Fix a Leaky Toilet
If you are the family handyman, here's a handy trick to prevent wasted water from a leaky toilet. First, remove the lid from the tank and add a few drops of food dye or even a packet of kool-aid (or other powder drink mix).
Then, open up the lid and observe the water in the bowl. If you notice the water in the bowl changing color, it's a sign of a leak, most likely from the flapper inside.
Go ahead and replace the flapper, and you'll not only fix the leak but also save water, which will eventually offset the cost of the new flapper.
