That odd-looking setup from Rego - not Marshall - (which appears to be a changeover valve with first stage screwed onto a separate second stage) is apparently discontinued... although it is still listed in Australia.

This statement in the linked document:

Most of the 30-pound and smaller propane cylinders that I have seen for sale in recent years (from both Worthington and Manchester) have been vacuum purged at the factory, so no additional purging step is needed before first use. It is worth checking this if getting a new cylinder.
I have taken 3 new "Prepurged" 20 lb propane cylinders into be filled . Every propane dealer I visited in my area required the tanks to be purged or they would not fill the tanks.
The propane dealers had zero faith in the reliability of prepurging.

Plus they then get to charge you to purge - at least all the ones around here do! The new Worthington prepurged one I bought on sale at Menards was actually filled without another purge at the local UHaul.

That's an assumption on your part .Two of the three propane dealers purged the tanks for no
charge. I too bought my tanks from Menards.

The propane dealers must be nicer in your neck of the woods!

Interesting. I have no faith in most of the places which sell propane, because they are clearly not competent:
  • almost none check the condition of the cylinder or the certification date (Costco is the only exception I've seen)
  • small cylinders are filled by weight here, and none (except possibly Costco) ever check the tare weight
  • one young guy and the female "trainee" at a major truck/RV stop chain were so busy flirting with each other that they walked away from my motorhome leaving the bleed valve wide open to endlessly discharge propane vapour
  • the propane dealer which sold me a used and recertified (by them) large cylinder did change the valves (at least they looked new), but didn't stamp a new certification date on the collar
  • the same propane dealer that sold me the cylinder without the stamp has since repeatedly filled this cylinder, never noticing that it does not have a valid date
  • one idiot even filled a 30-pound cylinder with no scale and not using the bleed valve, counting on the Overfill Prevention Device to stop the fill
I suppose I could go to a propane specialist - rather than a gas station - for the first fill, but the place that didn't stamp my cylinder is one of these. Given the places most of us buy propane and my experience with them I would rather trust the factory that make the cylinder than the kid who may have taken the propane course.

Realistically, once the cylinder is vacuum-purged at the factory, even leaving the tank valve wide open won't introduce more than 6 grams of air and less than a gram of water into the cylinder (unless you pump air or water into it, or put it underwater). The concern explained in the article is that a cylinder which has ever been purged may be pressurized with contaminated air, but the cylinder which has been vacuum-purged can't pressurize itself.

I have concluded that as the user, it is my responsibility to monitor the tank condition, track the certification date, and check that it is not overfilled.

This happened to me twice! Once when it was 10 degrees F outside. I didn't read through all the posts so maybe someone already suggested the following. When this happens again go outside and shake the tank for a bit. Everything will work again through the night. That's it, it works, trust me.

FullTiming-propane not happy with cold weather

I agree with Brian - I have little faith in most places that sell propane. That's why I get it at a propane shop and not some place that just happens to sell propane along with everything else.

And the upside is that not only do they know what they're doing, they usually sell propane much cheaper than other places.

We filled our tanks at a propane shop in Gonzales on our way to the Matagorda Rally. The left took 2 gallons and the right took 1 1/2. The charge was 8 bucks.

How do they fit gallons into a 20-pound cylinder?
