What is the proper method to test for leaks in an LP-Gas system?

The proper method to test for leaks in an LP-Gas system is to use soapy water to check for bubbles. This technique is widely recommended because it is safe, effective, and simple. When soapy water is applied to the connections and joints in the system, any escaping gas will interact with the soap solution and create visible bubbles, indicating a leak.

This method is non-invasive and does not pose a fire hazard, making it the safest option for identifying leaks in a gas system. The formation of bubbles provides a clear visual cue, allowing for easy identification of even small leaks that may not be detectable by other means.

Using an electronic leak detector is also a valid method, providing a precise detection of gas presence, but it may not be as readily available to everyone, especially in emergency situations. Checking for flames with a match is extremely unsafe and can lead to an explosion or fire, while wiping connections with a tissue does not provide any real indication of leaks, as it is not a method for detecting gas.
