gallons of water per flush. However, several states have new regulations that require all new toilets purchased must use 1.28 gpf or less. If you live in one of these states or want a more water-efficient toilet, try a toilet with the E-Max flushing system.
The eco-friendly version of G-Max, E-Max toilets have all of the power and capability of the G-Max system, but only use 1.28 gallons of water per flush.
The best compromise between saving water and getting the job done is a dual-flush toilet. Dual-Max is TOTO’s dual-flush system. Each toilet has the option of a 0.9 gallon flush or a 1.6 gallon flush depending on the button pressed, letting the homeowner choose the amount needed at their discretion.
The Double Cyclone flushing system uses the power of gravity combined with centrifugal force to environmentally and efficiently flush the toilet. Water drops from the toilet tank and is then pushed out of two nozzles that force water to circle the bowl, cleaning as it flushes. Double Cyclone toilets also use 1.28 gallons of water per flush, ensuring that they will be legally available in any state. Check out the following video for a demonstration of the Double Cyclone system:
Found in the luxury Neorest toilets, the Cyclone flushing system is just like the Double Cyclone system, only it uses one powerful nozzle of water instead of two due to the Neorest not having a tall tank. The Cyclone is a quiet both when flushing and when refilling afterwards, and the amount of water used per flush varies from 0.8 to 1.6 gallons.
The latest in TOTO’s long line of flushing systems, the Tornado system employs three separate water jets placed around the inside of the toilet bowl to wash away debris quietly and extremely efficiently. Furthermore, toilets that contain the Tornado flushing system also have no rim along their upper edge, thereby greatly limiting the amount of germs and other small materials that would otherwise gather in areas of the toilet hidden to the eye.
