Recently, new HET models have come to market that use 4 Liters (1.06 gal) or less to flush, and are also USEPA WaterSense certified. At this time, the incentive will be available for ONLY multi-family installations. Rebates for standard toilets, which flush at 1.6 gallons, are not available. Four liter toilets must be replacing an existing 1.6 gpf or higher toilet (not replacing an existing 1.28 gpf toilet).
High-efficiency toilet rebates must have a matching bowl and tank or matching bowl and flushometer valve. Modification of existing valves or use of valve kits does not qualify for a rebate. Rebates vary by water agency and are subject to change.
