I have a 30x15 saltwater fiberglass pool. Pool and pump are 6 years old. Our current pump is a Speck-X ES90-III. This pump is the loudest pump on Earth. We are convinced the pool installers either installed it wrong or messed it up upon installation. It’s a loud grinding sound that you can hear from several houses away. After 6 years we’ve had enough and we want to replace it but not sure how to go about finding a pump that is right for our pool and compatible with our filter…we have a Heyward sand filter. A quick Google search doesn’t give many results for Speck pumps…so I’m thinking of replacing it with a different brand? No clue. Any guidance or a starting point is appreciated
