Default How long does a corny have to hold pressure to be "good"?

I'm fairly new to kegging, and have a question. I bought a couple corny's recently and they were *supposed* to be shipped under pressure, so you'd know they were good when they arrived. One had no pressure in it, the other made a tiny pfft when i pulled the relief valve. I called, and they immediately shipped me 2 more. The new kegs had the same problem. I called again, and they said to test them out, 'cause they can sometimes lose pressure during shipping (really??). So, I figure sure, no harm in trying. I took 2, pressurized them to about 10psi, checked for leaks with star san, no leaks. Left them pressurized for 5 days now, they still seem to be holding, based on pulling the relief valve briefly.

So, are they good? They seem good to me at this point, but I don't have a lot of experience.

A couple of my kegs don't hold pressure with no gas attached, but those poppets need to be replaced. If they are holding pressure after 5 days I wouldn't worry about it.

try changing all your orings (particularly the diptube ones) and try again. one time I wasted a ton of co2 because my tank just wasn't holding pressure.

turns out I forgot to put an oring in, I felt pretty stupid

Good to know, thanks.

Don't need to try again. It's still holding pressure. The question was how long does it need to hold pressure for me to call it good.

That would be a pretty furious pace to maintain.

After 5 days holding pressure I'd call them good. +1 on the keg lube; a little goes a long way.

If you want to be scientific about it, you could rig up a keg pressure tester with an extra keg disconnect, some copper fittings, and an extra CO2 gauge. Cost would be probably less than $15-20 depending on what you may already have on hand and how fancy you want to get. Overkill? Yeah, probably. But I'm a DIYer at heart...
