Any advice on draining lp tanks? The tanks have different ends on them other than what I have on hand.

We burn them off by attaching a weed burner....then take out a valve and fill it with water and some bleach....

Just seen the date the one tank was made, 1951...damn!
Now they are both drained, but I'm sure it not was the safest way, or legal. I just cracked the cylinders. I figured it was semi windy day so there wouldn't be a build up of gas. But the one tank frosted up on the bottom. Not sure what that is.

The frost is from the liquid gas vapourizing quickly and becomes very cold, I drained my current tank the same way, we were doing a job at a pirvate college and the kids were on hoilday, so I just placed it down the far end of the sports field and let her rip!, semi rural area, I think the roos were the only ones that knew I did it!................ :D :D

DO NOT DO THAT!!!!
I don't wanna be an arse here, but that is very dangerous!
I just turned 3 shades of white just reading this thread!
I will take pics of the set up we use and post them here.
LP gas or Propane, boils off from a liquid to a vapor at 270 times it's own volume. so gallons x 270= how much Vapor is really there.
the safest gas leak is one that is on fire or so we like to say... this does not mean to light the leak on fire, just means to not blow or vent gas because you cant see the cloud.
don't light the gas leak on fire tho lol...
Propane is heavier than air and will sit in the low lying areas and ditches. when it is mixed with air to the correct mixture the entire mass becomes very very flammable. raw propane not mixed with air will ignite around the edges of the cloud, but mixed with air, like when the wind is blowing for instance, the entire cloud is very very flammable.
I will do a video on this

On another note, the frost that Johnney seen is the result of the Vaporized propane leaving the tank faster than it could Boil off. so you have a very dangerous situation there as well because when the sound of the vapor copming out stops, we would assume it is empty... RIGHT?
WRONG! the level of the frost is the level of the liquid that is still in the tank!!! I could "go all BTU on ya" as the guy's say but I will spare you that hahaha.

no problem bro! I am glad nothing happened!
I am sure people do that all the time and have no idea of the risks involved.

Yes but it has less than 2% fat which makes it a bit tricky to cook.

Now that would be pretty cool.

Then I could see for myself if the water in the toilets really does spin the other way.

Ok, so I took franks words under advisement and bought a weed burner to use instead if just opening the tanks and letting them go. So I hooked it up and nothing came out. So untried the other tank and got the same thing. Thinking it was the unit itself I hooked it up to the tank on the wife's grill. That sucker came to life and sounded like a jet!
So I'm thinking thy may since they iced up during the time when I had them opened combined with the sub zero sub double digit temps that maybe it's still froze up inside? I moved them into my garage and will try it out in a couple days and see if there is any difference.

But anyone have input? Frank?

Thanks Frank!..... :D , some of you are going to be disapointed :-s , the truth is they do, mostly thats is!, but our toiltes are different to yours, ours work by water pushing the waste out where yours use a syphon method, really the best way to show that our water goes down clockwise is to use a sink or basin, so please sit back are relax and enjoy this small presentaion. questions will be asked after the show to see who slept through it!!..................DC!, I expect you to be full bottle on this subject! :p

:BDHorse: .... :wtf: ....our water goes down clock wise ........jets are probably angled the wrong way......and I have seen the two different flush styles......Once and I have a witness....we have seen a shower drain turn counter clockwise before....and when it happened I look up at my buddy and I said "Holy crap Mate, its a wibbly figgler"..... =))


If you can't fix it by sheer force or cursing......then it can't be fixed.....
