What Stands Out
Durable Brass Construction
Made from high-quality brass, this dual check valve ensures long-lasting durability and resistance to corrosion, making it ideal for reliable backflow prevention in various plumbing applications.
Intermediate Atmospheric Vent
The unique atmospheric vent offers additional safety by allowing trapped air to escape, preventing backflow and ensuring optimal performance in preventing contaminated water from entering clean supply lines.
Easy Installation
Designed with female union inlet and outlet connections, this backflow preventer allows for quick and straightforward installation, making it a hassle-free solution for both professionals and DIY enthusiasts.
