What Is Backflow and Why Is It Dangerous?

Backflow usually happens due to a sudden drop in water pressure. This can be caused by events like a burst main, firefighting activity, or excessive water use in one area. When this pressure drop occurs, contaminated water from external sources — like irrigation systems, pools, or industrial equipment — can be sucked back into your clean water lines.

This kind of contamination can pose serious health risks, especially in properties that use chemicals, pesticides, or other hazardous substances. That’s why backflow prevention is more than just a plumbing requirement — it’s a public health necessity. Backflow devices are typically required in both residential and commercial properties where there is a medium to high risk of contamination. This includes places like cafes, medical clinics, salons, workshops, and even homes with irrigation systems or rainwater tanks connected to mains water.
