The Department of Water and Sewerage reminds its customers that toilet leaks waste hundreds of gallons of water each day.
The good news is that toilet leaks are easy to diagnose and fix. Simply put a few drops of food coloring in the tank and wait 10 to 15 minutes. If the water in the bowl is colored, you have a leak. Most toilet leaks are the result of deteriorated flappers and outflow tubes that are simple and inexpensive to repair.
Also, remember unnecessary flushes can waste up to five gallons of water per flush. Don't use your toilet for a trash can.
