This prevents potential water damage caused by the tank overflowing and indicates to the user that there is a problem by a "constant running" condition. On most toilets, the overflow tube also has a refill tube flowing into it. The refill line directs water from the ballcock through the overflow tube to the bowl after the siphon break.
