Is yours mounted below the waterline?.
Yes it is. In fact, when I do it, I have to control the flow with the intake valve. A while back the same thing happened and someone suggested taking the top off and it worked. Not sure why, but I think it reduces the surface tension in the rest of the line. Doesn't really make sense to me because I would think the water pressure from the intake would offset any surface tension. Anyway, it didn't work this time!
