The ASSE 1022-approved vented dual check backflow preventer is designed to protect both plumbing and drinking water from contamination, ensuring system safety and integrity. It offers reliable defense against the corrosive effects of CO2 gas, which can otherwise damage the system.
The primary check valve serves as the first line of defense against back pressure from the CO2-water mixture created during the carbonator's pumping cycle. If fouling or leakage occurs, the system safely vents the mixture through a specialized fitting, preventing any backflow into the clean water supply.
Additionally, the secondary check valve provides extra protection, ensuring that the CO2-water mixture cannot reach the inlet or encounter brass/copper components. This dual-layered protection is essential for preventing corrosion and minimizing the risk of system failures due to chemical reactions.
Simplicity and Ease of Maintenance
The backflow preventer features a simple internal design, making maintenance tasks like inspections, cleaning, and testing more efficient. Regular upkeep ensures optimal performance and reduces the risk of contamination or corrosion.
Made from lead-free brass and stainless steel, the ASSE 1022 prioritizes safety and durability, preventing corrosion and protecting the water supply from harmful contaminants like lead. Its design keeps the CO2 mixture separate from the plumbing system, maintaining safety standards.
The ASSE 1022 vented dual check backflow preventer is key to protecting plumbing from CO2’s corrosive effects. With its reliable design and materials, along with regular maintenance and Anderson Brass support, users can ensure ongoing system safety and efficiency.
