Water leak in the toilet tank prevents the full tank from remaining for a long time. As the float ball inside the tank lowers, the fill valve compensates by removing more water. According to the Environmental Protection Agency, a constant hygienic leak can lose up to 200 gallons of water each day. Water that is lost is money lost. Fixing the leak requires first locating its source. The use of food coloring in the tank determines if the leak originates somewhere in the tank.
