Toilet testing February 10, 2008

Titled Maximum Performance, and abbreviated as MaP, engineers William Gauley and John Koeller have systematically tested over 600 toilets since 2003. While the sheer number of test subjects is astounding, so are two other facts: the co-authors live in Ontario, Canada and California, and the testing was done using very realistic soy-based test media.

Gauley and Koeller appear to be concerned with the occasional customer dissatisfaction with newer low-flow toilets. They are out to identify, in their words the "bad apples;" the toilets that require multiple flushes for solid waste. (Here enters the soy-based test media. Viewer beware, this is either disgusting or hilarious depending on your point of view.)

All giggling aside, the most recent edition of their report is absolutely comprehensive. The appendices to the report list line by line the toilets that do and do not meet the 350 gram test threshold.
