Maximum Performance (MaP)

About MaP

Since its development and release in 2003, MaP has been a major driving force in the improvement of toilet flush performance in North America. In 2003, the average MaP score of all tested toilets was about 350 grams (12 ounces), while by August 2008, the average score of 746 different toilet fixture models had nearly doubled to about 675 grams (24 ounces). (SEE THE GRAPHICS HERE!) The competitive pressure to improve fixture performance from the unacceptable levels of the 1990s, together with MaP as a vehicle to measure performance, has resulted in many hundreds of high-performance 21^st century models, for which the manufacturers must be given great credit!

Remember, though, MaP is a VOLUNTARY testing program. Manufacturers may choose to participate, but are under no compulsion to do so. Therefore, not all toilet models found in the marketplace (at the wholesalers, distributors, retail outlets, plumbing supply houses) will have been MaP tested. But, to date, 2,000 different toilet models have been tested, 1,800 of which are reported in the public database on this website!
