Default Losing faith in Better-Bottle carboy closures

I am using a BB 6 gal with the NPT to 1/4 hose barb, the hose going to a class of water for an airlock. I checked on it this morning and found the water level in the hose to be at the same level as the water in the glass. If I lift the hose slowly and keep thy end still in the water, the water level in the hose stays even with the glass. When I put the hose back in the water, same result. This tells me that the pressure inside the carboy is equal to the outside.

The stopper/adapter/barb elbow were assembled wet with starsan. When I racked this to secondary, it was showing activity and pushing bubbles. Now if I give it a gentle rock, it pushes air down the hose, but then it equalized again.

Anyone seen this?

I really have no idea of what you have there.

I use a #10 stopper with an airlock or the Better Bottle blow off setup sold by Northern Brewer. I have had no problems.

Maybe the stopper got pushed out a little bit.

The big stopper is pushed in, the small adapter is fully pushed in, the NPT part is tight, the hose is on past the second barb.

I suspect the inner o-ring is to blame.
