A10 Whining noise?

[Nightynite]

Nightynite, thanks for posting about your experiences.  Last night I followed your suggestion to blow hard into the hose with the tank and filter removed, and my A10 ran much quieter.  There is still a slight bit of noise, but it's much better.  Going forward, I'll try to remember to do this periodically.

Thanks for the conformation, I was hoping this would help others.  For the second night, mines still running quite.  Knock on wood.
