In 2009, Niagara Conservation put toilet technology on a higher plane. The idea was simple: create a flush that used the least amount of water while delivering a powerful and quiet performance. We have re-engineered the flush for a high-power, low-maintenance, no-waste toilet. The MOST EFFICIENT toilet on the planet. Our patented Stealth Technology® has a vacuum-assist pull so water doesn’t have to do all the dirty work and a noise-cancelling tank so your business is your business. Welcome to the water revolution!

One Flush or Two?

Our Patented Vacuum-Assist Technology That Delivers a Powerful Flush.

Before Flush: When water fills the tank/inner chamber, air is pushed back into the patented air transfer tube. This pressurizes the trapway priming the toilet for a powerful and quiet flush.

During Flush: When the flush button is pressed, water leaves the Stealth inner chamber and pulls air from the trapway up through the air transfer tube. This creates a vacuum-assisted pull that accelerates the force of the water and waste flowing through the trapway. Once the flush is complete, the system refills and is primed for the next flush.


The Stealth Dual Flush has primary and secondary chambers for either a full or half flush. When the “half” flush button is pressed, only the primary chamber is used, releasing 0.5 gallons of water to handle liquid waste. A “full” flush utilizes both chambers for additional power to accommodate solid waste. The secondary chamber is not used during half flush.

Noise Canceling Tank

Equipped with a Fluidmaster 400A Fill Valve...
That You Will Never Hear!

We have dramatically reduced the noise of the fill valve. Because such little water is used, the valve is never exposed.
It remains submerged, canceling out the noise produced.

No Flapper. No Leaks. Less Water Wasted.

The 360° water flow goes into the bowl faster and easier than a standard flapper as there is no blockage from objects. The Stealth seal is backed by a hard plastic plate that presses down and equally distributes pressure across the seal. This ensures that water does not leak while a standard flapper is prone to leak due to watering and lack of support.

Inside the Bowl

Specially Designed Rim Holes and Siphon Jet

When the flush button is pressed, water leaving the tank is forced through strategically placed holes around the rim to thoroughly rinse the surface. The larger front opening channels water directly down into the trapway while the smaller holes clean the remaining surfaces around the bowl.

The siphon jet hole is smaller than a typical toilet and is located in an area where it can quickly force water from the bowl into the trapway. The smaller size causes a more direct siphon action that quickly removes waste from the bottom of the bowl while assisting in refilling the toilet.

Large Water Surface

As the water begins to fill the inner chamber, air is pushed through the transfer tube. This air pressure exerted in the trapway forces water in the bowl to rise, creating a large water spot.

Inside the Bowl

Fully Glazed 2” Trapway

The 2” diameter is specially configured to be as streamlined as possible for the most efficient and powerful flush possible. No pitch points or drastic changes in direction. Fully glazed means reduced friction and zero absorption into ceramic material; which helps prevent clogging and increases the flushing performance.
