MaP now in its 10th Year!

Maximum Performance (MaP) Testing originated in 2003 with a industry-changing report on toilet fixture flush performance. Since then, products have improved and, today, over 80 manufacturers and 100 brands of plumbing products are a part of the growing MaP program.  These manufacturers submit their products for testing to one of 7 independent (accredited) and approved laboratories in North America and Asia.  MaP freely publishes the test results (good or bad)!
