Hey DC -
Were the other 55 gallon drums (closed tops with a square hole used?) I talked to RMC the other day and he said you had picked up that new 55 gal barrel. I am looking for a few but do not want to spend the 70 ea from the local provider.. A place downtown has used for 20$ each food grade, but I do not know that I want the hassle either. Did you have any luck with used?
Your system looks great btw!
