Re: After Winterizing: Fire Up and Go?
I've heard the stories of impellers lasting several years too. They might.
But a failure is more than pulling over and replacing it. The bits and pieces can end up causing blockages downstream in the heat exchanger. In the worst case scenario, they can't be disassembled to clean out.
Impellers are relatively inexpensive, therefore, why take the chance. Cracks are obvious, but impending failures scenarios are not all driven by cracks.
I've had one fail three hours out of the box.
