One of the first ways and most common ways to detect a gas leak is by its smell. A gas leak smell will have a very strong odour. Special care should be taken as too often people will confuse the smell of gas for something else. Another way to find signs of a gas leak is by using a soap solution to detect it. Once you mix the soap solution apply it to the joints on the LPG pipes and this will confirm if there is a leak.

Plumbers also have special equipment to assist with this process. For cases where the leak is present at the valve the standard soap test may not work and it will be necessary to call the services of an expert.

Finally, you may not be able to locate all the plumbing supplies that are necessary for detecting gas leaks.
