for those of you with a center sac without a vent, how do you deal with the air buildup in the sac? My center sac (10X16X70) does not have a vent port (only fill and drain). I've tried turning off the fill pump then disconnect the fill port hose to burp it, but the port is on the end of the bag, so it's just water that comes out. Any ideas? It's worked well to roll up the bag sqeezing the air out, then fill it, but it's a pain to do that each time.
