Hello, running into sloshing/grinding/bubbling noise for first time on 3 year old pump. Cleaned out and lubed all connections, O-rings, impeller on suction intake end, including the pot and volute assemblies. No visible damage or water leaks. Only seal I didn’t check is mechanical shaft seal. Water temp is in 40s-50s. Could it be the cold? I also had scary bearing whining noise one really cold morning. But that has since stopped. Any advice on what to check next. Or what would be a good replacement pump for my Pentair CC150 Cartridge/Base? ThanksSloshing/Grinding Noise: https://youtu.be/-rrMrlOEmtI
