Blue Rhino uses their own proprietary valves, so that you cannot have the tanks filled elsewhere
First, a 20 lb tank cannot hold 20 lbs of propane, simple basic math with a little physics thrown in. Second, I have not bought a new propane tank for my grill or smoker at home for 20 years. When my tank ages out, I pick up a Blue Rhino, rip the plastic wrap off and use it, fill it, use it, fill it over and over until it needs recertification and then turn it in at Blue Rhino and do it all over again.
