The new Drake® Dual Flush Elongated Two-Piece Toilet with High-Efficiency Flush (Seat Not Included) 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° 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.
