Yep. I think it happened from accidentally hooking up a keg that was sealed with 30 PSI to the gas line that was pressurized with 10 or 12 PSI. I don't think I knew it happened. But I took apart my system and found white stuff in the lines and green mold in one of the disconnects. Cleaned 'em up, no issues since. Still get pretty paranoid here and there if my palate is off. I'll start imagining stuff. I got pretty traumatized; lots of ruined beer.After having just gotten over an issue with dirty gas lines, it's better to be safe then sorry.
how did they get dirty on the inside? from beer getting sucked into the line?
Likely getting pushed from a pressurized keg into a non or lower pressurized line. I have check valves on my keg lines to prevent this from happening, to a point I guess. I try to remember to reduce the pressure in my kegs when I'm connecting to them to keep beer/foam out of gas lines all together.
