Restricting the movement of a broken bone in your leg is critical to proper healing. To do this, you may need a splint or a cast. And you may need to use crutches or a cane to keep weight off the affected leg for six to eight weeks or longer.
(Minimums vary by location and tank size, and can range from 100-1,500 gallons.) More often, the propane company charges a fee of anywhere from $25-$250 a year but averaging around $75-$130 annually, depending on local rates, the size of the tank and whether it's aboveground or underground.
Just as a note to all of you. If you trade in you are only getting 13 - 15lbs of propane in the 20lb tank for about 18.00 - 21.00$. It cost me 12.00 for 20lbs to have my tanks refilled. Most rental places refill tanks as well as Ace Hardware.
