Kohler Co. introduces a new dual-flush toilet line featuring the familiar side-mount trip lever feature, but with a two-piece design that makes it easy to understand the two flushing options. The lever is split into two sections - one for light and one for full flush - and opens up the top space on the lid. Actuating the bottom, or long portion, of the lever provides a 1.1-gallon light flush, and pressing down on the two pieces together provides a 1.6-gallon full flush. The new toilets carry the EPA WaterSense certification and their siphon jet performance is similar to existing 1.28 gpf toilets. The new dual-flush trip lever is available on several Kohler toilet models.
