Sloan Valve introduces its new 1.1-gpf toilet systems, which combine a vitreous china toilet fixture with either a manual or sensor-operated high-efficiency 1.1-gpf flushometer. These new toilet systems use 14% less water than the company’s current lowest combinations at 1.28 gpf and 31% less than the 1.6-gpf EPA standard. Sloan offers three water-efficient flushometer options: Royal manual valves, and ECOS and SOLIS electronic valves — all paired with Sloan floor-mount ADA and wall-hung bowls for a total of nine different combinations.
