Flushology: Next Gen Dual Flush Toilet Has True Siphonic FlushBy
H2Option is the first truly siphonic dual flush toilet, with strong push and pull action created by forceful but quiet jetted action under the rim.
Why does that matter? As we learned earlier in Flushology, dual flush toilets do a great job of saving water, and many work great at the toilet’s most important function–getting everything out of the bowl without clogging.
We also learned that dual flush toilets cleanse the bowl with what is known as a washdown flush. Washdowns can create a little unpleasant splash action. You know what I’m talking about.
H2Option adds more push to the water from under the rim of the bowl. We engineered the water pathways so that when the water is released from the tank, some of it is diverted to the rim where there are a series of chambers. The air in the chambers pushes the ongoing coming water forcefully out into the bowl, pressurized, but not mechanized, so it’s a quiet action.
There is no sound associated with the added force; and a lot less splashing. The marketing types call it “Staying Clean While Going Green,” which actually is one of their better headlines. This is the kind of thing we get to invent at the American Standard New Product Design Center.
