They went to the cannister because the extra large flapper they were using became too soft and would leak.
I asked the head engineer at Kohler why they were going so big, I suggested that 2.75" may be better, it would still drop plenty of water quickly, and be easier to design a flapper that held up.
The president of the company chimed in and said that for marketing purposes, bigger is always better.
I disagreed, but then what do I know.
The Keg Restaurant in Factoria.
It would be a simple fix to come up with a replacement flush valve with smaller opening and flapper.
A/S came up with a replacement for their Champion line.
They went big for marketing too, but it necks down to 3" so all that hype was really marketing again.
The meal was good and the company. Jamie and I enjoyed talking with them. Both very nice people.
I love the Kohler cast iron tubs. I need to install one here.
The Mendota K-506 is a really nice one.

Though I did install the Archer for someone, and that would work too.
