I just got my first keg, it was pressurized at the store. I open it up, dump hot soapy water in it, close up the lid to shake it and water comes out. I thought the lid was perfectly sealed and double checked it. I was planning on letting a beer carbonate with priming sugar in it tonight but now I need to know beforehand that it is totally sealed. I'm not worried about it being deffective, just a user error.
