OK, I'll give this one the old schoolgirl tryOK. I've been struggling with this concept for days now. Help.
How is what is described here different than opening the tank and adding juice? The vacuum will be released either way, no?
BTW, I have been enjoying the sucking and fluttering method. That works.

By unscrewing the tank a turn or so, ( remember, the o-rings still keep the seal) the volume on the inside of the tank is increased. This increase in volume results in a lower pressure inside of the tank causing the air to flow through the coil to equalize this pressure difference. Then by reversing the procedure and screwing the tank back together, the volume inside the tank is decreased which in turn increases the pressure inside the tank, causing the juice to be forced into the coil to equalize the pressure.

Thank you for bringing it to our attention and providing the link.
