Found this moka pot at a friend's relative's house, they said it's been in their family for a bit over a decade. It just broke about a week ago, but it seems like it means a lot to them. Unfortunately they're a little too old to check out how to get it fixed, so I'm thinking of doing it for them in the near future just as a gesture.

Question is, is it possible? If so, what needs to be done/replaced?
