How to check for water leaks in toilets?

Are you annoyed with high water bills? And there is nothing more annoying than a leak you can't identify that easily, one of them is the leak from the toilet tank and bowl. An unfixed toilet leak can waste more than 10,000 gallons of water in a year, enough water to do laundry for 10 months, according to Environmental Protection Agency (EPA). But luckily there is a quick fix to solve this toilet leak problem.


Stephanie Thorton, a representative from EPA's Water Sense program, gives the following tip:

1. Put a few drops of food coloring (I used yellow coloring substance) in your toilet tank.
2. Check back after 15 minutes and if the color has seeped in, you have a leak.

I tested it in my home and it works as advertised, thankfully there is no leak for now.
