Refilling your propane tank is a better value than an exchange. With an exchange tank, you're not only losing what's left in the tank, but you're also paying more for less fuel since exchange tanks aren't filled to the maximum legal limit. A 20lb tank often only contains 15lbs of propane when you do an exchange. At Safe and Sound Storage, we'll fill your propane tank all the way up until it's full. Getting you more propane for the cost and more overall use out of your tank. There's no tank too big or too small for us to fill, if you can get it to us then we'll be happy to fill it for you.
