About this file
This is an inventory list of backflow prevention devices (RPZ and DCVA units) inspected across multiple buildings on May 1, 2023. The document provides a comprehensive catalog of 69 devices distributed throughout facilities numbered 1 through 88, with additional designations for specialty areas such as PTSD, Building T-44, T-58, T-59, T-60, and others.
The inventory includes devices manufactured primarily by Watts, with supplementary units from Zurn Wilkins, Ames, and Colt. Device sizes range from 3/4 inches to 6 inches, with the majority being Reduced Pressure Zone (RPZ) assemblies and Double Check Valve Assemblies (DCVA). Notable locations include mechanical rooms, basements, boiler rooms, penthouses, and specialized areas such as cart washers, crawl spaces, and pump rooms. Most devices are rated at 250 or 350 pressure ratings, with some rated at FS 500 or FS 600. Serial numbers and model designations are documented for each unit, though some entries note illegible or missing information. All devices were inspected on the same date (5/1/2023), suggesting a comprehensive facility-wide testing and certification campaign for backflow prevention compliance.
