? about LP tanks
So, how long do you recon an LP tank, such as the size you use for a gas grill, can sit around unused? Any reason why it wouldn't last for years? Talk to me guys.

my understanding is that it will last many years. Propane does not degrade.

But the tanks themselves rust. Pinhole leak = kaboom!

Be sure to store them in an outbuilding away from the house. I had mine in the garage for a long time because it's temperature controlled, but someone here put the fear of God in me describing what would happen if the house caught fire. BOOM! The place I have them now is out of the weather, in a shady place that doesn't get too hot, and up off the ground to protect from moisture.

I found one that got covered up in the corner of one of my barns for 6 years.
Hooked it up to the grill and used what was left in the tank. It still had the old style valve
Propane stores forever and the tanks last that long if you don't let them rust

If it is outdated, even if it is in excellent shape, they may refuse to refill it for you.

Yep. I've been at a fire where a propane tank blew. Big boom!

Yes, it's illegal to refill them, and a valve replacement often costs more than a whole new tank if you shop around

Mythbusters tested this recently and showed that the safety valve should release the propane vs. the tank exploding:

The build team tested the myth that a propane tank being stored in a garage became a rocket and soared 150 feet in the air when the garage caught fire. So, will a propane tank turn into a rocket in a fire? I had my doubts about this one. And, as it turns out, under normal circumstances, no it won’t.
Propane tanks have pressure release valves. After building a shed, filling it with wood, charcoal and gasoline, adding a propane tank and setting the whole thing on fire, the pressure release valve did exactly what it was supposed to do and let the pressure out gradually. No explosion, no rocket.

Of course, in typical Mythbuster style, they disabled the safety valve and amped up the experiment. Under those conditions, yes, the propane tank will blow.

I've got some old ones, over ten years, and they still have gas in them... I'll have to trade em out for refurb ones next time they get filled... $18 bucks, and they're refilled... afterwards, it'd be just a regular refill. I keep some in the barn, some are out in the open (newer ones with good paint jobs).

had a fire years ago , the large household 500# and 1000# tanks have a blow out valve when it blows it is lik a rocket taking off in the rong direction till the tank is empty flames 60 feet in the air
but the small ones boom fire ball , an nold supervisor of mine had a fire with his travel trailer when the 2 20# tanks he had just filled went wow what a fire ball and i only saw the picture they took while standing in the feild watching the rig burn they had already used the little fire extingisher , they had just gotten tires and the garage put his spare up under the truck wrong , it was touching the exaust , the spare tire caught fire and they couldn't get it out
