Relatively new to kegging (4th keg in the 4 tap kegerator) I have been working through "issues" as they have come up. One that has come up that has been slightly worrisome is that the quick disconnects seem to have (every one in awhile) a rather tenuous seal to the posts.
I have all pin lock connections and did the requisite refurb of the posts, etc. when I first set everything up. I did not replace the poppets or the o rings on them, but they all seem to be in good shape and tight when they are inserted in the posts.
I have noted that on occasion the gas posts are rather "sensitive" to being moved as lines were moved around the inside of the kegerator. Moved slightly, you can hear the gas escaping. With a little fidgeting, I can always get the "flow" to stop.
The slightly more troublesome issue I have been having is that the QD for the liquid post on a recent keg seems even more "sensitive". On occasion, it has allowed a flow of beer out from under the QD. Again, a little fidgeting and I can usually get it to stop. I noticed the other day that a flow had occurred when the kegerator was closed over the course of a couple days as dried beer was evident on the side of the keg and around the bottom - sticking it to the floor.
I cleaned that up, took apart the QD, checked, cleaned and sanitized all the parts, and replaced it - being extra careful when I redistributed the lines and closed the door. I made sure the cap plug was well tightened down. Every so often I just crack the door to be sure all is in good order.
My main question/concern is has anyone else experienced the same "sensitivity" with pin lock QDs? And is there anything I should be doing different? Is this something inherent with pin locks?
A lot of beer has not been wasted to this point - nor gas (as far as I can tell). But it is worrisome that I can't just close the door and forget about it. It doesn't seem like the QDs should be that sensitive.
