I dont take the tube out for cleaning... I simply wash down the inside of the keggle and use high pressure water and blast it in reverse through the ball valve to flush out the tube. Here is a link to my photobucket site, you have to see my system. I use a double 10 gallon cooler system with a SS false bottom. I have through the wall digital therms and a sparge arm. This is my dream system, I know, simple, but it really is.
