Low flush toilets?? Research??

[Master ACiD]

a buddy of mine has been working for palm beach country waste management for a number of years now. he was involved in testing different brands of low flush toilets for use in city buildings.

what he told me was that the american standard and kohler toilets performed the best. so much so that he put AS toilets in his own house. now i dont know which models were best but those are the 2 brands he said worked best.

he also said the number 1 toilet related problem he finds is people trying to push the flush handle with their foot and breaking it or the toilet resivour that its attached too.

For any of these low flush units to work properly, the pipes under them have to be right for the unit you are installing.
Old pipes may be to big diameter; the low flush types call for smaller pipes to keep the syphon action working properly.

The new Kohler works fine on my 60 year old pipes.

As to the original question/complaint, I'd just note that a number of water management districts are encouraging their customers to switch, even offering rebates. I'll defer to their knowledge and experience on this.

Here's a humorous entry from the 2004 CA Science Fair that
involved using Hostess Ho-Ho's to simulate solid waste:

58% savings even with more double flushing. Must have been
a low-grade low-flow toilet.
