LP tank Re qualifying?

Sorry for the confusion. I'm talking about OPD valved tanks. Do you still think after the first visual re-qualification I should just get new tank?


I'm still very interested about the qualification requirements for after the 17year re-qualification. Would it have to be Hydro tested at 22 years or would the tank be to old according to federal Law to be re-serviced? I'm interested in the theory if cost wasn't the factor. Thanks

Hi Rod and welcome to the forums. Federal law now requires OPD valves on all propane tanks. Propane dealers are not legally allowed to refill tanks w/o OPD valves,
If you have aluminum tanks, the cost of new valves might be justified, but if they are steel tanks your best option might just be to junk them.
I've seen new 30 pound steel tanks at Sams for just $39.

I believe after the 17 year mark, you need to have the 5 year hydro done again. This then becomes a 5 year re-cert until you decide to replace it or it fails.

Here are a couple of ideas as to what you might do with your tanks.

Here in rural Texas, we can still have the tanks with the old valves refilled so long as it is to be used for Agricultural Purposes Only. The dealers can't fill them for use on a barbeque grill or travel trailer, but if you are using them to fire a branding iron or to fuel a prickley pear burner, or for some other agricultural use, they will fill them for you. It is a $10,000 fine to the dealer to knowingly fill them without OPD valves for use in non-agricultural purposes.

Another use for old LP tanks is to modify them for use as portable air tanks for containing compressed air to use in inflating flat tires or blowing out water systems when winterizing your trailer. Conversion kits are available at most hardware stores.

On review

Now that better informed members than myself have offered suggestions, I apologize for perhaps being too hasty in my reply, which was based solely on my own experience.

Trade in

If they are the common steel tanks, and are only 20# tanks. Take them, as you use them up, to your local hardware (or grocery, or ... ) where ever you have a trade-in dealer. They should be easy to spot, they'll have a steel cage full of 20# propane tanks. The value is reasonable, just a few dollors more then a refill, but you get to recycle your old tank, get a new tank full of propane for minimal cost to you. Then next time you can refill as normal as they are only distributing OPD tanks now.

Here in Richmond, VA almost everyone is a trade-in dealer, except maybe the restaurants! But the grocery store, gas stations, hardware stores, you name it. I traded in some old tanks that I inherited from old grills, etc. but I was lucky enough to get an AS with aluminum tanks. We just had them serviced at a local propane dealer. Surprisingly, it cost us $40.00 to re-certify, re-valve, and re-fill each tank.

Seems to be two issues here. One is the OPD and the other is the periodic recertification.

OPD's are now required in most states for any refills for tanks of 40lb capacity or less. For those of us with aluminum tanks, upgrading the tanks is cost effective as new OPD valves run around $20 or so. But do be careful to get an OPD with the proper dip tube length (this is usually stamped on the colar). Many LP dealers aren't very careful about this. (WBCCI had a resource for Al tank OPD's a while back).

Recertification is usually just a simple visual inspection and a date stamping thing. New tanks can go about double the recert interval to the first but then all tanks need a recert every five years or so.

Note that these requirements are for the portable, vertical propane tanks found on most trailers. The DOT tanks on motorhomes are a different story.
[whoops - that's ASME tanks on motorhomes, DOT tanks on trailers. good article in August Highways mag p 58, too, on propane)

I had my original, 1967, 30 pound steel tanks refitted with the OPD valves by a certified propane dealer. He warned me up front about the costs involved in refitting versus buying new tanks. Since he knew how old they were, I knew he would not refit & fill the tanks if they were too far gone.

My tanks looked good to me although they obviously needed paint. New tanks are either white, or off-white, and would need to be painted. Since I wanted my tanks to be an aluminum/silver color in the final run, re -painting my final choice was a moot point.

I came out cheaper refitting my tanks with the new style valve although my visual re-certification is only good for five years instead of the 12 years associated with new tanks. They don't do hydrostatic recertification around here. Else, I would have had it done.

In five years, I will have the tanks re-inspected if the refill attendant feels it is necessary.

You don't need to apologize. You gave the most cost effective solution and that is what most people would wont to now. But I like to now to hole story. Thanks everyone!

Rod and everyone else,

Here in Taxachusetts, its hard to find someone that will recertify an LP tank. I brought 2 of them to a local re-filler and supplier of welding supplies, etc. He charged $20 each for a quick look-over and new date stamps. I thought it was a rip off for what he did.

I just stumbled on this thread. I'm bringing my 1987 29' Argosy out of storage after 10 years and trying to discover what might have to be done.

What is "OPD"? Does this affect the large tanks on my Argosy? Which I assume are original 1987 tanks.
Mark

If you have the horizontal mounted tanks, I do not think they require the OPD. They already have some sort of safety valve on them. I will try to find the information and post it here.
