Toilet water does not stop running
My Kohler toilet was running and I replaced the valve ball however, the original part supplied has a foam part connected to the chain and this replacement does not have it b/c it is not made by Kohler. I turned the water back on and it is going over the water line inside the tank and does not stop. Is it necessary to use the same type which was supplied by Kohler or what else should I be doing so that it is functional again in order to remedy this problem? This is the first time this has happened. I am a female so thought that I could fix it myself, is that a mistake??? Help if you can give me advice, please.
