Yeah you need a better name for that, because, while the phenomenon is real, the name is kind of meh. Why not the electrician problem? Or the teacher problem? Any profession would work. Why plumbers? Plus, I can't really recall any movie or novel where expertise in plumbing was essential to the plot.
Editing here because based on some replies my message wasn't clear: I was talking about expertise in plumbing exhibited by one of the protagonists, not someone watching the movie obviously.
