Yes it is possible to fill one if you have the pol fitting and hose. Without a pump it will probably fill about halfway because pressure will equalize. But in a well ventilated area you can open the bleed valve to relieve pressure until liquid comes out. DH

Glen, I do the exchange thing around here for $18, and may use 3-4 a year. I have seen people do what you are wanting, so I know it can be done, but unless you do a lot of them would it be worth the hassle?
Around here the Meth heads use the 20# bottles to steal anhydrous ammonia from the ag retailers.
Dont want to be asking too many questions about how to bootleg fill the bottles, you may end up with the SWAT team banging on your door.

Yes, you can fill them. I do it all the time. My LP supplier set my tank up with a remote hose and the proper fittings. Cost was around $100, a few years ago. I fill the grille tanks and my tanks for the forklift.

gene, i have maybe half a dozen of the 20 lb tanks and a 100 for my oxy-propane cutting torch. i have a couple potable propane heaters for getting froze stuff started, seems like i always have empty tanks. even if they dont fill all the way, it saves me a trip to town. i'll see if the local FS has a hose. glenn
As you have said you have a wet side on your 1000gal tank. You need to have the pressure drained
down as much as possible on the small tank then turn the liquid valve on. If you just crack the valve on the 20lb tank a little bit it will cool it and help reduce the pressure so you get more in it. Have filled tanks before. hlh

You might have to take a course on filling propane tanks from the supplier. Dave

I do exactly what you're talking about here. I put a little hose and fittings at the grain dryer/burner so I can tap liquid right off there. One day it didn't work because apparently with sunlight/temp. issues I didn't have much pressure differential. So I just make sure the little tank is cool and then fill it when I know the big tank is warm. You can't get it full like when they pump it, but without a spare tank, this works good for me. The meal might be a few minutes late, but we can go right back to cooking.
Yep can be done and not all that hard to do if you have the correct hose set up. Most propane company's have the correct set ups that they will sell you. ALWAYS wear gloves or you will lose parts and pieces of your hands sooner or later. Back in the late 80s I drove fork lift at a place I worked and filled many a tank. Not hard to do once you learn the correct way of doing it

The guy croaked last summer, so I can tell this.
A buddy of mine used to farm with a propane fueled AC D17, back in the 1970's. He had a separate 500 gallon farm propane tank for filling the tractor without paying the road tax. So, he just naturally had a propane fueled pickup and filled the pickup from the tractor tank.
The day came when he hooked the pickup up to the tank and crawled in the cab while the tank filled. Without thinking, he lit a cigarette. Yep, spent a week in the hospital with burns and had to have his pickup repainted.

Many places where it's a tank exchange you don't get a full tank/20 lb. only something like 17.5 lb.
That's why they put the plastic wrap on the tank, the fine print states how many lb. are in the tank.

Never have understood the "tank exchange" thing.
There are plenty of places to fill tanks around here, usually $1.70 or so per gallon, total cost 7 or 8 bucks. Tank exchange is now over 20 bucks everywhere- I've seen as high as $24.95. And you don't get to BS the fill guy either. Soooooo, what's the attraction?

Fewer places to fill, not open nights and weekends, don"t have to worry about tank retest dates ,leaking tank valves. When I worked for propane conpany we would refill a 20 pound cylinder for less than $3.oo.
glennster, I fill my smaller tanks (5 to 20) gal from my big bulk tank. it is the same principal as filling a pickup or tractor tank. After you aquire the fill hose + and unloading valve. You will need a P.O.L.(put on left)fitting to screw into the smaller tank adapters/pipe fittings and a male LP hose fitting, put it all together to make your adapter to fill out of your tank. hook up the hoses, open the bleed on the small tank and fill till you get liquid out of that little hole.
The LP companies do not open the bleed valves when you get your tank filled now days they do it all by wt. Since most end users do not have a pump set up on their LP tanks The You-s and I-s accomplish the same thing by dropping the pressure in the fill tank and letting the fuller nurse tank fill it.
Simply put the liquid in a higher pressure (bulk tank) will go to an area of lower pressure (the fill tank) to try to equalize pressures and volumes. You can be taught by a LP company or learn from a local neighbor who uses LP and fills his own trucks /tractors/tanks.
Hope this helps.

The OPD valved tanks are almost impossible to fill off large tank. I still have old valves on bottles and managed to get some of the old style valves that LP supplier was going to scrap. They were still new in box.
I received a paper warning about the exchange tanks. It said if you do the exchange thing to look at the new tank that you get. Look inside the threads of the fitting and see if there is any turquoise color inside it. When the meth heads put anhydrous in it it will discolor the valve and they can't get the inside of the threads clean. The anhydrous will rot the valve and can cause leaks which causes explosions. If you find any tanks like that you should not take them and notify the company where you are purchasing of the problem. It is purely a safety issue and as we all know enough things can go wrong even when we take precautions. Steven
They came out and filled the propane tank today. I asked him about hooking a bottle up to fill it for the grill. He looked and said the tank doesn't have have wet valve. The place where he hooks up his fill hose is just for vapor according to him and won't fill a bottle. Before it goes into the tank, it has a brass vent looking thing about 2" tall and an inch in diameter. Said we have to empty the tank to add a wet valve.

OPD tank valves have a recessed slotted screw on the side of the valve. This is a bleed valve and if you open it about half turn it will bleed vapor off to allow you to fill tank. DH

The last 20 pounders I filled was to keep from wasting the LP from a Motor fuel tank on a spreader truck a local guy has. I had to change out the liquid valve a HE broke the stem off turning it the wrong way trying to turn the valve OFF. What was left of the stem on the valve was hollow. I was able to drive in a TROX bit to turn it. I have enough combination of fitting I can make up almost ANY adapter. I fill ALL of my NON OPD valve 20 lb LP, I HATE the OPD valves, 20 LB tanks and some of my nephew's before the dip tube hit vapor. I then starter the truck and burned the rest of the LP off. I then replaced the valve. I learned to handle LP on the fly as I bought a LP fuel combine about 12 years ago. I have also had chemistry in school and I understand PV = nRT

can I fill my propane powered ford pick up from my bulk (1000 gal.) tank?
DH in Carolina
Member
Yes as long as the Feds don't catch you for not paying road tax. Be pretty hard to put red dye in propane wouldn't it? DH
Just to clarify this for me: If a bulk propane tank only has a fill valve for the truck to hook to, can you attach a fitting and hose to that to put some propane in a 20# bottle? Just wondering if a full tank would gravity feed/siphon liquid down to a bottle. Or does it have a check valve of some sort? Thanks.

Fill valve does have a checkvalve and you can't withdraw from it. Also you would only get vapor because the liquid level in the tank will only be 80% when filled. DH

Yep have to use the liqiud side of the tank and the other end I got off a old propane grill most grills go from acme tank tread to pipe tread into the regualtor. Made a hose with a valve to shut on and off one end conected to bottom of big tank other is conected to the 20# propane tank. Dont let the propane man see you can do this,
