How to Refill LPG Gas Cylinder
Propane is stored in liquid form in high-pressure tanks, and it turns into a gas when its pressure is lowered by opening the valve. Depending on the type of propane tank you have, you may be able to fill it on your own when it’s empty from a larger supply tank. Before you fill your propane tank, be sure to check that the tank is in good condition and that filling it yourself is legal in your area. If you can fill your tank, remember to be extremely careful since propane is flammable and could ignite!
