National Backflow Prevention Day is observed every August 16 in the United States, highlighting the importance of backflow preventers and the professionals who maintain them. This day aims to raise awareness about protecting drinking water from contaminants. Activities typically include educational initiatives, such as webinars and certification discounts offered by organizations like ASSE International and the American Water Works Association (AWWA). Local plumbing businesses may provide free inspections and distribute educational materials to their communities. Additionally, manufacturers like Watts Water Technologies and Zurn Water Solutions emphasize their commitment to safety standards and product innovation. The day serves as an opportunity to appreciate the efforts of those in the plumbing and water safety industries.
