Passive ‘vacuum-assist’ technology that delivers a less noisy flush at just 0.8 gallons has been utilised by Niagara Conservation of the US in its latest toilet design and dubbed Stealth as a result.
Unlike ‘pressure-assist’ toilets that use compressed air at the top of a sealed tank to push water through the flush valve at a high velocity, the ‘vacuum-assist’ Stealth toilet pulls the contents of the toilet bowl down the trapway from below.
The Stealth toilet’s innovative features have helped it earn the EPA WaterSense label for ultra high-efficiency toilets (UHETs). Successfully passing all IAPMO requirements, this new design pushes waste 40 feet along the drainline upon being flushed.

Niagara Conservation claims that the system is not affected by fluctuating water pressure levels, and contains fewer parts than a conventional toilet. According to its calculations, it will reportedly save 37% more water than a standard high-efficiency toilet, which translates into as much as 20 000 gallons a year.
Despite the small amount of water it uses, the company claims that the powerful vacuum action will always clear the bowl in one flush. In addition, it is being billed as featuring ‘the quietest flush on the planet’.
Headquartered in Cedar Knolls in New Jersey in the US, with satellite offices around the world, Niagara Conservation manaufactures an extensive range of water-saving hardware.
