I purchased 4 pin lock kegs. At the time of purchase 2 were under pressure for at least 5 years, the other 2 were not. I have soaked them in Oxy for a week and was planning on cleaning tonight. However, when I placed all of them on their side with our pressure they leaked, ever so slightly from the main fill opening. My question; is this normal or do I need to examine the kegs more and find out why they leak. I replaced the main fill O ring on all of them and have not pulled the posts out yet since I am waiting for the socket to arrive.
I am thinking since they 'trickel' it might be normal and if I apply pressure it will be fine since that would apply pressure against the O ring. Thanks in advance.
