What is the recommended frequency for inspecting backflow preventers?

The recommended frequency for inspecting backflow preventers is at least once a year. This regular inspection schedule is crucial because backflow preventers are vital components in water supply systems that prevent contamination from polluted water flowing back into the clean water supply. Annual inspections help ensure that the devices are functioning correctly, maintaining the safety and quality of the water supply.

Inspecting backflow preventers yearly allows for the timely identification of any potential issues such as wear and tear, sediment buildup, or mechanical failures that could compromise their effectiveness. Implementing a consistent inspection routine helps comply with health and safety regulations and mitigates the risk of cross-connection hazards, which could lead to severe public health consequences if left unchecked.
