Most of what I see on here regarding testing vacuum pods, etc just says to go to the Y7 "tree" and test them individually and if they hold pressure they are good, if not they aren't. I have found a couple that don't hold any vacuum. Of the ones that held vacuum, some I could pump up to like 20hg or so and hold. Others that held vacuum I could only pump it up to like 5 hg. My question is, is 5 hg ok?
