What is a Backflow Valve?
A backflow valve is a device that prevents contaminated water from flowing back into the clean water supply. This is important because backflow can contaminate the clean water supply, making it unsafe to drink or use.
How Does a Backflow Valve Work?
Backflow valves work by using a series of check valves to prevent water from flowing in the wrong direction. When water flows in the correct direction, the check valves open and allow water to pass through. However, if water starts to flow in the wrong direction, the check valves close and prevent contaminated water from entering the clean water supply.
