Question

Quizplus · Accepted Answer

Both nitrogen gas and headphones and a smoke machine are common tools for diagnosing leaks in an evaporative system. Nitrogen gas can be used to pressurize the system without introducing moisture, and the headphones help listen for the escaping gas. A smoke machine introduces smoke into the system, and the smoke escaping from leaks makes them visible.
