The Niagara 77001 WHCO1 Stealth 0.8 GPF Toilet with Elongated Bowl and Tank Combo, White is really the ultimate in a water conserving toilet. The Niagara 77001 WHCO1 Stealth uses just 0.8 gallons per full flush. Niagara claims that their very highly efficient flushing system thoroughly clears the bowl on the first flush every time, with no need to use a double flush. Although this is a very technologically advanced toilet in terms of water consumption, it looks very much like many other similar two piece toilets.
Design / Materials
The Niagara Stealth, manufactured from vitreous china, looks very much like a standard two-piece toilet with an elongated bowl. The clever bits of this toilet though are hidden from view. This is the most frugal and water efficient toilet thanks to the very well-engineered flushing system.
Not only does this toilet use just 0.8 gallons of water on a full flush it is also very quiet at the same time. A toilet that meets the Water Sense certification (1.28 GPF) are classed as HET (high-efficiency toilet). The stealth is the only toilet that is classed as U-HET (Ultra-high efficiency toilet). The efficiency of the flush is increased by the addition of an air channel between the waste pipe and the cistern. When the toilet is flushed the air pressure differential causes the waste pipe to act as a siphon to help draw the waste down the pipe with a greater force. This video from Niagara shows the flushing action in greater detail.
The Niagara Stealth claims that even with its incredibly low water usage it will clean the bowl first flush every time without the need for a second flush. To qualify for the Water Sense certification as an HET, the toilet must be capable of flushing 350g of miso paste per 1.28-gallon flush. The Stealth is capable of flushing 600g of miso paste with only 0.8 gallons of water.
The Niagara 77001 WHCO1 Stealth has the lowest consumption of any toilet currently on the market – it is the only U-HET toilet available. The Stealth is Water Sense certified, this means that in many areas rebates are given for buying this toilet, check here for eligibility.
Ease of InstallationThe toilet uses a standard 12” rough into the waste pipe. The installation is similar to other standard toilets. Although most toilets do not come with the waste seal (wax or wax-free) the Niagara Stealth does not come with the bolts to fix the toilet to the floor.
