Tap water is icy cold and was until recently free in my neck of the woods, so an aspirator working right off the shower worked well. SWISM's was all-glass, rather different-looking than in the picture, and pulled MDP2P at around 166 C even with restricted water flow (to save water he'd ramp it up to full vacuum, then back off the water flow until it was just above the point that it wanted to suck water back into the system - oh, and don't flush the toilet while doing this!).
Going to have to look into this Yellow Jacket thing whenever SWISM gets off hiatus, sounds good...
