well the subject line kinda says it all. I didn't keep a good enough eye on the water level and it got too low, so the pump was sucking air. I never checked how hot it gets during normal operation, but it sure was hot! When I realized it I turned it off, filled pool and it seems to be running fine.
However all that made me wonder if there is thermal overload shutoff on the pump so it can't burn out?
thanks and stay cool everybody
