how to install a wet leg on bulk propane tank

Hello-

I moved to a new place and own my 500 gallon LP tank. Want to install a wet leg to fill my own 20 pound grill tanks. My tank was made in 2002 and has the dip tube port on it. I bought a REGO 7590U-10 adapter to fit on the wet leg valve on tank. Also have the angle valve that attaches to the REGO 7590U-10. Before I install it, can someone who has done this explain how to attach it to the 500 gallon tank and disconnect it? Seems that when you screw the adapter onto the tank, it looks like it will depress the valve? Once I attach it, does it have to stay on the 500 gallon tank until it is empty to remove? I do understand how to fill the 20 pound tanks with the bleeder valve and weight, just not about attaching the adapter to the big bulk 500 gallon tank. Please explain. I am well aware of the risks, and want to be sure how to do this procedure correctly. I have read online that people do this all the time. Thanks in advance!
 
Assemble your adapter and valve, then just screw it
on. It will unscrew if you need to take it off,
the shut off closes before the threads separate. You
can get a little burst of LP as it comes apart. I
also have a valve on the end of my hose, so I don't
get alot of gas when disconnecting the little tank.
 

I want to do the same thing, but I am getting NO cooperation from my propane supplier. He told me the only way I could have it is IF I owned the tank, but they do NOT sell tanks, they only rent them. Plus, he told me that even if I OWNED the tank, he would NOT fill it if I had the adapter on there.

I asked him what would happen if I bought a propane powered tractor, and needed to fill the tank. He just gave me a dirty look and said nothing.

What are these propane companies afraid of?
 

Thanks for the reply Moresmoke. I suppose when you want to take it off, the liquid LP in the valve itself will take a bit to boil off and vaporize when taking adapter off the tank? Thanks!
 
"What are these propane companies afraid of?"

I'm guessing pretty soon we won"t even be able to buy the stuff!

Several years ago, a local bed and breakfast had some furnace trouble, and had an outfit that has been around a long time and gotten quite big work on the propane furnace. (NO inexperience here!)

The second or third service call trying to fix it, the serviceman went down to the basement to work on it and (one way or another) a propane explosion was touched off that blew the windows out of the house and shifted the house on it's foundation.

Fortunately, the serviceman and owner weren"t badly hurt.

The owner's insurance company paid off, then sued the Co-op that had supplied the propane alleging there wasn"t enough odorant in the propane to alert the serviceman to the presence of propane in the basement. (The propane supplier had NOTHING to do with the furnace.)

I never did hear how that turned out.

Another instance... a large privately-owned truck shop, also near me, was destroyed by an explosion, followed by a fire. Apparently, insurance also paid off. That was maybe 2 years ago, and he has since rebuilt.

Story is he stopped by the Co-op (next door neighbors to the previously mentioned Co-op) just a few days ago and asked if they would fill the propane tank by his house so the wife didn"t have to deal with a lack of hot water when the propane water heater went out.

They were INCREDULOUS that he would stop in to do business with them. Turns out THAT insurance Co. is suing that Co-op, too, even though they only supplied gas, not the furnace, not did they ever work on it or touch it. The shop owned claimed to be completely "in the dark" about his insurance Co. suing to recover their loss.

Seems like they are involving a couple of local guys who may have repaired the guy"s (gravel hauling) semis, as well.

So that"s TWO examples in a county of 2500 residents of propane suppliers being sued.

Kinda explains why the are getting nervous, doesn't it!

I kind of had an idea it might be the insurance companies behind it all. They are becoming WAY too powerful. I may not own the tank, but I DO own the propane inside that tank, and I SHOULD be able to access that propane in any way I deem appropriate.
 

Rustyfarmall-

I agree with you totally. The propane is yours, why should you have to go somewhere else and pay more to get it when you could do it yourself from home. Insurance and lawyers created this mess.
 
What if the WW2 generation had the fear mongering nanny-state attitude that seems so common today? I don't worry about propane in tanks, I worry about gasoline in plastic 5 gallon cans!

Fortunately out local company will fill tank, tractor or whatever if I ask them to.

The same company that will NOT install a wet leg for me also WILL NOT fill the tank on a propane powered pickup truck, even if you drive it over to them. I asked.
 
Once you put the valve on you never take it off,because there is no need to.When you start talking about removing it each time,I don't think any supplier would touch(fill)that tank.I think maybe you need to read-learn more on what you want to do before you begin,because you need more equip.then you mentioned.
 
Ask the propane company if you can get a pumping
station then you could fill your gas grille tanks
your pickup truck and your tractor
 
You guys all point angry fingers at the insurance companies, but I bet $100 the first thing that each and every one of you would do is run crying to the insurance company if there was a mishap with property damage.

The WWII generation would have no choice but to eat the loss, and most of them couldn't even come close to being able to afford it. Many people ended up in the "poor house" through no fault of their own because they did not have insurance.

If the WWII generation had insurance to fall back on, they surely would have done so. They would not have walked away from everything they had worked their whole lives for.
 
(quoted from post at 06:35:16 07/18/14) BTW, I would find a different supplier.

I had been a PelGas customer for 16 years. They refused to install the wetleg, so I switched to the local Co-op. The Co-op won't do it either. There is only one other supplier in this area, and that one has a very bad reputation.
 
Agree with mkirsch - find a different supplier. A few years ago Amerigas purchased a small supplier I did business with and immediately raised prices, got picky about everything, and stacked fee after fee on the prices. I questioned all this, and the receptionist said "there is nothing I can do". I said I can, I will purchase my own tank, and have you pick up your tank. She informed me that is fine, but they will also charge me to pump out the tank and pick it up. I wished her luck in getting it since it is in fact their tank, but I would burn MY gas out prior to calling. Then I made the mistake of purchasing a tank without a "tag". Just try getting a supplier to fill one of those. I did eventually find a supplier that was actually in business to sell propane and he has been filling ever since, but I know sooner or later they will sell out and I will be out of luck. In the meantime it seems to work fine without the tag. Again, probably insurance reg's making the suppliers abide by all this.
 
So how are the Greenies supposed to promote alt fuels... Hydrogen, CNG and LNG are under way more pressure than good old propane. You almost have to laugh at the situation.

Exactly!! Makes a guy think that these propane suppliers are scared of their own shadows.
 
I would be curious what the reason you folks are telling the gas companies why you are wanting a liquid valve setup.To refill small tanks would be a good reason for refusal.I have 8 1000s and 2 500s,that all have liquid withdrawal valves and am getting another 1000(wk or two)and it will have a liquid valve on it.I have 3 suppliers and no one has said a word.But we only pull vapor off two tanks(shop & a house)rest are on liquid lines.

How is filling a 20 pound tank any different from filling a tank on a tractor? And for what it is worth, when I asked the Co-Op guy about the wet leg, I mentioned that I might some day be owning a propane powered tractor, and I would like to have a source for refueling it without taking it to town. I was told in no uncertain terms that not only would he not install the wetleg, but niether would the Co-Op refuel the tractor, even if I brought it to them.

I also watched as the Co-Op filled 2 brand new 20# grill tanks for me. The method they used is exactly the same as what I want to do, but I want to do it at home, with MY propane.
 
Not really any difference,except the way it is looked at.Ag.vs homeowner.One of our suppliers since 1948 gave us a pump and equip.to help with transfer on our tanks.In yours or my defense The Propane business is one of the most screwed up deals out there,each one is his own little empire.(rules-practices pricing)

I agree on the average homeowner philosophy, but then the average homeowner is using natural gas and does not have a 500 gallon propane tank setting in his backyard. Instead, the average homeowner with a backyard grill either uses the small propane tanks, or has the grill connected directly to the natural gas line.
 

After this incident every LP regulation in North America was given another look. In Canada , Ontario in particular. Whole entire bureaucracies, agencies and empires grew from this mess. Politicians, legal firms, consulting firms and bureaucrats around the entire country. They watched and learned how to build lucrative and unquestioned empires after the Walkerton Water Crisis.

They're running scared because all it takes is one BillyBob or Bubba who thinks he knows it all to blow himself and half his neighborhood up to ruin their business. Cuz, even though BillyBob blew himself up through his own stupidity, the grief stricken Mrs. BillyBob will blindly follow the advice of the first personal injury attorney that knocks on the door, and sue everyone.

Since they can't tell you apart from BillyBob and Bubba, no matter how much you pound your fist on their counter and scream, "I know what I'm doing!" (because of course BillyBob and Bubba do the same thing), they won't do it for anybody.

Speaking of BillyBob and Bubba, I think both of them are already working for some of the local propane suppliers.

Keep in mind NFPA 58 which specifies code for propane specifies that wet legs are treated the same as a dispensing station, meaning it is required to have the same safety regulations which would apply to a gas station who dispenses propane even if its on a private residence. Most likely your setup is not compliant (Emergency shut off etc) This is why propane companies dont like these set ups as they dont have control and cant ensure they are compliant on somebodys personal property.
