National Backflow Prevention Day began in 2021, started by Watts Water Technologies. They wanted to bring attention to the important role of backflow preventers.
These devices keep dirty water from entering clean supplies.
The company chose August 16 to mark a major plumbing disaster in 1933. At the Chicago World’s Fair, a large backflow event caused thousands of people to fall ill.
Nearly 100 people died after staying at hotels where contaminated water had entered the pipes. That tragic mistake led to big changes in plumbing rules across the country.
The day isn’t just about one event—it’s about what we’ve learned since then. Every year, workers install and inspect valves that stop water from flowing the wrong way. National Backflow Prevention Day helps more people understand why this work matters.
It also gives thanks to those who protect our drinking water. Schools, cities, and plumbing companies use the day to teach, train, and raise awareness. The goal is simple: keep water safe for everyone.
Clean water doesn’t stay clean by chance. It takes the quiet work of experts and the support of people who care. That’s why this day continues to grow in meaning each year.
Get a Home Inspection
Hire a licensed plumber to check your backflow preventer. Many people don’t know if they even have one. A quick visit can uncover issues before they grow. Safe plumbing starts with knowing what’s already in place.
Thank a Technician
Call, message, or post online to appreciate your local plumbing pros. They work hard behind the scenes. Their routine tests and fast fixes keep your water clean. A simple thank-you means more than you think.
Learn the Basics
Watch a short video or read a quick article about how backflow happens. Choose easy-to-follow guides with clear visuals. The more people understand, the more likely they are to care. Knowledge helps everyone stay prepared.
Share a Reminder
Post a tip or fun fact on social media. Use humor or a short story to grab attention. Keep it casual but clear. These messages stick better when they feel real and relatable.
Support School Programs
Donate to plumbing trade schools or student training programs. Some students can’t afford tools or classes. Helping them helps your entire community. Safe systems need well-trained hands to build and maintain them.
