How can I tell if I have a leaking pipe?

The first step is to check for any visible signs of water leakage. Look for wet spots on the walls or floor, and listen for dripping noises coming from the pipe. If you see any of these signs, you should contact a plumber right away. You can also test the pipe by pouring a few drops of food coloring into it. If the color appears in your sink, toilet, or other fixtures, then there is likely a leak.
