Wilkins Regulator 3-375ASTOSY Backflow Preventer 3 Inch

Product Description

The WILKINS REGULATOR 3-375ASTOSY is a 3-inch reduced pressure principle backflow preventer designed to protect potable water supplies from contamination due to backflow or back-siphonage. Reduced pressure principle devices maintain a differential pressure zone between two independently operating check valves, with a hydraulically operated differential pressure relief valve positioned between them. This assembly provides a high level of protection for cross-connection control applications and is installed by licensed plumbers and water system contractors. It is appropriate for use in both commercial and industrial piping systems where backflow protection is required by local code.

The 3-375ASTOSY is sized at 3 inches, making it suitable for larger-diameter water service lines commonly found in commercial buildings, industrial facilities, irrigation systems, and fire suppression supply lines. Installation requires adherence to local plumbing codes and cross-connection control regulations, which typically mandate periodic field testing by a certified backflow assembly tester. Where required, local water authority approval of the assembly and its installation location is standard practice.

Key Features

• Reduced pressure principle design provides high-hazard backflow protection for potable water systems
• 3-inch connection size suited for larger commercial and industrial water service applications
• Dual independently operating check valves with a differential pressure relief valve between them
• Designed to meet cross-connection control program requirements where reduced pressure assemblies are mandated

Compatibility

Designed as an OEM-style reduced pressure principle backflow preventer assembly for 3-inch commercial and industrial water service piping applications.

Installation Notes

Installation must be performed by a licensed plumber in accordance with applicable local plumbing codes, the International Plumbing Code, and any authority having jurisdiction over cross-connection control. Shut off the water supply completely before installation and verify that the system is depressurized before working on any connections. The assembly should be installed in an accessible location to allow for mandatory periodic testing and maintenance by a certified backflow assembly tester. Do not install in a submerged or flooded environment unless the assembly is specifically rated for such conditions.
