Gas Leak Detection
There are a variety of ways to detect gas leaks, including:
- The Smell Test: Natural gas is colorless and odorless. The reason you may be able to smell a gas leak is because a chemical called mercaptan is added to give it a noticeable odor. Most people think it smells like rotten eggs. If you smell rotten eggs you may have a gas leak that needs immediate attention.
- The Sight Test: An appliance that’s working properly should have a crisp, blue flame. If you see a yellow or orange flame you might have a gas leak. Additional signs of gas leaks are soot or scorched areas on the backside of appliance, pilot lights that won’t stay lit, or an excessive amount of condensation on windows.
Not all gas leaks are obvious. Two more ways check for these leaks are using an electronic gas detector or the bubble test. Gas detector can be expensive and may require some special knowledge to use them. The bubble test is performed by adding liquid soap to water then rubbing the solution onto gas fittings and lines. Leaks will cause the liquid to bubble.
