What is the correct method for checking for leaks around a fitting?

Using leak detector solution is the most reliable method for checking for leaks around a fitting. This solution is specifically formulated to detect the presence of gas or air leaks. When applied to a fitting, the solution will form bubbles if there is any escaping gas, providing a clear visual indication of a leak. This method is effective because it allows for precise detection, ensuring safety in environments where leaks can pose significant risks.

While conducting a visual inspection can help identify obvious issues, it may not reveal smaller, less detectable leaks that a detector solution would catch. Similarly, wiping with a cloth does not provide any indication of a leak; it merely cleans the area without testing its integrity. Listening for sounds can sometimes identify a leak, but it is not always reliable and can easily lead to missed leaks, especially in noisy environments. Thus, employing a leak detector solution ensures both accuracy and safety when inspecting fittings for potential leaks.
