Cylinder refill and exchange covers the small stuff that keeps grills, patio heaters, camp stoves, and forklifts running: swapping an empty 20 lb tank for a full one, or filling the tank you already own on the spot. Tampa has 76 businesses listed here that offer this service, ranging from hardware stores and gas stations with an exchange cage out front to dedicated propane dealers who fill cylinders by weight while you wait.
The two options work differently. Exchange means handing over your empty tank and taking a pre-filled one from a locked cage, usually at a fixed price regardless of how much propane was actually left in your old tank. Refill means the seller weighs your empty cylinder, fills it to the correct level for its size, and charges by the gallon, which almost always gets you more propane for the money if your tank was truly empty. Refill also lets you keep the same tank, so you're not stuck with whatever condition the exchange cage hands back.
When picking a supplier, look for a business that fills cylinders on certified scales, checks the tank's recertification date (tanks need requalification every 12 years, or 5 years after that), and inspects valves and gaskets before handing it back. A supplier who refuses to fill an out-of-date or damaged tank is doing it right, not being difficult.
