Backflow Preventer Assemblies

This federal solicitation (M0068126Q0096), issued by the Commanding General of Marine Corps Base Camp Pendleton on behalf of the Marine Corps Air Station (MCAS) Yuma, is a 100% small business set-aside. Under NAICS code 332911 (Size Standard 750), the Marine Corps is seeking quotes for a single, firm-fixed-price purchase order to procure backflow preventer assemblies. The primary objective of this contract is to replace existing backflow preventers for the MCAS Yuma Installation, Logistics, and Environmental Department to ensure compliance with Arizona Department of Environmental Quality (ADEQ) cross-connection-control and backflow-prevention regulations. Quoted items must be brand name or equal to those specified in Exhibit A, meeting all minimum salient characteristics. Quotes must be submitted electronically to Sgt Sabastian Lake and SSgt Allen Hayes no later than 11:00 AM PDT on September 21, 2026. The contract delivery period requires shipment to the MCAS Yuma Distribution Management Office on or before November 29, 2026. Evaluations will be conducted using simplified acquisition procedures based on two primary factors: Technical Acceptability (rated as Acceptable or Unacceptable) and Price. To be deemed technically acceptable, vendors must submit a completed Specification Sheet, a Country of Origin statement, and an affirmative delivery schedule. Active registration in the System for Award Management (SAM) is required at the time of submission and award.

This document is a collection of technical specification sheets and product submittals for backflow prevention assemblies from manufacturers including Zurn Wilkins, Watts, Febco, and Apollo Valves. These materials are typically compiled for government RFPs, municipal public works projects, and state or local water utility grants to verify equipment compliance with engineering standards and lead-free regulations. The submittals detail various Reduced Pressure Principle Assemblies (RPZ), Double Check Valve Assemblies, and Pressure Vacuum Breakers. Key models featured include the Zurn Wilkins 375XL and 975XL, the Apollo RP4A series, the Febco 825Y and 765-QT-PVB, and the Watts Series 909 and LF709. These devices are designed for potable water lines to protect municipal water systems against backsiphonage and backpressure of contaminated fluids under high-hazard conditions. The specifications highlight compliance with rigorous industry standards, including ASSE 1013/1015, AWWA C511/C510, CSA B64.4/B64.5, and approval by the Foundation for Cross-Connection Control and Hydraulic Research at the University of Southern California (USC FCCCHR). Additionally, the assemblies meet NSF/ANSI/CAN 61 and 372 requirements for lead-free plumbing, utilizing materials like cast bronze, stainless steel, and FDA-approved elastomers. The document provides crucial dimensional data, weights, optional configurations (such as strainers, air gaps, and union ball valves), and performance flow curves to assist government procurement officers and engineers in selecting compliant infrastructure hardware.

This technical specification document outlines the Watts Series LF009 Reduced Pressure Zone Assemblies, which are designed to protect potable water supplies from backflow due to backsiphonage or backpressure. Suitable for health hazard cross-connections, containment at service line entrances, irrigation, and boiler feeds, these assemblies meet major national plumbing codes and standards, including ASSE 1013, AWWA C511, and CSA B64.4. The assemblies feature a Lead Free construction to comply with lead-free installation requirements, containing less than 0.25% lead by weight. Sizes ranging from 1/4" to 2" utilize a cast copper silicon alloy body, while 2-1/2" to 3" sizes feature a fused, epoxy-coated cast iron unibody with ArmorTek technology to resist microbial-induced and electrochemical corrosion. A key feature for sizes 1/2" to 3" is an integrated, exterior-mounted flood sensor that detects excessive relief valve water discharge. When activated via an add-on connection kit, the sensor transmits alerts through building management systems (BMS) or cellular networks to mitigate flooding risks. The modular design includes two independent check valves, captured springs, replaceable seats, and an internal relief valve, allowing for simplified, top-entry maintenance without special tools. Rated for supply pressures up to 175 psi, the assemblies support water temperatures up to 180°F for smaller sizes, and up to 140°F intermittent for larger sizes.

This technical specification sheet details the Watts Series 957 Reduced Pressure Zone Assembly, a backflow preventer designed to protect potable water systems from contamination due to backsiphonage or backpressure. Commonly utilized in health hazard applications, this assembly features a compact, lightweight design with a 304 stainless steel housing, replaceable check disc rubber, and patented torsion spring checks that minimize pressure loss. A key feature of the Series 957 is an integrated flood sensor on the relief valve. When paired with an optional add-on connection kit, the sensor transmits alerts via Building Management Systems (BMS) or cellular networks to notify personnel of excessive water discharges, helping prevent costly flood damage. The document outlines various configurations and options, including non-rising stem (NRS) gate valves, outside stem and yoke (OSY) gate valves, and grooved gear-operated butterfly valves (BFG). It lists approved standards—such as the Foundation for Cross-Connection Control and Hydraulic Research (FCCCHR-USC)—and details materials, pressure-temperature ratings (maximum 175 psi and 33°F - 140°F), physical dimensions, weights, and flow capacity curves across sizes ranging from 2½" to 10". This product specification is critical for engineers and contractors preparing compliance submittals for public water infrastructure, facility maintenance, and government utility projects.

This document outlines the minimum salient characteristics required by the Marine Corps Air Station, Installation, Logistics and Environmental Department for replacement backflow-prevention assemblies. The procurement is necessary to comply with the Arizona Department of Environmental Quality (ADEQ) cross-connection-control and backflow-prevention requirements under Arizona Administrative Code R18-4-215. The selected contractor must provide assemblies that satisfy specific regulatory standards, material requirements, and safety protection levels. These protection levels include Reduced Pressure Principle (RP) assemblies for health hazard areas, Pressure Vacuum Breaker (PVB) assemblies for certain irrigation systems, and Double Check Valve (DC) assemblies where permitted. Additionally, the assemblies must be constructed of corrosion-resistant, potable-water-safe materials suitable for outdoor use. They must also be sized to seamlessly match the facility's existing piping configurations and potable-water distribution system without requiring unplanned modifications. Compatible models and dimensions are specified for various pipe sizes ranging from 1/2” to 6” from manufacturers such as Zurn-Wilkins, Apollo, FEBCO, and Watts.

This document is a technical specifications and quantity list for backflow preventers, likely compiled for a government procurement or public works utility contract (marked for "DoW Community Only" distribution). It details the required size, manufacturer model, dimensions, quantity, and pricing category for 52 backflow assembly units. The list features equipment from major manufacturers, including Wilkins, Apollo, Febco, and Watts, with sizes ranging from 1/2 inch to 6 inches. Major components specified include 375XLRP and 975XLRP Wilkins assemblies, Watts 009RP and 957RP units, and Febco models. Quantity requirements vary by model, with 2-inch units (specifically the 2" 375XLRP Wilkins) representing the largest individual line item at 9 units. The document serves as a standardized inventory and sizing sheet to facilitate accurate pricing and procurement of water distribution system safety devices.
