Ugggghhh...here I am again. Without going into the lengthy process of what I've had to do for the last week, let me just get to the point/question.... the screw in the motor that attaches to the shaft will not stay screwed in therefore causing it to lose prime. I have had capacitor issues again this week leading me to this and have those resolved and now I can't get the screw to stay tight. I have used the removeable thread lock as well as the permanent. The pump will start to prime and then all of a sudden will stop. The motor will still hum, it just doesn't keep prime. The pool has been down for a week now and is starting to get cloudy. I REALLY don't want to have to fight a green pool. Is it time to get a new pump and be done with it? This one is only 2 1/2 years old.
