As a designer or specifier, how do I know what toilet fixture will perform? What type of fixture does my client or customer need? Finally, what toilet should I specify? All questions asked by the design professional as the plans and specifications are developed. (Or, at least, they should be asked!)
Whether for a home, business or institutional building, toilet fixtures can be the one item that either annoys contractors (call-backs) and facilities managers (maintenance requests) or gives total peace of mind by functioning to everyone’s satisfaction.
Nearly everyone in North America has likely experienced some degree of dissatisfaction with some toilet fixtures of early 1990s. Clogging, double-flushing, and generally poor flush performance characterized some of the early 1.6-gallon/6.0-Litre fixture . . . and that “reputation” seems to still remain with some consumers.
In direct response to these issues of the 1990s, the water utility industry took a groundbreaking step in 2002 by first stating: “We can no longer encourage our customers to replace their old water wasting toilets with new ultra-low-flush toilets, nor should we be subsidizing (with rebates) product that doesn’t work satisfactorily!” 22 organizations in the water utility industry stepped forward and funded the development of a more rigorous test protocol, which ultimately became known as Maximum Performance (MaP) testing.
Designers and specifiers have the opportunity to review the performance of nearly 2,500 DIFFERENT TANK-TYPE toilet fixture models, all of which have been tested at independent laboratories. In addition, over 370 FLUSHOMETER VALVE/BOWL combinations have been MaP tested as well.

NEW LISTING!! Toilets designed for children and juveniles.
Designing or equipping a day care center? A preschool, kindergarten, or primary facility and need 'child-sized' water closets? This listing includes both gravity-fed, tank-type toilets as well as bowls for flushometer applications. Bowl heights range from 10 inches (254mm) to 14 inches (356mm). (Note that adult-sized conventional height bowls and ADA-classified bowls generally range from 15 to 17 inches, or 380mm to 430mm) Go here to download the listing >>
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). The competitive pressure to improve fixture performance from the unacceptable levels of the early 1990s, together with MaP as a vehicle to measure performance, has resulted in many hundreds of very high-performance 21st century models, for which the manufacturers must be given great credit!

The charts below indicate the performance improvements achieved in the 5-year 2003-2008 period.
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, since 2003, over 3,400 different toilet models have been tested, 2,900 of which are reported in the two public databases on this website!
