Some fixtures are "high performance".
Some fixtures are "high efficiency".
MaP PREMIUM is BOTH!!
Last Updated: March 31, 2022
MaP PREMIUM-rated plumbing products 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!
*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.
