Any experiences with Kohler Adair (K-6925)?

Hello.

I am considering this toilet and am having minimal success finding reviews for this model that debuted in 2012. If you have this toilet, I'd like to hear from you.

Thank you.

I don't approve of any ultra-low volume flush toilets (or urinals). 1.28 gpf seems to have dropped the bar too low for any brand. I have had experiences with unclogging drains on homes, especially with cast iron pipes, where I would visit them several times throughout a year. Most people can't afford a repipe of their DWV to accommodate a new low flow toilet. I ask how minimum standards from 20 years ago have changed to properly clear soil from a toilet and leave the surface clean as well as remove the soil from the pipes, to where they are now when most homes in America are older than 20 years. It seems that the desire for greener products is more of a priority than good sanitation. Even with plastic pipe upgrades I make regular visits to a group of properties that just "upgraded" to Kohler 1.28gpf toilets. My 1.6 is as low as I would go. Just my two cents.
