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.
TIP: You'll want to flush immediately after testing to avoid staining your toilet tank.
A running toilet can waste up to 200 gallons of water every day, sometimes more. This can add $500 to a single water bill. 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.
It's typically best to replace the entire rubber flapper as it's inexpensive and easy. They usually pay for themself in water savings in a relatively short amount of time.
