Hey all, when I recently got back into brewing, I completely tore down my keezer, replaced all lines, and dismantled my Perlicks to soak and scrub. When I did, I didn't isolate each tap's parts, i.e they were all mixed together. They are all the same model, so I can't imagine that is an issue. Once I got them back together and in use, a few of them feel a little "rough" when opening/closing. Any ideas?
