What is the correct method to perform a leak test on a propane system?

• A. Spraying with water only
• B. Mixing soap and water and applying it to joints
• C. Using an electronic leak detector
• D. Soaking the joints with gasoline

Answer: (B)

The correct method to perform a leak test on a propane system is to mix soap and water and apply it to the joints. This technique is effective for identifying leaks because the soap solution creates bubbles when it comes into contact with escaping gas. If there is a leak, the gas will escape through the joint, causing the soap solution to bubble up, which visually indicates the presence of a leak. This method is widely recommended because it is a safe, simple, and cost-effective way to check for leaks in various piping systems. It allows technicians to quickly pinpoint potential problem areas without the need for specialized tools or equipment. Using only water would not provide the same visual indication as the soap solution, making it less effective. An electronic leak detector is indeed a viable option in some situations, but it requires the right equipment and training to use effectively. Soaking the joints with gasoline is extremely dangerous and inappropriate for leak detection, as it could lead to fire hazards and does not provide a reliable method for finding propane leaks.
