Which device is used to check for leaks in LP or natural gas lines?

• A. Soap solution
• B. Gas meter
• C. Leak detector
• D. Smoke tester

Answer: (C)

Detecting gas leaks requires a device that senses the presence of gas in the air and alerts you. A leak detector is designed for this purpose, continuously monitoring for methane or propane and sounding an alarm when gas is detected, which makes it the most effective tool for checking LP or natural gas lines. Soap solution can reveal leaks by bubbles when you spray it on joints, but it’s a manual, spot-check method and not ideal for ongoing monitoring. A gas meter measures how much gas is being used, not whether a line is leaking. A smoke tester isn’t the standard method for diagnosing gas-line leaks and can be less practical and safe for this purpose. So the leak detector is the best choice because it is purpose-built to detect and alert to gas leaks.
