Which description best fits Dual Check Backflows (ASSE 1024)?

The classification of Dual Check Backflows as a device for residential applications is accurate because these devices are specifically designed to prevent backflow in situations that are typically found within residential plumbing systems. Dual Check Backflows utilize two check valves to create a barrier against the back siphonage of contaminated water into the potable water supply. This makes them particularly suitable for residential settings where the health hazard from backflow is typically classified as low to moderate.

Additionally, while other types of backflow prevention devices are indeed used in various applications, Dual Check devices are not adequate for high health hazard scenarios, nor are they limited to commercial or agricultural use. Rather, their design and function make them ideal for individual residences, where they help ensure that the water supply remains safe from potential contaminants. This context reinforces their primary role in protecting residential water systems from backflow without delving into higher hazard applications.
