The concept of a backflow preventer is simple. It keeps the water from your pressurized fire sprinkler water line from flowing back into the municipal water line. This could happen if the municipal water line suffers a loss of pressure. A Backflow Preventer would ensures that there is no polluting of the city water line.
Like all fire protection equipment, backflow preventers require annual inspections and will need to be serviced and maintained every year. Sunland has backflow prevention experts on staff that can help you with backflow installations or service.
