What is the best way to empty out propane

Last week I had our propane tank partially filled, as usual, we bubble check for leaks. The attendant found a tiny, tiny leak where the indicator screws into the tank. I got approximately 7# of LP gas in this tank.

now that I am home, I like to get it fix. what is the best way for me to empty out the propane tank? HELP... what do I do with the 7 # of LP gas?

a little bit on my background, I've been a refrigeration contractor for past thirty years, I repair many Freon leak, natural gas leak in home furnaces. So I am very familiar on how to properly repair a gas leak. However, I have never had to empty out an LP tank and then trying to fix a leak. suggestions are welcome.

If you are getting a propane alert I would take the rig to a propane dealer and have them pump it out. If not you may be able to open the doors and fire up the furnace and stove. Run until the propane is empty.

If it's a portable tank get it out in the open some where and open valve and let it out, if it's mounted on Rv hook a hose to it and carry hose out somewhere in the open and let it out . This is what gas co, do or put a torch on it and burn it off,

You can't open portable tanks anymore, with the new valves. You can open the bleeder, on the side of the valve and let them slowly drain, away from flame and basement windows..

But it's not a portable tank, they don't have indications.

To the OP, you have at least 7 gallons in the tank. Bulk propane is delivered by the gallon, not pounds.

If safe to use, I think the heat will be the fastest way to use up the gas.

Most propane suppliers, not the places that you normally buy propane(the ones that supply propane to home tanks), have the means to pump OUT the propane, so I would check with them first.

That tank has high pressure so anything applied will be blown off.

The indicator has a seal and should be servicable.

Propane dealers hsve pumps for transfering fuel and it is common.

So either cook everything in mh and consume it or call a dealer to seek repair.

It may be less hassle for you to pay the dealer to pump out tank replace seal and test then fill than for you to replace seal and hope.

Replacement also option if old tank.

Thank you all for your suggestions.

I think I will go North for a camping trip and let my furnace use it up then come home.

One more question; The gas station attendant mentioned I need to have my tank re-certify (something like every ten years, I don't remember). What does that involve? does it mean if I don't get the tank recertify, they will not fill my tank anymore?

I believe your tank is manufactured by Manchester Tank. I would check with them and see what they say. Back in 2002 I had a coach with a 40 gallon tank that I sanded and then painted. While I was admiring the beautiful paint job I did I saw a small bubble form at one of the welded seams. I contacted Manchester Tanks and they told me at that time the tanks were guaranteed for life. A truck arrived at the house a short time later, they crated the tank and took it back, fixed the weld, and sandblasted and paint the tank all over. It looked brand new when they were done with it.

Just a thought, and it couldn't hurt, right?

Taking the motorhome for a camping trip sounds like the best scenario. We had a leak in the tank of our 2001 motorhome. We contacted several dealers to potentially pump out the propane. Unfortunately they need a liquid port to pump everything out, or transfer it in a gas form to other tanks.

Since our tank didn't have a liquid port and it was nearly full it would have taken a number of tanks to hold the gas. We ended up having to take the motorhome to a remote empty field, hooking on several lengths of fill hose and let it slowly drain off.

I recently went all electric in my new motor home and removed the full 30 gallon tank. I had the same dilemma....what to do with the propane because the tank was soooo heavy. I called the local propane dealers and one said they could it out at their southern facility 90 miles away.....no good. I called another store and they said, I would just let it vent or buy one of those cheap grass burners or a turkey deep fryer burner and just let the propane burn off. Luckily, someone bought the tank with the propane still in it ($90.00 of propane).
