If the inside tank looks like this, there are no parts.
The seals on the tank resrevoir seem to have broken or seperated, causing the toilet to overflow. Have any of you heard of this? Should I replace the toilet or are their repair parts available. The toilet is about 10 years old. I also don't know whey the overflow did not stop this from flooding????
It looks like the black cannister (reservoir?) cracked. Have other people had this problem? Is Kohler offering any credits or something???
