Mobil-2 Posted January 29, 2017 Report Share Posted January 29, 2017 Refiller just put 8.4 gallons in my 30lb tank. Filled it until the overfill device stopped the flow. Maximum I have ever seen it take when filling this way is 7.5 gallons. Ambient temperature was 66°F. I am suspicious about the metering at this vendor. My question: What is the most gallons you have ever seen your 30lb tanks take during refill? Link to comment Share on other sites More sharing options...
w4whh Posted January 29, 2017 Report Share Posted January 29, 2017 My 30# cylinder usually takes 6.6-6.7 gallons to fill. However, this morning, at the propane retailer I always use, the attendant filled it to 7.0 gallons. It has never filled to that level before. Ambient temp in Phoenix today is in the high 60s.

Pat & Pete Posted January 29, 2017 Report Share Posted January 29, 2017 A 30 # tank is considered filled at 7 gallons . ( 30 / 4.24 = 7.07 ) That's about 80% of the total volume of that tank . So , there should be room in the tank for 8.75 gallons of propane . BUT , that leaves no room for expansion . Link to comment Share on other sites More sharing options...

My question: What is the most gallons you have ever seen your 30lb tanks take during refill? This is the very reason that most States require that a portable bottle be filled on a scale by weight. As your bottle starts heating up, it will vent. Link to comment Share on other sites More sharing options...
Itinerant1 Posted January 29, 2017 Report Share Posted January 29, 2017 Last 5 times with a empty 30# tank on a scale was always 6.9 gallons Link to comment Share on other sites More sharing options...

chiefneon Posted January 29, 2017 Report Share Posted January 29, 2017 Howdy! You may be also accounting for the propane in the hose used to fill the tank. "Happy Trails" Chiefneon Link to comment Share on other sites More sharing options...
bobsallyh Posted January 30, 2017 Report Share Posted January 30, 2017 Mine will take anywhere from 6.9 to 7.3 gallons depending on temperature and when the automatic changeover kicked in. Link to comment Share on other sites More sharing options...
mptjelgin Posted January 30, 2017 Report Share Posted January 30, 2017 Can you weigh the full tank? That way you'll know if the metering was wrong or if they really managed to stuff 8.4 gallons into your tank. At a unit weight of 4.11 pounds per gallon, a 30 gallon tank should take about 7.3 gallons. So your tare weight plus 30 pounds should be the maximum weight of a full tank.

Truckman Posted January 30, 2017 Report Share Posted January 30, 2017 Usually around 7.0 to 7.1, but the most I ever got was 7.4 gallon. Link to comment Share on other sites More sharing options...
wildmandmc Posted January 30, 2017 Report Share Posted January 30, 2017 That little bit extra could be a way bit to much. Link to comment Share on other sites More sharing options...
Mobil-2 Posted January 30, 2017 Author Report Share Posted January 30, 2017 Couldn't find a public scales for something this size in Yuma but I did the hot water test and sure enough it's full all the way to the top. No space so I guess my valve is faulty. Link to comment Share on other sites More sharing options...
bobsallyh Posted February 2, 2017 Report Share Posted February 2, 2017 Mobil-2, if you had the tank filled in Yuma, which outlet filled it? Link to comment Share on other sites More sharing options...
Bill B Posted February 2, 2017 Report Share Posted February 2, 2017 Net weight on the side of the tank collar (usually 25.4#) + 30 # = 55.4 # full. I use a bathroom scale. Link to comment Share on other sites More sharing options...
gjhunter01 Posted February 2, 2017 Report Share Posted February 2, 2017 If the bottle weighs more than 55 lbs, then just bleed some gas off by hooking it up to a grill or something and let it burn for awhile. The OPD valve has a float inside to prevent overfilling the tank and the only way the bottle could be overfilled is if the float broke off, quite unusual. The bottle should be inspected before refilling, infact paint the words damaged on the bottle incase it ends up in someone else's hands.

Bill B Posted February 2, 2017 Report Share Posted February 2, 2017 UNLESS - the guy used the spitter outlet and did some fancy stuff to "give you a full bottle". If you fill it upside down you can over fill easy. Just saying, I always stand there to make sure no "interesting" things go on. One would think but ..... one guy set them on the table sideways so that he didn't have to bend over, valve would never close. Use as much as you can soonest, and try a different place before you "condemn" the tank and have the valve changed. Always be watchful of 'something different' going on. It may not be in your best interest. Link to comment Share on other sites More sharing options...
kb0zke Posted February 3, 2017 Report Share Posted February 3, 2017 I hate to say it, but I'd be suspicious of the metering at that place, too. You pay by the gallon, so if they can have the meter rigged to show an additional gallon they profit by that much. You might want to contact the State. Go to any gas station and copy the number down from a pump. BTW, last year we needed propane in our motor home, so I checked with a propane store on the main drag to see if they could fill us (not all places can or want to deal with a MH). I went in to ask, and the clerk answered my questions but kept me visiting. When the other person (clerk) left the clerk I was talking to told me not to buy there as the person who did the filling didn't know what he was doing. One time he actually got the hose frozen to the tank. I went to the other place in town and asked my questions there. When I mentioned that I had been referred by their competitor I was told that that happened every once in a while. They also have gotten business from the first place because of problems and customers not wanting to go back. Pay attention to what's happening, and if something doesn't seem right say something.

gjhunter01 Posted February 3, 2017 Report Share Posted February 3, 2017 In Texas the Rail Road Commission will shut down a LP station if they get caught using a rigged meter or unsafe filling procedures, including not using a scale. The RRC will do spot inspections and follow up on all customer complaints. The consequences are pretty strict in Texas anyway and few LP stations would risk their companies future by breaking rules or cutting corners.

kayakbob Posted February 8, 2017 Report Share Posted February 8, 2017 My fill station has a large sign stating that is a federal offense to fill a tank with more than 80% of its capacity ! Link to comment Share on other sites More sharing options...
