Review: This is the same valve as Kohler 1095687-SC - The difference is that the Kohler 1095687-SC is a kit and includes other parts besides the valve like the actuator button and the valve seat in which this valve clips on. The seat usually lasts a lot longer than the valve. The other thing to know is that Kohler one comes already set for the Escale toilets while this valve needs to be adjusted. It is easy. Just search for the instructions on Kohler web site/YouTube. This valve comes with no instructions. But before replacing the valve make sure the issue is not the valve seal. The seal is cheap $5. Kohler part number 1021424, replaced by 1131496.
Review: Fixed the tank leaking into the bowl. - Since the original flush valve was the same, it was a very quick replacement. Solved the issue of the old flush valve leaking into the toilet bowl.
