The 3 inch Maxim Reduced Pressure Zone Backflow Preventer Assembly features groove couplings for straightforward installation and pipe alignment. It is designed for horizontal Z pattern installation and connects to matching 3 inch grooved piping systems. Ensure adequate clearance is maintained around the valve for inspection, testing, and servicing.
This Maxim™ 3 inch lead free reduced pressure zone backflow preventer assembly is designed to prevent the reverse flow of fire protection substances and water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and/or backpressure in accordance with national plumbing codes and water authority requirements.
This assembly is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards. Its extremely compact design and lighter weight than traditional assemblies make it suitable for installations requiring small enclosures and easier handling. It is approved for horizontal Z pattern installation, ensuring proper flow direction.
