backflow prevention

Backflow prevention is a safety measure used in plumbing systems to stop contaminated water from flowing backward into clean water supply lines. It works by installing devices, like backflow preventers, which allow water to flow in only one direction. This is crucial in preventing pollutants from entering drinking water, especially in situations where pressure changes can occur, like during a fire or pipe break. By maintaining a barrier between clean and dirty water, backflow prevention systems help protect public health and ensure safe drinking water for everyone.
