The SLOAN 323210 is a vacuum breaker designed for use with flushometer-style flush valves in commercial and institutional plumbing systems. Also known by the model designation V-500-AA, this component prevents backflow by breaking the vacuum that can form in the supply line after a flush cycle, protecting potable water from contamination. It is constructed from brass with a polished chrome finish, meeting the durability and appearance standards expected in high-use restroom environments. Licensed plumbers and commercial plumbing contractors are the primary installers of this component.
This vacuum breaker is intended for use with flushometer flush valves, the type commonly found on commercial water closets and urinals in office buildings, schools, hospitals, and other high-traffic facilities. Domestically manufactured, it is suited for new installations and maintenance replacements in existing flushometer assemblies where backflow protection is required by plumbing code.
Designed for use with Sloan flushometer flush valve assemblies where a vacuum breaker is required as part of the valve assembly.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and relieve line pressure before removing or installing the vacuum breaker. Inspect mating threads and sealing surfaces before assembly to avoid leaks. Do not overtighten brass fittings, as this can crack or distort the component.
