Question Sanicon high pitch squeel

[Neal]

Have the Turbo 400S and has been working well. My sanicon normally makes a low pitch quiet sound when doing its job. Now it's making a higher pitch squeel. Not sure if you're supposed to do any maintenance such as lube on these things but anyone else heard this? Any suggestions? Sounds like bearings not lubed or something.

No experience with it not sounding normal. Thinking pump is the source of sound?. Maybe running water thru the pump a couple of times it will quiet down, good luck.
