The All-in-One elongated version of the dual-flush, 1000 Gram HET toilet is WaterSense certified and uses 1.1 gallons of water for liquids and 1.6 gallons for solids, saving up to 16,000 gallons of water per year for a family of four versus 3.5-gpf models, the company claims. The company’s patented power-assisted flush system uses water to compress air and remove the maximum amount of solid waste. Antimicrobial protection is built into the toilet seat. 800.443.1410. www.foremostgroups.com.
