Why does my Kohler toilet run periodically?

If your toilet frequently turns on and off for a short period of time, it is probably because of a faulty flapper. The flapper is designed to close the tank after enough water has passed through, but if it is cracked or deteriorating, it won’t seal properly, causing water to continuously flow through and leading to intermittent running. This issue can waste water and increase your water bill.
