Dual Check Valve – Low Hazard
Available Variants: 12mm to 50mm
The Dual Check Valve (Low Hazard) is designed to provide effective backflow prevention for low-risk applications in both residential and commercial plumbing systems. This valve helps prevent the reverse flow of potentially contaminated water, protecting potable water supplies from low-level hazards such as garden taps, domestic appliances, and other non-toxic sources.
Compact and easy to install, the dual check valve features two independently acting check mechanisms housed within a single body for added security and reliability. It is ideal for use where cross-contamination risks are minimal but backflow protection is still required under plumbing codes.

- Dual Check Protection: Two independently operating check valves for added safety
- Low Hazard Rating: Designed for use in systems where contamination risk is low
- Compact Design: Easily integrates into tight spaces in domestic and light commercial setups
- Durable Construction: Manufactured from high-quality, corrosion-resistant materials

- Australian Standards Compliant: Certified for potable water systems (AS/NZS 2845.1)
Typical Applications:
- Garden taps and hose connections
- Domestic dishwashers and washing machines
- Appliance connections in residential buildings
- Low-risk potable water applications in commercial settings
Choose the Dual Check Valve – Low Hazard to ensure your potable water system stays protected from unwanted backflow — with peace of mind and full compliance with Australian plumbing regulations.
