I recently replaced my pump motor since the other motors bearings were wearing out and making a lout squealing noice. Once I installed it it was so nice and quiet. This was maybe 2 months ago. Since then its gotten louder each week. It sounds more like the pump this time. So I separated the motor and checked the impeller and no signs of issues. Only thing I've noticed is that one of the skimmers doesn't appear to have strong suction like the other skimmer so I think I have a block somewhere. Would a block cause the pump to be more noisy than normal?
