Maximum Performance (MaP) Testing
The Only Measurement of Toilet Flush Performance!
Many toilet fixture performance tests exist, including proprietary tests by the fixture manufacturers, tests by Consumer Reports magazine, and the tests mandated by the plumbing codes for fixture certification. Few of these, however, use test media that closely resembles the real "demands" upon a toilet, i.e., that of human waste.
The Maximum Performance (MaP) testing project was developed in 2003 in order to identify how well popular toilet models perform using a realistic test media. The testing protocol, cooperatively developed by water-efficiency and plumbing fixture specialists in the U.S. and Canada, incorporated the use of soybean paste as a test media, closely replicating the "real world demand" upon fixtures. Performance testing of 80 different toilet fixture models was completed and summarized in the Final Report of December 2003.
Now over nine years old, the current MaP lists provide performance information on over 2,050 different tank-type toilet fixture models and 350 commercial flushometer type fixtures. Over 1,100 are tank-type WaterSense-certified high-efficiency toilets (HETs)!
