All those who have a Kohler Sink or Faucet make sure you take advantage of Kohler's awesome replacement service. They will usually replace a broken part even after the warranty is up. I've done this a couple of times. The last time I called customer service it was concerning an old Kohler Faucet in a home we just purchased. I called customer service at Kohler and they offered to send the replacement part for free. Not only that they shipped it for free too. So before you go buying those parts check with Kohler first... it mays save you some money.
