Thomas Crapper designed the flush toilet with the float valve and cistern sitting above the toilet, allowing water to remain in the bowl. For this invention we thank Mr. Crapper. Unfortunately leakage from the flapper valve in his design is the biggest source of water waste in homes and constitutes as much as 11% of municipal water waste. Surprised? So am I.
Niagara Flapperless Inc., co-founded by inventor of the first flapperless toilet Phil Hennessy could be the next generation of toilets. The design won the United Nation’s technology award in 2005. It is the first flapperless toilet that prevents water from seeping out.
The Financial Post reports more about having a Hennessy toilet replacement here.
