[QUOTE=Raspy;736575]I've only had one place ever check and turn me down on an expired tank. And it looked perfect. "Re-certification" is kind of a joke and common sense. If it is severely rusted, or dented, or has serious road rash, toss it. If the O ring in the Acme valve is cracked, replace the valve. If it looks pristine and is out of date, it's just a legal matter. Stamped with a new date, it is good to go for another five years. The magic stamp makes it totally safe again.
I went into a local propane
yard, where they were re-certifying hundreds of tanks, and asked them what re-certifying meant. Answer was: "we re-paint them and stamp them with a new date".
If mine become out-dated, I'll do the same by stamping them myself. I have had a couple of Acme valve O rings crack and that seems to mean the entire valve gets replaced. When this happens, they will leak even with the hose screwed on tight.[/QUO
In my area of California, our local U-Haul
does check the date stamp and was turned away. Down the road is a tool rental place that does not check or look over the tank and have never had a problem getting refilled.
