Niagara Flapperless Beats the Crap Out of Normal Toilets

Migrated Image

Thomas Crapper didn't invent the eponymous bathroom device, he improved it and popularized it. The key invention of the siphonic action, where there is a complete water seal to stop smells and no valve on the outlet to fail (gaskets were leather 200 years ago and nobody wanted to fix them at the bottom of a toilet) came earlier. Crapper came up with the big float valve and cistern that sat above the toilet and metered out the water.

People didn't mind when that flapper valve leaked, because water still stayed in the bowl. Unfortunately they still leak, and flapper leakage is the single biggest source of water waste in a home- a small, invisible leak can waste 100,000 litres per year. The Niagara Flapperless gets rid of the flapper altogether; it holds the water in a hinged trough that tilts over and dumps the water all at once into the tank, with no resistance from the flapper mechanism to slow it down. Result: in the miso poop performance test, it passed 750 grams, almost a pound and a half. It will never wear out and leak because there is no rubber seal to deteriorate, which as we know from Richard Feynman, eventually they all do. ::Niagara Flapperless
