Ok, so I just moved to kegging after several years of bottling. The kegs came from an Internet merchant who shall remain nameless. They clearly came right off the soda truck, which is cool, they were pretty cheap.
Anyway, both are ball locks, although the posts look different, so I don't think I can just swap them between kegs to solve my problem.
All the seals seem fine, until I attach the "beer out" line. Then I get a serious leakage. Like instant puddle. I'm pretty sure I'm attached the connector correctly. I've read enough threads on that to know how it needs to sit all the way down.
My question now is what are the likeliest problems here. The o-rings aren't new, but they really didn't seem to be in bad shape. I'm going to order some new ones to replace what I have, but that'll take a couple days. Could the post itself be bad? The poppit inside? What should I be looking to replace?
While you chew on that, I'm going to go hook the other keg up and run some star san threw the system again. Then I'll at least be able to rule out anything non-keg as the problem.
