I used a compression fitting in my wort chiller when I first built it, and all the heating, cooling and moving around caused it to loosen and seep water into the beer. This wouldn't be so bad on a municipal water supply, but I use raw lake water to cool. I don't think I got an infection but I did drink that batch fairly quick.
