I have a CPR Bak-Pak skimmer which is about 5 years old, and lately it's been making buzzing noises. Otherwise it still functions fine. Does the whole powerhead need to be replaced, or do I just need to replace the impeller?
 
Take the power head apart and clean it out and closely inspect the impeller, usually the supports at each end of the power head oval out allowing the impeller to move laterally creating noise, if that's the case you need to get a new one.
 
As Keith said, take the pump apart and clean it. I would soak it in 100% vinegar for a few hrs. That will dissolve any calcium buildup that may be on/in the pump.
