How to detect a very small natural gas leak that is not easily visible

Minor leaks can be difficult to detect, especially in open or well-ventilated spaces. Proper diagnosis requires a combination of methods.

Local scanning

The electronic detector is moved slowly around all potential connections, not just in the most obvious spots.

Foaming agent

On suitable surfaces, it helps to confirm very small losses through sustained bubble formation.

Section isolation

In a larger network, gradual isolation helps narrow down the search area.

Pressure decay

If the section is suitable for such a test, pressure monitoring can confirm that there is a loss even if the exact point has not yet been located.

Beware of air currents

Air currents can carry gas away from the actual leak point and make detection difficult.
