Back-flow Devices

Back-flow Devices

Backflow prevention devices are engineered safety assemblies designed to prevent the reverse flow of contaminated water into potable water supply systems. Commonly required by plumbing codes and health regulations, these devices protect drinking water systems in residential, commercial, industrial, and municipal applications from contamination caused by backpressure or back-siphonage conditions. This category includes double check valve assemblies (DCVA), reduced pressure zone (RPZ) assemblies, atmospheric vacuum breakers (AVB), pressure vacuum breakers (PVB), double check detector assemblies (DCDA), and specialty backflow prevention devices used in irrigation systems, fire protection systems, commercial plumbing, and water service applications.
