This 2-1/2" stainless steel reduced pressure zone assembly backflow preventer helps prevent the reverse flow of contaminated water from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements.
