Review on 🚽 Essential Values 3 PACK Flush Valve Seal: Replacement for K-GP1059291 Models in Kohler Toilets by Payton Luna

The toilet ran because the drain valve would not close. The old gasket didn't look too bad to cause a problem. But I replaced the gasket and cheers! Problem solved, the seal is very easy to replace. It only took about 5 minutes. Anyone could do it. But how to do this is not necessarily obvious. It has a few YouTube videos in it, so search "replace the Kohler canister purge valve gasket" or something. $7.80 seems a bit expensive for 3 rubber pads, but considering the shipping it's not bad.
