Sloan Valve Company, a leading manufacturer of commercial plumbing systems, has developed new 1.1-gpf toilet systems, combining a vitreous china toilet fixture with either a manual or sensor-operated, high-efficiency, 1.1-gpf flushometer. The new combinations provide consistent, reliable performance designed to help architects, engineers, contractors and building owners lower water usage while maintaining performance expectations. In addition, the new systems use 14 percent less water than the company’s current lowest combinations at 1.28 gpf, and less than the 1.6-gpf EPA standard.
