For those of you who have problems obtaining a good seal between the 2 liter bottle and the line out, why not try using a rubber stopper. I believe they are #1 or #3 and can be purchased at a chemical supply house for under $1. They can be had with one or two holes into which one can insert stiff plastic tubing. They work very well. -- Dave Whittaker ac554 at FreeNet_Carleton.ca
