A quick and easy way to see if your toilet is constantly running is to simply remove the tank cover and add a few drops of food coloring. Without flushing, approximately wait 15 to 30 minutes, if the food coloring reaches the toilet bowl, your toilet is constantly running. Pending on how bad your toilet is running, it can waste .5 to 6 gallons of water per minute (an average new toilet uses just 1.6 gallons per flush). That can add up to thousands of gallons of natural, and financial, resources down the drain.
