You can usually smell a gas leak. Natural gas is odourless, but the gas companies add a chemical that smells like rotten eggs so you will be able to detect it in case of a leak. Other signs that you may have a gas leak are:
- A hissing or roaring noise coming from the pipes
- Static electricity sparks coming from the outlets or appliances
- The pilot light on your furnace goes out
- Water boils rapidly on the stovetop even at low heat
- Sudden changes in your gas bills
