Description
The Watts 0391010 LF RPZ Backflow Preventer Assembly is an essential part of HVAC systems that help protect the water supply from contamination. This RPZ assembly Uses two separate check valves and a reduced pressure chamber of a specific shape. When a backflow event happens like a drop in the downstream pressure, the first check valve shuts off the water supply. At the same time, the reduced pressure chamber is designed so that any back flow is contained within the part and the resulting discharge is safely directed to drain.
