Unique Issue Resolved

Would Recommend

In replacing an old valve, I first tried two different general units, as I've done successfully multiple dozens of times before, but both valves leaked in this Kohler toilet. This valve worked fine.

Still noisy

Still loud intermittent 'hissing" when tank is filling. I have cleaned the cap and bled the part several times. Still has made no difference. Other toilet tanks in the house dont have this issue. Disappointed in the product. Expected more from Kohler genuine parts.
