Which propane tank are these? Need to replace.

Just found out myself that the tanks are 10 year Certification since Jan 2017. That made both of mine outdated. The problem I ran into in Delaware is finding someone to do this. After checking with 4 LP companies it appears LP dealers in Delaware no longer do certification. So I purchased 2 new tanks on ebay for $112. I like the 20 lb tank idea though camping in cool weather doesn't work for me.

FYI run off one tank at a time we were told to open up both and we when through the gas in a month, one at a time we take about two and a half or three months. We live in it full time

Take the tanks to the local propane gas dealer and have them do a pressure test and recertify, and replace the hoses, the regulator can also be checked by the propane dealer and you are good to go for another 10 years.

My local Coscto sells new 30lb tanks for $40. If you're a member or have a friend who is you could also go that route.

Oh, didn't think about that. I do have a membership there. Will check that out the next time I'm there. Thank you kindly!

That is why I changed to the 20 lb. ones. When they close to date I swap them out at homedepot or where ever and never worry about having to buy new ones. I keep a extra full one locked in the bed of the truck for when one runs out and then get the empty filled or exchange it.

I also went to 20's on my travel trailer years back. 20's were much cheaper and easy to swap. I got a shorter threaded rod, and life was near perfect. My gas usage wasn't that high that I needed 30's.

you bring up a good point. The only difference is that you need to refill/swap just a little more often. We only fill our motorhome up once a year. It's a 40. Haven't filled it up this year yet and think it's around 2/3rds full. We don't normally use the heater either. We will normally use an electric heater, put the hot water heater on electric and the fridge is on electric unless we are traveling. We don't do a lot of dry camping.

It's actually 12 years for a tank cert as far as I know...

DOT Certification Requirement for portable propane cylinders WAS 12 yrs after date of mfg as stamped on collar

That requirement was modified as of Jan 23, 2017
12 yr certification was changed to 10 yrs

5 yr 'Visual Inspection' still 5 yr
7 yr 'Proof Pressure Testing' increased to 10 yr
12 yr 'Volumetric Expansion Testing' lowered to 10 yrs

Info is slow to update....SOME Bulk Vendors have new regs.
Some mom/pop outfits still using 12yr

Thanks OB. I didn't know that so good to know!

Guess I'll be visiting the exchange stations a bit sooner!

Thanks, I knew about the spewing liquid instead of vapor if the relief opened. I was curious why "12th Man Fan" thought they would vent by laying down.

Did you have them laying down while you were Hauling them. if so that would also make them vent when they are full.

What would cause a tank to vent when it is laying on it's side?

Just laying them on their side would NOT cause relief valve to operate.
Problem is IF relief valve SHOULD open due to high pressure condition (heat) or failure then LIQUID propane (vs vapor) would be spewing out of relief valve.

Vapor dissipates quickly
Liquid Propane will 'burn' flesh (extreme cold burn)
Very damaging.

That is why Vertical portable propane CYLINDERS should be used/stored/transported in Vertical position

Horizontal Propane Cylinders have different design...can be used/stored/transported horizontally


Propane TANKS......well those are permanently mounted in MHs or set on legs/pads as in residential/commercial use
Tanks....ASME

2 different vessels with different designs/requirements
