Description
The Watts 88004113 Reduced Pressure Zone Backflow Preventer Assembly is a necessary part for protecting HVAC systems from possible contamination. This Reduced Pressure Zone RPZ backflow preventer made from lead-free copper silicon alloy contains two check valves that close independently and a unique relief valve. Its major purpose is to avoid the water supply that is contaminated and supply the HVAC equipment with sewage or chemicals that could harm the system. This is especially an essential in condenser water systems such as cooling towers and chillers and or boilers where there is potential of contamination between systems.
