The rubber cone joint on a toilet allows the toilet to keep the water inside the tank. Over the course of a couple years the rubber cone can become cracked and withered. When this happens, you will find water leaking from the toilet onto the floor. Water damage to a bathroom can be a very costly expense when not handled in a timely fashion. Replacing this rubber cone will eliminate the chances of having water ruin your floor.
