This part, categorized as a lead free dual check valve backflow preventer and sized at 3/4″, has a double check function to ensure that the dangerous substances will not flow back. This backflow preventer is installed in the HVAC system and hence plays the role of a barrier whenever chillers or cooling towers are involved isolating the building’s potable water supply from the sources of contamination within the HVAC equipment. It reduces the likelihood of drawing contaminated water into the water supply and hence it better reduces on the possibilities of cross-contamination of the water supply for drinking.
