i think its a temperature thing. never had this issue when running with dry ice.
How cold r u getten
i just dont know at what point in the process the moisture is coming through. i think its from the material or maybe condensation from the column. i do a 10 minute soak and maybe the solvent cools down too much. my chiller gets to -20 to -30.
What the humidity in ur lab? Where are you off gassing , any source of water near by

Go through every fitting follow every line and tighten em, u find a loose fitting there ur answer but that where I’d start
And I would pull a hard long continuously vac in the system if u can
thats where your moisture is coming from. its condensation from the unused coil. u should vac it and keep it vacd if ur not using it cuz the temp swings cause condensation.

What exactly makes you say you’re getting water in the pour?
What does it look like? Any pics?
Does the oil sizzle on the nail when you go to dab it?
I have never been a fan of long soaks like you mention. I don’t think they’re necessary.
