So, I finally sprung to refurb my kegerator with Perlicks and barrier tubing. I've got a 3-faucet setup, and one of my Perlicks is kinda binding up. Opening and closing the faucet has a metal-on-metal crunchy feel to it. Took it apart, and sure enough the "upper" ball on the control stalk (the pivot ball, not the closure one) has a scuff mark on the side where it's wearing against the main part of the faucet. Lots of swarf too, really don't want metal bits in my beer.
So, is this something that needs to be returned? Or did I goon something up when I put the faucets back together after their initial cleaning? The other two work just fine.
