I opened up the pool and started the cleanup process. The main pump, Hayward super pump 0.75 HP is making a loud noise. I replaced the motor with a quality motor two years ago, so I think the noise is coming from the pump side as opposed to the motor. A new pump now goes for $700, as compared to the $350 I paid for it 10 years ago. I will start calling around Monday morning to try to find a repair person, but I'd be appreciative of any advice regarding this kind of repair.
