Faucets – Check all faucets and piping for leaks by monitoring for drips of water under sinks and from exposed pipes. Perform an inspection with the water on and off, as some leaks only occur when the water is on.
Toilets – Add a few drops of food coloring in the toilet tank. If the food coloring appears in the toilet bowl, this means you have a leak. Some toilet leaks are intermittent, so you don’t always see or hear the water running. Check plumbing in the basement by monitoring for drips of water coming from exposed pipes. Occasionally, leaks develop behind walls or in areas that are not visible. Read your meter periodically to monitor for drastic changes.
Your meter is usually located in the basement. On your meter face is a red or blue triangle. If no water is being used, your triangle will be still. If the small triangle is rotating, then water is being drawn from somewhere in your building.
