How often should backflow devices be inspected visually?

Backflow devices should be inspected visually at least once a year or whenever there are changes in the system to ensure they are functioning properly and to prevent any potential contamination of the potable water supply. Regular inspections are vital because these devices are designed to protect against backflow, which can occur due to changes in water pressure or other system modifications. If there is a change in the plumbing system, such as new equipment installation or repairs, it is essential to inspect the backflow device to confirm its integrity and efficacy in preventing backflow incidents. Adhering to this annual inspection routine not only complies with regulatory standards but also ensures the safety of the water supply by identifying any issues before they become serious problems.
