Start by checking for a toilet leak. Do this test at night or when you are out of the home for several hours. Color the water in the tank of the toilet with food coloring, coffee, cola etc. First thing in the morning or when you arrive home (before water is used) check the bowl of the toilet. If the color shows in the bowl, you have a toilet leak. Do this test to all of the toilets in the home.
If you do not find a problem with the toilets in your home, you may have a service line leak. Please contact our customer service staff at 412-741-9180 for further assistance.
