My local propane refillers have a minimum 20lb fill charge. I won't pay for 20lbs to recieve 5 lbs. Has anyone refilled thier 5lb tank from a 20lb tank? If so, what fittings do you need, and how do you do it? Thanks.

I bought an adapter from Cabelas and it works great. I think I paid around $22 for the adapter and it has already paid for itself. Most sportshops charge $3 or more for a single tank. My cost is around $ .75-$1 each. It's very simple, just follow the directions. It takes around 1min 30 seconds for each tank.

Yes 1 lbs works great. 5 lbs I never have have filled. Propane Products.com , the name is MacCoupler E-Z disposable bottle filler. Code word, MacCoupler. 16.95 + 7.00 shipping = 23.95 and love it. No need for the extention on the 1 lb bottles. This is the best 20 bucks I ever spent.

I have never filled a 5 pound tank, but I do keep all my old 1 pounders and refill. I bought my fitting from Jays it works pretty good you will only get them half to 3/4 full. I just use them for my latern anymore. I use 20 ponder for the heater for hunting or fishing.
To get the one pounders full, you'll need to have the 20 lb tank at room temperature, and the one lb tanks frozen. Flip the 20lb tank upside down before refilling.

Yes, I fill my out of date 5 lber all the time. First you need a 1lber adapter for filling the 1lbers and then 2nd you need a hose extension for hooking up a Mr. buddy heater or small grill to a full size tank. Hook them together And do what they said about filling the small tanks. 1 warm and 1 cold.

Thanks for all the replies. I fill my own 1lb tanks, but they have been freezing up when I use them. The pilot gets real low on my Mr Buddy, and then it goes out.

my 1lb gets frozen too on my buddy then it goes out. Leaves about a third in the tank left. I have thought about the refill deal but I heard they leak at the valve.
Are you talking about filling yuor 1 lb tanks and then seeing those tanks freeze up? Or, are you experiencing the freezing on new first time use tanks?

first time use. They freeze while I am using them. They stop working after using about 2/3 of the tank.
I know that as the contents of the tank get used up the internal temp drops to the point that frost forms on the outside of the tank. Not sure of the exact physics involved.

But, as the frost forms the internal pressure drops. If the tank is allowed to warm back up to, let's say room temperatures, then the internal pressure returns and the tank can be used until it is completely empty. Does not do much good out in an ice shanty where it might not be possible to warm the tank up in time.

Yes, the refills might leak at the valve but that is usually fixable.

The one pound tanks can get so cold they loose pressure and won't run the heater. They make some neopreon beer coozys ( I think thats what there called) or for paint ball guns that would help alot, they should be about the right size to slip over the one pounders
I have been think of trying to find something to insulate the tank while it is in use. One of these "coozys" might be the trick. Have you tried one of these?

I tried fill them 1 lb tanks up and can only get them to fill 1/2 way...the frezzing u are exspenicening is caused from the new tanks sitting out in the cold before use...warm them up inside before you go nexted time and that problem should go away...What i did is get a 5 lb tank it cost 5 bucks to fill and last a long time,It payed for it's the first 3 times i filled it this year...way more cost effective plus u dont need 3 tanks to go out with you...mark

I used to have this problem too. The one-pounder would freeze up and I would lose my heat. I gave up and started running the 5# tank with the hose adapter. Takes the hassle out of it all. I have even taken a 20# out on the ice when the 5# was empty and I didn't have time to refill it.

I never tried, but I don't think insulating the 1# tank would help. I was having that problem even though my tanks were room temp when I headed out. I don't think insulating would help because the tanks freeze from the inside out, so you would be trapping the cold in.

I dunno if a 5lb tank is a cheaper way to go.
http://www.amazon.com/Manchester-Tank-Equip-10054-3-Propane/dp/B000243QA0$50 just for the tank. Plus I think it would be more of a PITA to drag around on the ice. The 1lb tanks fit so nicely in the buddy heater.
There 50 yes butt price out the 1lb tanks @ 3 to 5 bucks depending on where u get them take 3 with you u have say at tops 15 dollars x say 4 fishing trips =60 bucks 3 1lb tanks are say 5 to 6 lbs 5 lb tanks are 12 lbs full i fill it up every 4 th trip @4.90 ive ive fished 12 times this year and have payed for the tank after the 4th trip and its cost mein lp gas15 for the season...you dont know your pulling a very little extra weight at all.....Goood luck mark
