Two years ago I started having troubles with my propane hot water heater. It would fire up, run for 5 minutes or so and the fire would go out. Sometimes restart, sometimes not. I posted the question here and got lots of advise, but due to other more important stuff never go to do anything about it. I finally ran the tank almost dry this past summer dealing with constant no fire issues. Filled with 12gal this last October. Had troubles relighting frig, and hot water heater, but when I finally got them lit, I have not had a single problem with them since. Frig works and hot water heater lites and heats without incident. Has anyone heard of getting a bad load of propane? It was just that one fill that gave me problems. So, if you wait long enough things self heal?
We hear often of GMC'rs getting a bad load of gas (I did once) and having to run it out.....but Propane?

Sounds like a regulator and low propane pressure problem when the tank was low.

Perhaps the blend was wrong. It’s supposed to be 90% propane with ethane, propylene and butane and odorants making up the rest says wikipedia. Regarding bad gas, BP made the news for a week a few years ago when the local refinery sent the wrong blend to Chicagoland stations. Cars had to be towed in to shops with typical $1000 repair bills and very busy lawyers. I think your bad batch theory makes sense.

Propane, like gasoline is seasonally blended. It contains more volatile
components in the winter to adjust for the cold weather. In the summer,
just the opposite. In normal temperature ranges, both blends should
overlap well enough. But in extreme heat like over 100° Farenheit, winter
blends may have the tendency to vent or outgas. In extreme cold, like below
32° Farenheit, summer blends may not vaporize as well. Still, another
issue is the water content present in your partly filled propane tank due
to condensation from heat/cool cycles. That can freeze in extreme cold
temperatures, and affect regulators.

Chances of getting BAD propane is slim and none. Your problem could have
been more from contaminants in your tank such as water and dirt.(These
tanks are 40+ years old and have probably never been apart.) It would have
been beneficial to have the tank cleaned and rinsed with alcohol and blown
out with air when it was empty and have the regulator replaced with another
2-stage regulator. You would not believe the poo that is inside these
tanks since they were installed. The fresh fill of propane may solve your
issues until the tank one again because low. Just my opinion, yours may
vary!
