This is embarrassing to say the least. I finally decided to break the bank and get an auto siphon so I can quit filling the tubing and racking cane with water to create a suction. So I get this thing (Fermtech) and follow the instruction practicing of a gallon jug of water. CANNOT FIGURE IT OUT!!!!!!!!!! It says Start a siphon with a single stroke! I followed the directions of extending center tube halfway and submerging about 8" and giving one or two strokes. All I get is a lot of resistance, bubbling, and splashing everywhere. No siphon. I have a bottle filler attachment on the other end. What the hell am I doing wrong? This should be so simple but I spent an hour wrestling with it before giving up. At least I didn't harm my actual beer which I am bottling tomorrow. If I cannot get it I'll just have to re-attach my racking cane and do it the old fashioned but reliable way. HELP????
