You can observe what's going on with the trade-in cylinders if you know the math.

First, look at the collar of the metal cylinder. YOu're going to see something like WC 47.6. If you know to do the math -- namely, multiplying as (WC X 0.47), then you'll find that you've got yourself a ~20 pound cylinder. In other words, that cylinder CAN contain ~20 pounds of propane.

Now look at the removable plastic wrapping on the trade-in bottle. And check what they call "net weight" (meaning the weight of the product without the packaging). If it is less than ~20 pounds, well, they underfilled the cylinder. Indeed, I think that you'll find that the net weight on the plastic wrapping is usually 15 pounds.

ANd that's how you'd know that the trade-in outfits are not filling their propane cylinders to capacity.

recertify is easy. That doesn't mean you get another 12 years. The propane dealer will stamp a new date on the tank. The tank I had done for my home BBQ got 5 years.

Take them to A & B Propane on Military Highway in Chesapeake. They just certified and installed a Gauge on each on my 30lb tanks. They will also give you a honest evaluation of your tanks.

Propane Tank Recertification

I agree with BOBSTOCK's comment. I've had my ALUMINUM 30 lb propane tanks since I got the 1994 30 ft. Excella Front Kitchen back in 1996. I prefer their lighter weight and higher capacities vs. steel tanks. I got mine recertified here in Phoenix for $20 each after calling around the propane dealers a bit to find one who would to it... That would be my solution if possible...

Angry Horizontal Tanks

Sadly, when the rules were written in Canada for OPD valves they did not take into account horizontal tanks like they did in the USA where they grandfathered the old non OPDs. Thus my, lovely, USA recertified 40 lb aluminum tanks cannot be filled in Canada but can be in the USA.

Well here in NJ it cost $30 to recertify a tank for 5 years that would be $60 with the second time to make 10 years. This is well worth it for aluminum tanks. Not worth it for steel tanks you can buy new for $65 that are good for 12 years.
Now the reality is the barbecue tanks have a 25 lb capacity, since they can only be filled to 80% of capacity they can only be filled to 20 lbs so they are called 20 lb tanks. Also most exchange places only fill them to 15 lbs, Still a cheap easy way to get a 20 lb tank "recertified".

For what it's worth, the 30 gallon aluminum tanks that came with our 2000 Excella were manufactured in 1974. Did not ask the previous owner why the originals were swapped out, but there was no issue getting them tested/certified at a propane supplier in Texas. The same shop installed a new valve assembly last year that cost around $25., and we have had them filled in nearly every state west of the Rockies without question.

The owner of the propane place who certified them said he would love to get his hands on some aluminum tanks because they last forever, but they are hard to find. If you do buy replacement tanks, worth considering going aluminum if you can.

Visual recertification

Recertification is pretty easy, I took mine to A&B Propane in Chesapeake VA a few years ago and have traveled east to west coast with no problem having them refilled. If memory serves me correctly, there was not a charge, but I did have them filled while I was there since we were getting ready to hit the road.

1) Is it better to just buy new tanks or get them requalified?
2) If requalified, anyone know where in Newport News, Virginia?
3) If buy replacements, anyone know where in Newport News, Virginia?
3) I don't see many mentions of 25.4 LB propane tanks online, I wonder if 30 LB tanks would fit in my existing case? There's no more width available in the silver sleeve, but could go a 3-4 inches taller.

Many thanks!

Tim
Tim,
Over the years, I've had several tanks recertified at commercial propane dealers that service/refill farm, industrial and residential tanks. If you get your tanks refilled, they usually charge only a small additional fee to recertify and label the tank. The recertification process involves an inspection of the tank for good mechanical condition and a leak test of the valve/valve stem, etc.

One of the suppliers that I've used for this service with excellent results here in Wichita, KS is Ferrellgas. Ferrellgas also has a franchise there in Newport News, and here's a link! I'd give those folks a call!

All my best,

Steve

Not really...Vintage Trailer Supply carries them if you're in the market.

Actually not true. I have a letter from Transport Canada that says US certification is valid for refills in Canada and here is the link:

https://tc.canada.ca/en/dangerous-go...-0#requalified

Michigan recertification at an approved facility was $5 plus a fill of propane.

We bought 2 30lb tanks at Camping World about 2 years ago. I believe that Worthington Tanks are the best, their paint is better too. Possibly they are US made as well. C/W had a sale and we are members so we got a good price. Our A/S is a 2007, 27fb with original size tanks that came with it.

Hi, I see where USA and Canada recognize the tanks and their markings, but I still didn't see where Canada recognizes USA re-certifications. I was told that by two propane dealers. [ this was about two years ago]

Seems that I've been told you only fill to 80% capacity.

Yep, and if you follow the math in my post, that IS 80%.

Here is from the email from Transport Canada's Dangerous Goods Transportation division:

As discussed, the FAQ to our website. https://www.tc.gc.ca/eng/tdg/moc-cyl...ml#requalified



This describes that DOT cylinders can be used in Canada, and that a requalification facility approved in the USA by PHMSA must requalify and mark DOT cylinders in accordance with the U.S. Department of Transportation's Hazardous Materials Regulations entitled Title 49 of the U.S. Code of Federal Regulations (49 CFR). Their RIN or VIN (requalification identification number) will be marked on the cylinder.



A requalifier can be looked up by their RIN/VIN on PHMSA’s database, and their approval letter will indicate if they are allowed to mark the cylinder with an adhesive label. Not all companies in the USA have obtained this approval.



Since this label is permitted under 49CFR, if the cylinder was requalified in the USA in accordance with 49CFR, the requalification is recognized in Canada. Note that Canadian requalifiers are not allowed to mark with a label on metal cylinders.



Feel free to contact me if you have more questions.

Absolutely. See my previous post. The companies selling tanks have been forced to actually sell them according to the 80% capacity they can be filled to. Therefore a tank with 25 lb capacity that can only be filled to 80% is sold as a 20 lb tank since that is what it can be filled to.
