Vacuum assisted flush technology could save homeowners thousands of gallons
One of the most water efficient toilets on the market does it with help from air pressure.
Niagara Conservation introducted the Stealth UHET Dual Flush. Equipped with two flush options—0.5 gallons per flush (GPF) half and 0.95 GPF full — this ultra-high-efficiency toilet (UHET) meets EPA WaterSense criteria and uses an average of 0.65 GPF. This makes it possible to save more than 15,600 gallons of water annually compared to the older 3.5 GPF toilets. Engineered with patented Stealth water-saving technology, the Stealth UHET Dual Flush is an easy, effective way to reduce water usage and utility costs.
At the Greenbuild Expo, Matt Voorhees, national accounts manager, reviewed the operation of the Stealth Dual Flush toilet.
According to Vorhees, the Stealth UHET Dual Flush offers users the option of a flush utilizing half the normal amount of water, or a full flush when needed. It includes a low-friction ceramic surface and fully glazed two-inch trapway, providing superior performance and eliminating the need for double flushing. The large water surface in the Stealth UHET Dual Flush toilet helps ensure that the bowl’s surface stays clean. The product features a 10-year limited lifetime warranty and meets ADA height requirements. The Stealth technology involves a remarkable combination of air and water working in unison to ensure the bowl is completely cleared in one reliable, incredibly quiet flush.
How it Works
After flushing, water fills the tank and air is forced to the top of the chamber, through the transfer tube and into the trapway. As a result, the trapway is pressurized, creating larger water surface area in the bowl. When the half flush button is depressed, the Stealth Vacuum-Assist Power Chamber is sealed off to form a suction that prevents the water inside from being included in the flush. The suction force then pulls the wastewater into the trapway. As water empties from the tank, the trapway is filled completely, producing an ultra-high-efficient, quiet flush.
The Stealth UHET Dual Flush meets all standards set by the American Society of Mechanical Engineers (ASME). In addition, Dual Flush toilets are designed without flappers, reducing replacements costs and further saving the homeowner money.
