What is Backflow and Why is it Dangerous?
Backflow occurs when changes in water pressure cause water to flow in the wrong direction, allowing contaminants like chemicals, pesticides, and sewage to enter your clean water supply. This can happen during a water main break, a firefighting event, or when high-pressure systems back up into the main lines.
These events pose serious health risks and can lead to city code violations if left unchecked. That’s why professional testing and certified backflow prevention services are critical for homes, businesses, and unit properties.
