I was just looking at mine yesterday and wondering the same thing. I bead blasted it and it looks like the tabs will have to be bent back to dissasemble it. I guess the rubber washer or valve is in the copper inlet and outlet tube. I tried the search to see if anyone had posted anything on this but did not find anything about actually rebuilding one. I guess one of us is just going to have to jump in and do it Woody.
