# This Wellworth dual-flush toilet tank combines water savings with powerful flush performance. An innovative two-tone flush lever offers the choice of 1.1 or 1.6 gal. per flush; the dual-flush lever is located on the side of the tank like a traditional toilet, leaving the top free for storage. The high-efficiency 1.1-gal. flush reduces water use by more than 30 percent over the 1.6-gal. mode, which adds up to potential water savings of more than 4,000 gal. per toilet, per year.
