As many have said, you need to add a stainless steel nut or washer(s) to the intake tube to get it to stay submerged. Otherwise at some point, you will start getting only air out of the tap, despite the keg still being partly full.And even still - with a heavy stainless steel nut on the intake tube - it still occasionally gets tangled, requiring me to open up the keg and reach down in to untangle it. I’ve had some beers become unpleasantly oxidized from doing this.I’ve also tried using the FLOTit dip tubes and have never had this problem with them. The Clear Beer Draught System also avoids this problem of the intake floating above the surface. When my current keg is done, I will be discarding this dip tube and replacing it with another FLOTit. It costs a little more, but not as much as dumping out several gallons of oxidized beer (sniff).

I purchased several second hand kegs and some were missing liquid out tubes. Saw this, read a lot of info on these and knew this would be the perfect solution. AND, it is. Decided I could make them cheaper, so, I found a schematic to do so. However, after I purchased all the parts, they were just a little more expensive, not counting my labor and wait time to get some of the parts from China. Also, this comes complete with a dip tube. Short dip tubes for the liquid out side on a Cornelius keg are near impossible to find. On can use gas in tubes but they are short and hard to attach the silicone tubing. While I have made a few of these, in the future I will buy these as they are relatively inexpensive and work quit well.

Using for corney kegs, so a few inches of silicon had to be trimmed, and I added a 7/16 nut to each of these just to make sure the tube stays below the liquid. Works great!I have three and will get more. I can ferment and serve from the same keg. Absolutely game changing. After an over night cold crash, I'm drawing fairly clear beer. After a few days, is even better.

So, the metal tip of the beverage intake is not really weighted enough to keep it submerged. I have three of these things, and occasionally it will rise above the surface and you get a blast of foam and gas. Sometimes jiggling the keg gets it to submerge, but not always. Having been forced to open the keg and exposing my beer to air, reaching in with a sterile glove and repositioning the damned thing (which does not even always work) has made me re-think using this device. Oh, and you can count on losing the last quart of beer at the bottom because there is no guarantee that the tip will sit at the lowest point. I suspect you can pay more for a better product. I guess you get what you pay for.

I love the idea for this, but it will sometimes "spit" and pull foam off the top if your beer/beverage is highly carbonated. It should be weighted down or sit a little further down. I think others have found a way to attach a stainless steel washer or something to the drain tube to keep it sitting a little lower. I also tried using this in a larger torpedo fermenter and it did the same thing and sucked a lot of debris off the top.
