I own three Perlick faucets. I love Perls, they are great! However I've developed a problem with one. A few weeks ago it began leaking from item number 7 in this diagram.
So, I took it apart and traced it to a cut gasket -number 2. Last week, I got my new gasket in, tightened it back down, attached it to the shank, and it still leaks from the same spot! I tried tightening down on it more, it's really tight. Then I check my other two faucets, all the fittings are just hand tightened and they haven't leaked for 2 years. I'm kinda dumbfounded by this one. Perhaps number 6a in the diagram has gone bad? It doesn't look damaged...
