- Check all faucets and piping for leaks by monitoring for drips of water under sinks and from exposed pipes.
- 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.
- Use the water meter as a guide. Make sure all water using appliances are turned off, read the water meter, wait 10 to 15 minutes and read the water meter again. If the meter has moved at all there may be a leak.
- 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.
