what to do now

so i know there are a couple threads about this already but
i am now the proud owner of
4 out hydro 3000psi steel tanks born in 2007
2 pure energy carbon fiber 3000 psi tanks from 2006 and 2007
a crossfire carbon 3000 from 2003
a 3e carbon 3000 psi tank from 2003
And last but not least
2 dxs 4500 psi tanks born in 2006

all of the carbon ones look brand new
in your opinion are any of them worth re hydroing?
im also assuming the 15 year life applies to the carbon 3000s as well?

Yeah I was done with HPA as soon as I learned they had actual expiration date

I'm sorry I'm not very helpful, the world is such a wasteful place
Like my car, if I wanted to turn around and sell it I have to get it cleaned up, fix a couple of things, get it registered for my state, pay the past-due property taxes, get it inspected, and after all it would be break-even so a lot of work for nothing
Its a smooth-driving car, too

I collect computer stuff and when it takes up too much space no one wants the stuff -- I thought it was "good stuff" and to me it was
More waste
And I can imagine someone having a ton of out-of-date hpa tanks with no where for them to go except to the dump

So now I am seeing what the gurus mean when they say let go of physical possessions, it all goes back to Yahweh in the end

Did you sell your CO2-powered Sniper II?

The expiration date is for your safety. Metal fatigues over time, especially when it's exposed to pressure. Add in elements like hot fills (rapidly filling a tank up to 3k+ to where the friction makes the tank warm), and moisture and debris in a systems that aren't always up on their maintenance (can lead to some corrosion). Life spans now make sense.

Also, they're aluminum. Take the reg off and recycle it if it's not getting retested.

To the OP. I believe the life spans are all 15 years regardless. The difference would be if it was on a 3 or 5 year rehydro cycle. To find that out, you'd have to look up what the DOT/TC stamp is.

And since they are aluminum I could melt them down and make some sweet grips or something like that.

You could, but the aluminum they're made from is likely a different alloy than the 6061 series aluminum used for markers, ect. Also keep in mind that with the wrapped tanks, you'd have to deal with the wrap and epoxy prior to melting in a forge/foundry.

..4 out hydro 3000psi steel tanks born in 2007 , These are steel and can be re hydro'ed a bunch.
I have some at the shop that have been done 3 times so far.
Is it worth getting them done? Depends what your local hydro charges. 20 tanks cost the shop 10.00 each..
We do a tank exchange, give use you old tank and we give a fresh hydro one for 20.00 or tank and Reg swap for 35.00.

2 pure energy carbon fiber 3000 psi tanks from 2006 and 2007.

Most CF tanks from around 2007 are 3 year tanks and still sell pretty fast on ebay for 65.00 once hydro'ed. So depending on the hydro price..........
Same as above for for the DXS tanks.

Best bet is find a local fire extinguisher company and check prices for retests/hydro's

Every place I've gotten a quote from ($25 being the cheapest in the Denver metro area) has offered cheaper rates on bulk amounts, starting at 10 ea and getting a better rate at 10+ increments.

I'd source a SCUBA shop, and find out who they use for hydro static testing. They are usually pretty open to helping you out if you aren't trying to re-hydro SCUBA tanks.
