I scoped out the study and commissioned it because of concern over the long-term performance reliability of the 6-liter toilets. This concern grew out of frustration with the ASME A112.19.6 committee on toilet performance standards, and concerns about whether we could bank on reductions in toilet water use based on what appeared to be rather iffy short cuts taken by manufacturers in producing toilets that comply with that standard. At one time, I was the water industry's representative on that ASME panel; my name is on the committee list for the 1990 publication of that standard.
