Omnia GreenGain Toilet Goes Ultra Low-Flow

If you’re on the search for an ultra low-flow commode, consider the Omnia GreenGain from Villeroy and Boch. It knocks the standard 1.6 gallons per flush (GPF) of a low flush down to just .96 GPF, and offers an even lower option for, um, light loads.

How does it work? According to the company, it’s an innovative water distribution system contained in the frame of the toilet that gives each flush its required ‘oomph’ without wasting a drop. A specially developed distributor sends the water through 3 inlets; water is also flushed into the front area from the left and right, and the frame element has a special inlet connection to supply the distributor. Greenlaunches reports that this saves up to 40% of the total amount of water used in your standard low-flow toilet.

Adding to the appeal of this green ‘WC’ (as the UK manufacturer calls it) is the fact that, like a dual-flush toilet, the Omnia GreenGain comes with an optional economy button can reduce the flushing volume to just 2 liters–a.k.a., around .5 GPF. Which begs the question–how low can you go?
