How do I know if my LPG cylinder is leaking?

You may smell gas (a rotten-egg odour), hear a hiss near the regulator, or see bubbles when you brush soapy water on the joints. If you suspect a leak, turn off the valve, open windows, avoid switches and flames, and move the cylinder outdoors.

What should I check before using a cylinder?

Check the cylinder seal and serial, the regulator and hose for cracks, and do a soapy-water leak test on the connection. The checklist above walks you through each step.
