Are you like me and don't know the first thing about plumbing repairs? There are so many different types of them, and there are so many warning signs to look for. If you don't know the warning signs, you can end up with a plumbing disaster on your hands.
One time, I just happened to notice the very corner of the wall was wet and looked different. It was because of a very small leak in the copper piping leading to my bathtub. I had to get it repaired before it became a much bigger problem.
