18th Edition Released & Now, UPDATED SEMI-MONTHLY!!!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. None of these, however, use test media that closely resembles the real "demands" upon a toilet, i.e., that of removing 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 MaP 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 (1st Edition - December 2003). That report led to the further evolution of testing and reporting on toilet fixtures and their flush performance.
Now in its EIGHTEENTH EDITION and over 7 years old, the current MaP testing report provides performance information on over 1,500 different toilet fixture models!!! Many of these models are WaterSense-certified high-efficiency toilets (HETs).
Download the MaP Background Report (15 pages) to learn how MaP was developed and read the current full test protocol. Download the PDF listing of 1400+ tank-type toilet fixtures, and their flush performance or the PDF listing of 97+ commercial flushometer valve/bowl combinations.
