I inspect mine in the fall as part of my winterization process. This past winter I saw cracks in the rubber at the base of the vanes so i replaced it. Since I motor about 50 hours a year, I figure I can easily get 4 -5 years from an impeller.
The impeller for my oberdorfer pump is about $50 by the time you add shipping and tax, so I feel that it would be needlessly expensive to change it every year.
I do carry spares with me, so I can change it if required.
