Hey Guys... Tonight the one of the leaf loaders went down.. I've never replaced the/a impeller (its maybe 5 years old... Maybe more?) But it was sucking fine, then all a sudden it just stopped sucking. We shook the hose, thinking it was clogged- but it wasn't. Took the chute off and theres nothing in there! Is it the impeller? Am I missing something? Hoping this has happened to someone else before... I'm dropping it off in the morning but it'd be nice to know ahead of time, if possible.
