Backflow Preventers

Backflow preventers restrict water from flowing backwards into a water supply pipe, preventing contamination of drinking water. They're utilized in industrial settings where chemicals are connected to water lines, as well as in municipal water systems to keep unwanted liquids and solids out of piping.
