Product Overview

.

Innovative and stylish, Niagara’s 0.8 gallon per flush (GPF) ultra high-efficiency toilet (UHET), goes a step beyond the standard water-saving toilets on the market. With its quiet flush, low-profile body and breakthrough patented hydraulic technology, the Stealth has revolutionized the toilet market. It is offered in both round and elongated models and adaptable to fit a standard 12” roughing installation. The Stealth easily replaces your existing toilet, offering superior performance and lowering water usage and utility bills like no other toilet can.


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.

AIR TRANSFER TUBE - 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.

SEAL - No Flapper. No Leaks. Less Water Wasted. 

he 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 vacuum-assisteding in refilling the toilet.

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.

A 2” Fully Glazed Trapway 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.
