Backflow Preventers, Pressure Reducing


Zurn Pressure Reducing Backflow Preventers are specialized water control assemblies that combine backflow prevention technology with pressure regulation capabilities, serving dual functions critical to municipal water system management and public health protection. These devices prevent contaminated water from flowing backward into the public water supply while simultaneously reducing excessive water pressure that could damage residential plumbing, cause water waste, or create system inefficiencies in high-pressure distribution zones. Water utilities strategically install Zurn pressure reducing backflow preventers in areas with elevated water pressure conditions, such as hillside developments or near pumping stations, to maintain optimal system pressure, protect customer plumbing infrastructure, and ensure reliable backflow protection throughout the distribution network.
