The TOTO® Drake® 1.28 GPF toilet tank with WASHLET®+ auto flush compatibility is designed for use with compatible Drake® bowls. Compatible Drake® bowls feature TOTO's TORNADO FLUSH®, a rimless, hole-free design with dual nozzles that create a centrifugal washing action that assists in rinsing the bowl more efficiently. This version of the tank comes equipped with a left-hand chrome trip lever. This Drake® tank meets the standards for EPA WaterSense® and California’s CEC and CALGreen requirements. The Drake® tank includes a tank-to-bowl gasket, tank-to-bowl hardware, and toilet bolt caps. Additional items needed for installation and use must be purchased separately: compatible Drake® toilet bowl, wax ring, toilet mounting bolts, water supply lines, and toilet seat.
