Dual Check Valve Backflow Preventer For High-Flow Applications
Versatile, high-performance dual check backflow preventers
VersaCheck® Dual Check Valve Backflow Preventers are independently certified by QAI Laboratories to meet ASSE 1024, NSF 61, and NSF 372. The VersaCheck line provides reliable, cost-effective protection for the public water supply and can be used on all potable water lines. All models provide both backsiphonage and backpressure protection when installed according to manufacturer’s directions and state and local plumbing requirements.
While most backflow preventers come in rigid sizing and connection types, VersaCheck utilizes a common female NPT inlet and outlet in order to maximize flexibility and ease of installation. Whether the install calls for flexible tubing or rigid pipe, VersaCheck can be adapted to fit any installation with adapters available from the local hardware store.
Keeping water supplies safe is paramount, so the entire VersaCheck lineup utilizes drinking-water-safe PVC or the industry-first hardcoat anodized aluminum. Whichever material you choose, the VersaCheck backflow preventer delivers high performance while meeting the strict standards required by ASSE and NSF.
- 100% lead-free construction
- Female NPT (FNPT) inlets and outlets provide maximum flexibility
- Non-corrosive, non-reactive materials
- Low pressure drop with high flow rates
