25mm Dual Check Valve - Female/Female

Required back-flow protection | Female BSP threads both ends | AS/NZS compliant

The 25 mm Dual Check Valve is an essential component for irrigation and potable-water systems where back-flow prevention is required. With female BSP threads on both ends, this valve offers a straightforward inline installation between your water supply and your irrigation system or connection point. Dual independent check mechanisms mean the valve guards against both back-pressure and back-siphonage, helping protect the potable water supply from contamination. 

Ideal for:

• Mains water feed into irrigation systems
• Rain-water tank connections or first-flush systems
• Domestic meter connections where low-hazard back-flow protection is required
• Residential and light commercial irrigation installations

Key Features:
✅ Female 25 mm BSP threads on both inlet and outlet for easy inline replacement. 
✅ Certified to AS/NZS 2845.1 for low-hazard water supply protection. 
✅ Durable brass/bronze body construction for long-term outdoor performance.
