A wet leg is in fact a liquid takeoff ie theres a pipe which goes down into the tank to about 1in up from the bottom. This is connected to a suitable outlet on the tank outside to which your gas co will fit your adapter hose for filling your small tanks. tho how you plan to do thisis up to ou. you normally need a transfer pump to do this. tho you can do it by venting gas from the reciever tank to drop the pressure so the liquid flows from on to theother. A dangerouss thing to do if yournotset up to do it .
However, I plan to build a small fire under the main tank in order to raise the pressure so that I can fill the small tanks. Don't worry I have a fire extinguisher nearby and will have several buckets of water.
Jusme, when I ordered my 300 gallon tank I asked for a 'wet hose'. They charged about a $100. (4 years ago). Works fine in the summer. I wait until the sun shines on the big tank and then offer up the colder 20 lb. bottle. I'm guessing that I get about an 80% fill. What also helps in my case is that the hose is about 12 feet long, and, when I get about 10 feet away the ground is about 1 foot lower. This difference (1 foot) plus the fact that the bottom of the tank is about 1 foot off the ground, gives me about 2 feet of head. BTW, I did pick up a propane pump at a garage sale that is identical to the ones at all the RV filling stations. To data I've had no reason to try it out. Was considering converting one of my vehicles to propane in which case I would need a pump. Have no idea if it works, paid only $5.
But, you do have a point. An open fire may not be a good idea. So, I have decided to drill a 1" hole in the bottom of the tank and put a spigot on it. I think there is some propane in the bottom but it will cool the drill bit when it goes through.

Martin, Ted, engineman1 - push back from the computer & look down at your legs. "jusme" has ahold of them and is pulling.
There's a lot of wacko stuff on this NG, but jusme wasn't being part of it. HE WAS KIDDING!
Sure, that'll work, but it's totally unnecessary. All that's necessary is that the tank have no pressure in it (valve open). With no pressure, no propane of significance will come out & with no oxygen in the tank, it can't burn in there.
To convince my overly cautious SIL, I once drilled a hole in an empty propane tank and held a match to the hole. What I got was a tiny flame fed by a little propane leaking out. Smaller that a candle flame & very soft.
I've worked on many propane tanks in this exact way, e.g., cutting in half with an angle grinder.
Don't try cutting trough a tank with propane in it. Water only. And liquid comes from the top - with a dip tube. The inside pressure pushes down on the liquid and it shoots up from the bottom. Think spray bottle.
If the tank is a big one - you likely already have a gas outlet and a liquid outlet. Likely there already. I'm speaking of the 200 gallon up ones. Likely
200 down to 50 or so.
Many people get killed when working on propane or gas tanks. Be careful.
