ALL_MaP_PREMIUM-HET OR (MaP_PREMIUM-HETs-Avail_California) provide superior performance and efficiency for residential or light commercial applications
Qualifying tank-type and electro-hydraulic residential/light commercial toilet fixtures must:
Be certified to WaterSense®
Have an effective flush volume no more than 4.0 litres (1.1 gallons*) – 14% BELOW the current WaterSense® requirement! (With special unique requirements for dual-flush models**)
Have a MaP flush performance score of at least 600 grams – 170% of the current WaterSense® requirement!
**-NOTE: UNLIKE THE U.S. EPA’s WaterSense PROGRAM (AND UNLIKE CALIFORNIA), MaP PREMIUM DOES NOT INCLUDE NOR ALLOW ANY TOILETS WITH A 1.6 GALLON (6 LITRE) FLUSH. Instead, MaP PREMIUM sets the maximum flush volume at 1.28 gallons (4.8 litres) for the full flush on a dual-flush fixture. Single-flush toilets are subject to the 1.1 gallons per flush maximum.

*MaP PREMIUM recognizes that 1.10 gallons is slightly greater than 4.0 litres, however, it is our professional opinion that this difference is not materially significant.
