Default Kohler Toilet Flush Canister Twisting

This subject was covered in an earlier, closed thread but I’m certain that it’s still relevant to many homeowners in TV. When you flush a Kohler toilet with the canister type flush valve, the canister twists and does not seat properly. It’s been suggested that replacing the gasket with the yellow Kohler genuine part GP1059291 Canister Seal $6.90 on Amazon or any of the big box stores might fix the problem.

Well I tried it and one month later can tell you that it does fix this problem. Why? I suspect that the new rubber seal prevents slippage that allowed the canister to twist. There’s no other explanation. But many thanks to the earlier contributors on this site who shared the fix. It was a very annoying issue.
