Alright, I made two changes (yes, poor independent variable isolation, I know!) and it seems to have worked out. As I mentioned, I heated the hose segment to connecting it to the wand, which allowed me to get it a little bit higher on the wand shaft. The other change is that I positioned the clamp just below the bead in the stem. Hmmm come to think of it, there were actually 4 independent variables, as I actually changed the hose connecting to the adapter and tightened the clamp a bit more. Clearly, I’m no scientist.
