Nice day in the shop with the wood stove fired up and a list of service tasks to complete. Every other year I do a 300-hour service on main and kicker. I only put a little over half those hours on, but I believe in extra maintenance as insurance.
That policy paid off when I went to change the impeller on the main. Totally fried; how was this thing still pumping? Obviously the motor was run without water in the pump, but I can't think how or when this would have happened.

I had a water pump repair kit on hand so I did the full replacement. Nothing else untoward found.
