:138 Low Flow Toilets

1:5:10:138 EcoTip: California researchers import fake poo from Canada to test low flow toilets.

 Source: MaP 11th edition

The ongoing research project, identified as MaP (Maximum Performance Testing of Popular Toilet Models) is now in its 11th edition. In spite of the joke potential the published results provide excellent information for the excrementally endowed. If you find your low flow toilet requires more than one flush – This is the place to look for toilets that can handle up to 1000 grams at a time. According to a British medical study (Variability of Colonic Function in Healthy Subjects) the average maximum male dooty is 250g.

We developed the Maximum Performance (MaP) testing to identify how well popular toilets models perform bulk removal using a realistic test media, and to grade each toilet model based on this performance. A soybean paste having similar physical properties (density, moisture content) to human waste was used in combination with toilet paper as the test media. In addition to using a realistic test media, all toilet samples are adjusted, where possible, to their rated flush volume (typically 6 litres / 1.6 gallons) prior to testing to ensure a level playing field.


Additional Information

The research project results can be reviewed at: http://www.cuwcc.org/MapTesting.lasso 

The fake excrement is a Canadian Soybean paste with a density and moisture content similar to human waste. It is extruded through a 7/8-inch diameter die and shaped so each flushable is approximately four inches long and weighs 50 grams and is encased in a sausage-like latex coating so it is reusable.
