Then someone on this group mentioned the air vent on the sink itself,

It did not take long to clean the blockage in the over-flow/air-vent
and the sink has worked perfectly since cleaning it out.

I know periodically check to see if it is blocked by running water
into the sink until it is running through the overflow.

I remember that thread - it caused quite a bit of dialog here as many people
tried to figure it out. It was a good catch by (who-ever) brought up that
idea of checking the overflow. Seems to me it may have been Edwin, but I'm
not sure...
