For effective installation, what should be checked regarding the shear valves?

The focus on height adjustments when checking shear valves is crucial for effective installation because shear valves are designed to operate at specific heights to ensure proper function and protection. Shear valves are safety devices used in underground storage tank systems that protect against leakage due to accidental damage, such as vehicle impacts. If the shear valve is not installed at the correct height, it may not activate as intended during a shear event, leading to potential leaks or catastrophic failures.

This emphasizes that the correct positioning of the valve plays a significant role in both its operational efficiency and the overall safety of the storage system. Ensuring that the shear valve is at the proper height allows for appropriate functionality, activating when needed to prevent environmental contamination and maintain compliance with safety regulations.
