There also are times when toilets can leak. To check for leakage, put a few drops of food coloring in the tank. Wait a few minutes, then check the toilet bowl. If you see the food coloring, then there is a leak which should be fixed. It is a good idea to check for leaks about once a year.
Many people think taking a bath conserves more water than showering.
To check your shower usage, close the drain when you shower. If the water fills up to a higher level than your normal bath level, then taking a bath is the better option. If you prefer to take showers you can check how fast your showerhead is using water. In order to do this, you need a bucket and a watch that measures seconds. Mark the bucket at the one-gallon level.
