Leonard, the installer for our new water heater dropped the old water heater on our cement floor (I heard the crash but he didn't say there was an issue), leaving an approximately 8"x10" divot / smashed area in the floor. He didn't say a word to me about the floor and put the rug back over top so I wouldn't see it when I inspected if before he left. It was only discovered later in the day when walking across the floor and feeling the very definite hole under the rug.
