We often don't think about the plumbing in our homes until something goes wrong. A leak, if untreated or undetected, can lead to serious damage and costly repairs.
Angie Hicks, the creator of Angie's List, said "Easy signs of leaks in your house could be the fact that you have stains on your walls, if you have wallpaper that's buckling, or even a wooden floor that's buckling, or if you just smell a musty smell you need to have that investigated."
To spot a leaky toilet, place a few drop of food coloring into the toilet tank, and wait 15 minutes. If the food coloring has entered the toilet bowl without being flushed, you have a leak.
Another way to test your toilet is to place a few sheets of toilet paper at the base of the toilet and flush. If there is the slightest leak, the toilet will drip water onto the toilet paper.
