The New Drake® Dual Flush Elongated Two-Piece Toilet with High Efficiency Flush (Seat Included) with 10 Inch Rough In and CEFIONTECT 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 1.28 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 TOTO Drake meets the standards for EPA WaterSense®, and California’s CEC and CALGreen requirements. This Drake model comes ready for install into a 10 inch rough-in. The Drake bowl and tank set includes 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.
