The new Drake® 1G® Dual Flush Elongated Two-Piece Toilet with High-Efficiency Flush (Seat Not Included) with is the culmination of enhanced design and functionality. Powerful and durable enough to work within both residential and commercial applications, the new drake exceeds all expectations. Featuring Toto's Dynamax tornado flush, which utilizes a 360-degree cleaning power that reaches every part of the bowl. The enhanced design of the inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. The advanced dual flushing system allows you to proactively conserve water usage by choosing between a 0.8 GPF rinse or 1.0 GPF for tougher jobs. This version of the drake includes Cefiontect, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. Cefiontect coupled with Dynamax tornado flush helps reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The universal height design allows for a more comfortable seat position across a wide range of users. The total drake meets the standards for EPA WaterSense, and California's CEC and Walgreen requirements. This drake model comes ready for installation into a 12" rough-in. The drake bowl and tank set include a toilet seat, tank-to-bowl hardware, a tank-to-bowl gasket, and toilet bolt caps. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, and water supply lines.
