Can you blow threw your airline, see bubbles in the skimmer body?

Yes I can.
I had already stripped everything down and cleaned it all but maybe I missed something.
I am going to fill a bucket with hot water and vinegar and run it for a day or so.
The one thing I might have missed is where the smaller tube hooks back to the skimmer.
Might even swap out the air lines for new just because.
Then lets see what happens.
