How would you push D10? Must be a real bear to push room temp D50 then.
Can't say anything about d50, as we don't use it in our service. As far as pushing d10, in my limited experience with it, I've only seen it pushed by squeezing the bag by hand through the line set. I wasn't on the run, so I don't know what the situation was, but I do know it was a cold day, and room temp in the back of the truck may not have been optimal room temp.
