High Water Usage
A noticeable increase in water consumption could be an indication of a water leak in your home. One of the most common leaks are from toilets. Toilet leaks can waste hundreds of gallons of water per day. Even though a toilet isn't running, it can still be leaking water. If you suspect a problem, add food coloring to the water in the tank. After several minutes, if the water in the bowl begins to turn color, there is a leak. Also, look inside the tank for water going into the overflow tube. If a problem is identified, contact a plumber to make repairs.
