Yup, it does just what it's supposed to do. The old one leaked, the new one doesn't. Mission accomplished.

For many years, I've purchased Kohler products exclusively. While they typically were more expensive, the quality was worth the extra money. I've noticed as of late that Kohler is outsourcing more of their manufacturing to China and with that, a degradation in quality. This flapper is just such.
We have 5 bathrooms in our home, with a mix of different Kohler toilets. For years no problem, until the cleaning gals began utilizing Clorox toilet tank cleaner tablets. They caused the flappers to deteriorate and, in turn, leak.
Being a loyal Kohler customer, I purchased Kohler replacement flappers for all 5 of the bathrooms from our local Home Depot. As this replacement flapper was a different design from the original, I could not match it up with the original. This meant a trail and error process for setting the flapper float, which controls the volume of water per flush. Adjusting the float requires removing the flapper assembly each time. This is because the float retainers (one on top and one on the bottom of the float) are clipped into the flapper ball chain and require a screwdriver or similar tool to press them from the chain.
The float position was dramatically different than the original flapper float, so this required many trial and error changes to achieve the proper position. A rather time consuming and tedious process, but I finally achieved the optimum flush volume.
Fast forward six months and I'm making the bed up after having an overnight guest in a bedroom with a private bathroom which we seldom utilize. I'm hearing the toilet fill about every 3 minutes. The flapper I just replaced six months ago is leaking--severely. I turn off the fill supply for the other four toilets and within 2 hours, two others tanks were empty (leaking, also).
I contacted Kohler's support number and told them they had a flapper problem. After discussion, they had concluded the Clorox tablets had also caused the flush valve gasket to deteriorate and it was likely the source of the leak, not the six month old flappers.
I'd ordered new gaskets, but wasn't relishing the prospect of replacing them, as it would require removal of the tank and that would likely lead to more issues with twisted off tank bolts, supply lines and so forth. So before I got into that, I wanted to make sure.
I removed the flapper from the leaking tank and inspected. It was warped. Which would explain why it was leaking. More fine China quality.
I began to look at aftermarket flappers. My research found the "Korky" brand flappers had great reviews, recommended by Clorox for their resistance to their cleaning tablets (which we had ceased utilizing) and were made in the USA. Not to mention they were near 30% less than the Kohler made in China flapper. So I tried them on the leaking toilets.
First, the float adjustment can be made without removing the flapper assembly. The Korky flapper has a linked chain rather than a ball chain. It is designed so the float can slid up/down the chain links and does not have retainers that require removal to adjust. I had the float position optimized in minutes, rather than the hour plus I had spent with the Kohler flapper.
Best of all, none of the toilets leaked after replacing the six month old Kohler flappers with Korky flappers. So I didn't have to replace the flush valve gasket.
