Breakthrough Stealth Toilet Cuts Water Use Nearly in Half
Toilet technology is one of the most underappreciated yet important aspects of green building. Niagara Conservation‘s revolutionary Stealth Toilet features a vacuum assist that steeply reduces the water it takes to do your business – it uses only 0.8 gallons per flush compared to the EPA maximum of 1.6 gallons. There are many engineers who spend sleepless nights conjuring a better way to make a toilet flush, and in this case the design secret is an air bubble. Hit the jump to learn how it works and see the most realistic toilet test permissible for a G-rated audience.
After you flush the Stealth Toilet, a special tube transfers air to the trapway below the tank. That air bubble displaces the water in the trap, which then pushes the water up into the bowl. This results in a dramatic reduction in water, and as you flush the air creates a vacuum that effectively discharges the bowl. Compared to the pressure tank type that can make a racket when flushed, the Stealth Toilet is similar to a regular toilet in decibels. To see it in action, take a look at this rather evocative video. The toilet has performed admirably in the industry standard Maximum-Performance (MaP) testing procedure and is competitively priced with a suggested retail of $305 for the standard model.
