Niagara Conservation’s Power One pressure-assist toilet meets both the criteria of the EPA WaterSense program and HET rebate standards. The Power One is a 1.0-gpf toilet and can save up to 18,000 gal. of water per year if it replaces an old 3.5-gpf toilet. The toilet uses Sloan’s Flushmate pressure-assist flush system for a quieter flush. Its 10 3/4” by 20 3/4” footprint is ideal for retrofits and remodels because it covers floor exposure after installation.
