The TOTO(R) Drake(R) 1.28 GPF Toilet Tank with Right-Hand Trip Lever is designed for use with compatible Drake bowls. Compatible Drake bowls feature TOTO's TORNADO FLUSH(R), a rimless, hole-free design with dual-nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. This version of the tank comes equipped with a right-hand chrome trip lever. This Drake tank meets the standards for EPA WaterSense(R), 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.
