Versatile, high-performance dual check backflow preventers

VersaCheck® Dual Check Valve Backflow Preventers are designed to provide reliable and cost-effective protection for public water supplies. Independently certified by QAI Laboratories to meet ASSE 1024, NSF 61, and NSF 372 standards, VersaCheck ensures the highest level of safety for all potable water lines. Whether used in residential, commercial, or industrial settings, these preventers safeguard against both backsiphonage and backpressure when installed according to manufacturer instructions and local plumbing codes.

Unlike many traditional backflow preventers that have fixed sizing and connection types, VersaCheck offers enhanced versatility with a common female NPT (National Pipe Thread) inlet and outlet. This design allows for easy adaptation to various installation types, whether you’re using flexible tubing or rigid pipes. The adaptability of VersaCheck means you can find the right fit for any installation with standard adapters available from your local hardware store.

Ensuring the safety of water supplies is of utmost importance, which is why the entire VersaCheck lineup is crafted from drinking-water-safe materials like PVC and industry-first hardcoat anodized aluminum. Both materials provide durable, high-performance solutions that meet or exceed the rigorous standards set by ASSE and NSF. With VersaCheck, you can trust in the quality and safety of your backflow prevention system.

By choosing VersaCheck, you are investing in a high-quality, lead-free backflow preventer that combines ease of installation with superior performance. Designed to handle various water supply conditions while maintaining low pressure drop and high flow rates, VersaCheck is the ultimate solution for backflow prevention.

  • 100% lead-free construction for safe and reliable water protection
  • Female NPT (FNPT) inlets and outlets for maximum installation flexibility
  • Non-corrosive, non-reactive materials ensure long-lasting performance
  • Low pressure drop with high flow rates for optimal water supply efficiency
  • Certified to meet ASSE 1024, NSF 61, and NSF 372 standards for quality assurance
