Worst i have had was a 750 bag full and the drain pump air locked on me. I couldnt get the line off and i couldnt reach the pump due to the bag. I had to keep fillign the bag to force water threw the drain pump then it finally started working. I used to get air lock all the time with my 400s. It sucked. I havnt had air lock or drain issues since i vented the bags.
