Backflow Device Types We Test

Fire Extinguisher Service Center tests all common device types found across Portland-area commercial, industrial, and residential properties.

Reduced Pressure Zone (RPZ) Assemblies

RPZ valves are required for high-hazard connections, including fire sprinkler systems using chemical additives and irrigation lines near fertilizers or pesticides. They are common on commercial properties in the Lloyd District and along the Highway 26 industrial corridor.

Pressure Vacuum Breakers (PVB)

PVBs protect low-to-moderate hazard connections such as residential irrigation systems. Many Beaverton and Tigard homeowners with in-ground sprinkler systems rely on PVBs as their primary protection device.

Double Check Valve Assemblies (DCVA)

DCVAs are typically used for moderate-hazard applications including multi-unit residential buildings and commercial cooling systems. Properties throughout East Portland and the Gateway District commonly use DCVAs on fire protection supply lines.

Each device type requires a different testing protocol and calibrated gauge verification. Our technicians carry the proper equipment for all three assembly types.
