Anyone ever visit this website? http://www.cuwcc.org/MaPTesting.aspx Aside from being very informative I think it would be a great selling tool for you plumbing professionals. Here in Connecticut, there still are a great number of first generation low flow toilets, the ones with narrow unglazed trapways. The kind you generally have to flush twice thereby negating the benefits of the 1.6 gallon Federally mandated fixtures. They (CUWCC) do real world tests on all makes and models of toilets, are unsponsered and appear to be unbiased in their appraisals. Forgive me if this has been posted before, I'm pretty new to the site but I sure do enjoy your company.
