I had my IC cranking on from the outside faucet a couple months ago... I connect a little sprinkler to the other end to help my grass out a bit... The thing started out just fine, then I came back 10 minutes later and the thing was leaking like crazy. I went on like normal and, hey, it made beer... I bent the top of the copper to hang over my keggle like someone else mention earlier to alleviate the problem for the future.
