Joe came to the house on time. Did a lot of investigating about the clicking in the wall when the hot water was ran in my kitchen and bathroom.
End result, nothing was wrong with the pipe (Thank God!) and it had to do with the drain and the sewer vent.
I had my roof shingled this past summer and the sewer vent shifted. So when the hot water is run in my kitchen or bathroom, the drain pipe expands and bumps into the sewer vent pipe. I still have clicking, but at least I know what is going on now.
Joe is always super professional and kind. Explains things that I can understand, but he NEVER let's me feel like I am dumb.
I refer everyone I know, if they need a plumber, to contact Ben Franklin. :)
