TOTO 1G Toilets - Are They Effective?

TOTO 1G toilets are high-efficiency toilets designed to reduce water usage without compromising performance. They are known for their innovative design and water-saving features, but should you elect for one over a standard flush volume?

TOTO 1G toilets are a series of high-efficiency toilets that are designed to use one gallon per flush (gpf) or less, making them significantly more water-efficient than traditional toilets.

TOTO 1G toilets offer several benefits, including:

  • Water Savings: They can save up to 35% more water than standard 1.6 gpf toilets, resulting in significant water savings over time.
  • Performance: Despite using less water, 1G toilets are known for their powerful flush and effective waste removal.
  • Environmentally Friendly: By using less water, 1G toilets help conserve water resources and reduce the strain on water treatment facilities.

If you have ever flushed a Toto toilet, you may have noticed how strong the flush is. This is due to their signature Tornado Flush system that is utilized in all their toilets. The system features two powerful nozzles that create a centrifugal, cyclonic rinsing action which reduces waste buildup and keeps the bowl cleaner. This high-efficiency system is more effective in one flush than most toilets are with multiple flushes. The modern hole-free rim design means that it performs more consistently and is easy to clean.


How the Tornado Flush system works

In addition to the Tornado Flush system, most TOTO toilets use a patented glaze over the ceramic structure that is extremely smooth and prevents particulates in the bowl from sticking to the surface. The glaze is called CEFIONTECT, and we have an upcoming blog post devoted to it. When combined with Tornado Flush, this glaze allows for a clean flush with nothing left behind. 

Starting in 1994, all consumer toilets produced in America were mandated to use 1.6 gallons per flush or less. Most of TOTO's catalogue are 1.28 GpF models, which does not sound like much more than 1 gallon, however the more than 20% water savings can add up over time. This is especially true in larger households. 

TOTO 1G toilets are highly effective in saving water and reducing water bills. Their innovative design and advanced flushing mechanisms make them a practical and environmentally friendly choice for modern households.
