Question: How do you get water to stop filling up the toilet tank?

Answer:

The fill valve in the tank has a leak in it. Also, if the fill valve has been replaced recently it is possible that it has been set too high. If the fill valve is old, it could do you no harm to replace it. Sometimes the shaft or wire that is used to set the level, corrodes off. By replacing it your problem should be fixed.
