Maximum Performance (MaP) Testing
A better measurement of toilet 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 undertaken 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 in its 13th edition, the current MaP testing report provides performance information on over 842 different toilet fixture models. Many of these models are WaterSense-rated high-efficiency toilets (HETs).

If only an abbreviated version is needed to take with you to your favorite retailer or plumbing supply house then download the Condensed MaP Report, which contains the most essential information including data on all toilet fixtures, but is shorter and easy to print (black & white only) and read.
Additionally, appendicies that list toilet fixtures sorted by different criteria are available for separate download.
