How often must the automatic line leak detector for pressurized piping be tested?

1. Monthly.

2. Annually.

3. Every 3 years.

4. Every 5 years.

The correct answer is: Annually.

The correct answer is that the automatic line leak detector for pressurized piping must be tested annually. Regular testing is essential to ensure that these systems function properly in detecting leaks, which is critical for environmental protection and compliance with regulations. Annual testing helps to maintain the integrity of the leak detection systems and ensure that they operate effectively, minimizing the risk of leaks from pressurized piping that could lead to contamination of soil and groundwater. Other frequencies, such as monthly or every few years, do not align with the prescribed standards for leak detection testing in many regions, including California. Monthly testing could impose unnecessary operational burdens and costs, while testing every 3 or 5 years could increase the risk of undetected leaks during those intervals. Therefore, the annual testing reflects a balanced approach that aims to ensure safety and regulatory compliance without being overly burdensome.
