How often should backflow preventers be tested?

Backflow preventers are critical devices used in plumbing systems to prevent contaminated water from reversing flow back into the clean water supply. Testing these devices annually ensures they are functioning correctly and effectively safeguarding public health. Regular testing helps identify any wear and tear or malfunctions, allowing for timely repairs and maintenance.

While some systems may recommend different testing intervals based on specific local regulations or usage conditions, the annual testing standard is widely accepted as a best practice. This practice minimizes the risk of cross-contamination and ensures compliance with health and safety regulations. Always following the most stringent testing requirements helps ensure that drinking water remains safe and free from potential pollutants.
