My local refiller recertifies free for regular customers,but I just replaced a 30# that had already been recertified twice and was looking a little worse for wear. The refiller charged me $50 for a purged and filled new cylinder and will dispose of the old cylinder. He used a large bolt cutter to destroy the threaded part of the valve to make it unusable.
When you get one that's in too bad shape to be recertified, simply take it to one of those Blue Rhino exchange places and trade it in, $18.00 you get a Newer tank full of gas.
I get mine recertified. Aren't tanks from Blue Rhino a 15# fill?
"Actually" a 20 lb cylinder by design would hold 25 lbs of propane if it were completely filled. 20 lbs of propane is 80% of 25 lbs. The reason there is extra volume is so the liquid can vaporize into a gas otherwise only liquid would come out of the cylinder until enough liquid came out the gas would begin forming.
So when blue rhino fills them with 15 lbs they are actually putting 75% of 80% of what the cylinder can actually hold. Blue rhino initially got sued for misleading people thinking they were getting 20 lbs of propane in the cylinders they were refilling. Initially they were doing it to rip people off. Now they say it's for safety reasons when they refill the used cylinders with only 15 lbs.
