We have a Rheem pool heater and a small in ground pool. Normally, if the pump is running too slow (but not slow enough to shut off the heater) it will start making a whistling sound. I've always assumed this was kettling and if I run the pump at a higher RPM it goes away. So, I run the pump at 3000 and that's worked fine for months.
Recently, it started making the whistling sound at the higher speed (3000 RPM). If I turn the pump speed up to the max, I can still hear it, but it's slightly better.

- Filter is clean
- There's a SWG after the pump, seems to be working fine
- Water temp is around 90-94
