Vetus ASDV Anti-Siphon Device with Valve for Marine Plumbing

The Vetus ASDV is a marine-grade anti-siphon device with an integrated duckbill valve designed to prevent back-flow in plumbing systems. This essential safety component protects against water siphoning that can occur when water lines are installed below the waterline, helping to prevent accidental flooding.

Key Features:

• Integrated duckbill valve for reliable one-way flow control
• Universal design fits multiple hose sizes: 13mm, 19mm, 25mm, and 32mm (1/2", 3/4", 1", and 1-1/4")
• Compact dimensions: 2.7" W x 3.8" D x 5.2" H for easy installation in tight spaces
• Durable construction suitable for freshwater and marine environments
• Prevents backflow and siphoning in toilet, sink, and shower drain systems

Commonly used in marine heads, galley sinks, and shower drain lines, this anti-siphon valve is an essential component for safe and reliable onboard plumbing systems. The device installs inline and must be mounted above the waterline to function properly.
