If I shut the pump off for a while, like overnight, or 10 hours during the day, when I turn it back on I get a loud squeal that lasts from 45 minutes to an hour or so. The water seems to be pumping OK, and the pump pressure is good and in the normal range. It seems to me that once the pump gets hot that it quits.
Is it the pump motor itself that's going bad, or do you think it might be in the pump itself? I can't isolate the noise to either one.
Also, I might have a small leak somewhere in the pump/motor area as the pad under the pump/motor is always very damp. I can't find any visible droplets though.
