Guy:

I was really talking about plastic carboys because those were
mentioned in the original posting about vacuum but granted, lot of
this depends on the setup, especially what kind of vacuum pump one
uses. I'm curious about your setup, especially that part about locking
the vacuum - how do you do that?
