Have you ever heard your Kohler® toilet start running without flushing? That means your flush valve seal is leaking, causing the fill valve to turn on. Over time, rubber can wear out which is what causes the running toilet. It's recommended to replace your seal every 5 years to make sure your toilet isn't leaking nad inflating your water bill. This simple DIY project only takes a few minutes to do. We recommend getting a Korky 2X Long-Life Fits Kohler® Seal - it's made of a 2X stronger material and is backed by a 10-year warranty.
