MaP Testing

March 2013
MaP in its 10th Year!

Just what is MaP, anyway???  Maximum Performance (MaP) Testing originated in 2003 with a industry-changing report on toilet fixture flush performance.  Since then, products from the plumbing industry have improved dramatically 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 and MaP-approved laboratories in North America and Asia.  MaP takes the test results (good or bad) and reports them on  

A special thank you goes to the 22 water utility interests in the U.S. and Canada that sponsored the original development of the MaP testing protocol.
