tube bubbling fine
adjustment for air is at 12 o'clock
but getting NO output in drain off hose
good amount of brown stuff in cup , but just sitting there
when it was 1st set up - i had too much output - just clear water and lots of it coming out
now i can't get anything to come out -
not enough to flow out into the drain hose
very little foam at top of tube
what can i do ?
