Re: Premature impeller failure cause

Seems like a false economy to use a smaller pump at higher speed, but I'll leave that to the experts. If the smaller pump is turning faster it's entirely possible that the small supply hose is part of the problem but if the pump was starving for water (vacuum) I would expect to see vane problems similar to running dry.
