Sometimes it's difficult to tell if your toilet is leaking. Did you know that a "running" toilet can waste up to two gallons of water per minute? That's wasting up to 7,000 gallons of water a month! There's a quick and easy way to check for a slow leak. Add food coloring to your tank, wait 30 minutes to an hour, and if you see color in the toilet bowl, you have a leak. Usually leaks in the toilet are caused by a defective flush valve. By replacing gaskets, flapper valve or other worn parts in your toilet you can keep your toilet happy and save water.
