Is there a way to diagnose if the shaft/impeller is the cause or the pump itself is busted? I hate to spent $30 for a new impeller and come to find out the pump itself is busted....I know the shaft on the impeller is pretty beat up. How can I tell if the pump itself is still good?
Forgotten: the pump is Resun King-590F
