MaP PREMIUM
Some fixtures are “high performance”.
Some fixtures are “high efficiency”.
MaP PREMIUM is BOTH!!
Last Updated: August 14, 2024
ALL_MaP_PREMIUM-HETs provide superior performance and efficiency for residential or light commercial applications where water discharged from other fixtures, appliances, or processes, etc., near the toilet fixture can help transport waste through the drain pipes.
Qualifying tank-type residential/light commercial toilet fixtures must:
- Be certified to WaterSense®
- Have an effective flush volume no more than 4.0 litres (1.10 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!
- WaterSense allows 1.6 gallon (6.0 litre) dual-flush toilets – NOTE: MaP PREMIUM DOES NOT INCLUDE 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.8
