California ICC UST Service Technician Practice Exam

Single walled suction piping must be tested at least every how many years?

1. 2 years

2. 3 years

3. 4 years

4. 5 years

The correct answer is: 3 years

Single walled suction piping must be tested at least every three years to ensure its integrity and compliance with safety regulations. The requirement for testing this type of piping stems from the need to prevent potential leaks and environmental hazards associated with underground storage tanks (USTs). Regular testing helps identify any deterioration or damage that could lead to the release of hazardous substances into the environment. While shorter testing intervals might seem more cautious, the three-year requirement strikes a balance between regulatory compliance and operational practicality. It ensures that the piping is adequately assessed without imposing overly burdensome requirements on facility operators. Failing to adhere to this timeline could result in increased risks and potential penalties from regulatory authorities.
