backflow preventers

Backflow preventers are devices installed in plumbing systems to stop contaminated water from flowing backward into clean water supplies. This reverse flow can occur due to pressure changes or disruptions, risking pollution of drinking water. The preventer creates a barrier—like a check valve—that only allows water to flow in one direction. They are essential in systems connected to irrigation, industrial processes, or fire sprinkler systems, ensuring safe, uncontaminated drinking water for homes and businesses. Properly maintained backflow preventers are vital for public health and water safety.
