FEBCO

The FEBCO 825YA series is a line of reduced pressure zone (RPZ) backflow preventers designed to protect potable water supplies from cross-connection contamination. These assemblies are installed in commercial and industrial plumbing systems where a high hazard of backflow exists. The 825YA models are available with FNPT or flanged connections, and some include a flood detection sensor and strainer. They are typically used in applications such as irrigation systems, fire protection systems, and process water lines. The RPZ design provides a high level of protection by maintaining a pressure differential between the supply and the zone, with relief valve discharge if a fault occurs.

3G Electric supplies FEBCO backflow preventers in sizes including 3/4 in, 1 in, 1-1/4 in, 1-1/2 in, and 2 in. The current catalog includes models such as the 3/4 LF825YAQTRPFS and 1 825YA-QT-RP-FS, as well as repair kits for 3/4 in to 1-1/4 in and 1-1/2 in to 2 in assemblies. Larger sizes may be available upon request. The product listings include specifications for connection type, shut-off valve type, and included features such as flood sensors and strainers. For specific size and configuration requirements, buyers can reference the part numbers and compatibility details provided.

FEBCO repair kits for 825Y and 825YA series backflow preventers contain specific components needed to service the assembly. Examples include the rubber parts kit (SKU 905111) which includes covers, the single check kit (SKU 905044) with a cover O-ring, the relief valve repair kit (SKU 905054) with two O-rings, the rubber parts kit (SKU 905112) with two seat O-rings, and the relief valve repair kit (SKU 905045) with a diaphragm. These kits are compatible with valve sizes from 3/4 in to 2 in, depending on the kit. They are used to replace worn rubber components, seals, and diaphragms during routine maintenance or repair of backflow prevention assemblies.

FEBCO produces both reduced pressure zone (RPZ) valves and double check valve assemblies. An RPZ valve, such as the 825YA series, provides a higher level of protection by including a relief valve that discharges water if the pressure differential between the two check valves is compromised. This makes RPZ valves suitable for high-hazard applications. A double check valve assembly consists of two check valves without a relief valve, and is used for low-hazard applications where backflow is not considered a health risk. The selection between the two depends on the degree of hazard and local plumbing codes. FEBCO's catalog includes RPZ models and repair kits for both types.

Some FEBCO backflow preventers, such as the LF825YA model (MPN 3/4 LF825YAQTRPFS), are available with an integrated flood detection sensor. This sensor is designed to detect water discharge from the relief valve, which can indicate a fault in the assembly. The sensor can be connected to a building management system or alarm panel to provide early notification of a potential issue. This feature is useful in applications where undetected water discharge could cause property damage or where remote monitoring is required. The flood detection sensor is included on specific models and is not present on all FEBCO backflow preventers.
