Good morning! My pentair booster pump has been making a loud noise for quite some time now. I asked a tech at my local pool store about it and he said it might be the bearings and that it's ok to keep running it, but that it will eventually need replacing. My question: Is this a fairly simple DIY? Is this a repair job or would I be better off replacing the whole booster pump? I think the booster pump just runs our pool sweep (polaris 280). It only makes the loud noise when the pool sweep is going so I'm guessing that's the only thing its for as I don't hear it when we have the spillway turned on, and the waterfall has it's own motor.
