    Confused Liquid refrigerant in hose to recovery tank after purging

    After purging my recovery machine and shutting off all valves, sometimes when I go to disconnect the hose to the tank there is still liquid refrigerant in it. I have a sight glass on the tank's liquid valve and can see it fill with the liquid refrigerant if I don't shut off the tank's liquid valve quick enough. Thoughts on why is this happening? Do recovery tanks have a check valve in the liquid valve?

    I don't know of any recovery machine that forces absolutely all the refrigerant from the discharge line into the recovery tank. The ones I've used leave the line still pressurized and depending on the conditions, I have also seen small quantities of liquid refrigerant while disconnecting.

    Recovery machines can only remove the liquid from their own condensers. There is no way for them to clear the hose of liquid. It happens on a regular basis for me. The only time I don't see it is if it's a hot day and I'm cooling the tank off with a garden hose. The tank will be at a lower temp than the hose so the refrigerant will want to be in the tank instead.

    You pick the recovery unit up over your head and let it drain into the tank. Works like a charm.

    Sometimes it is hard to tell if this is a spoof or not, until you get done reading the whole post and think about it for a second or 2.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?
