For the second year, National Backflow Prevention Day on August 16, 2022, recognizes the role of backflow prevention and cross-connection control and those who install, maintain, and test backflow preventers. It marks the day in 1933 when a backflow incident occurred at a Chicago hotel resulting in 98 deaths and 2,000 illnesses. The incident led to the founding of the Foundation for Cross-Connection Control and Hydraulic Research and to new safe plumbing regulations for backflow assemblies. Plumbing & Mechanical marked the day by asking for backflow prevention “selfies” and photo submissions.
