Reduced pressure zones (RPZ) are complex backflow prevention devices that are used in larger plumbing systems or where the risk of contamination is high. RPZ devices consist of two check valves and a relief valve, which creates a zone of reduced pressure between the check valves.
When choosing an RPZ backflow prevention system, you can consider things like:
