Tanks stored empty for several years, what are the chances they'll pass hydro?

[UTscuba]

why not negotiate a price contingent upon passing hydro?

the price is contingent on passing hydro, but hydro for two tanks is $130, not sure what happens to the hydro fee if they fail

I am unclear what negative effect leaving them empty for an extended period would have, please explain your concerns.

I don't know what the issues would be, hence the post, but I have had the 'store with a min of 500psi' drummed into me since day 1 of open water

With Al tanks it is more important to check to see if they are the "bad" alloy, as they are more expensive to maintain, and some shops won't will them regarregardless. Is my cylinder made from the "bad" alloy aka AL6351?
In my area, there are a supprizing number of these on Craigslist some are VE and some are not. Some of the sellers are clawless about they are selling, others are trying to pull a fast one.

thank you that's REALLY helpful!

I just had a set of USN steel tanks with an initial hydro dates of 1941 and 1942 (and, according to the original owner, have sat empty since approximately 1959 when last stamped)

wow!!!!!

They will be fine. Take them here for re-qual as they are they only testers around SLC: Cylinder Services High Pressure Testing – Rocky Mountain Air Solutions

oh thanks, I usually do it through my LDS, but I guess they just pass them on there

I'd start shopping, around here hydro is about $30 and vis is $15.
