Quick answer
A gas refill means a dealer fills your own LPG cylinder, so you keep the same cylinder, while a gas exchange means you hand in your empty cylinder and take away a full one that has already been filled and checked. Both are safe when done at a reputable dealer, but only cylinders in good condition and within their test date should be filled.
Exchange is often quicker and gives you a cylinder the supplier has inspected, while refilling keeps a cylinder you know. Check what each dealer offers and ask how they inspect cylinders.
Step by step
- Check your cylinder for rust, dents, bulges, a damaged valve or a missing collar before taking it in.
- Find the test or inspection date stamped on the cylinder, usually on the collar, and ask the dealer if it is still in date.
- Choose a reputable gas dealer and ask whether they refill, exchange or both for your cylinder size and brand.
- Transport the cylinder upright and secured, with windows open, and do not leave it in a hot vehicle.
- At home, check connections for leaks with soapy water, never a flame, and use a registered installer for fixed installations.
What to check
- Cylinder condition and test date before filling
- That the valve is closed and the cylinder is sealed when you collect it
- Whether the exchange cylinder comes from a recognised supplier
- That fixed gas installations are done by a SAQCC Gas registered installer
Common mistakes to avoid
- Filling a damaged, rusted or out-of-date cylinder
- Refilling at informal or unlicensed outlets
- Storing cylinders indoors, lying down or near heat
- Testing for leaks with a flame
