Product Details

The Seachoice 7591 Anti-Siphon Valve is a critical marine plumbing component designed to prevent backflow and siphoning in freshwater systems. This valve features a 1/4" NPT threaded inlet connection and a 3/8" hose barb outlet, making it ideal for installation in water lines to protect tanks, pumps, and plumbing systems from unwanted drainage.

Key Features:

  • Prevents siphoning and backflow in marine water systems
  • 1/4" NPT male threaded inlet connection
  • 3/8" hose barb outlet for secure hose attachment
  • Corrosion-resistant construction for marine environments
  • Compact design for easy installation in tight spaces
  • Essential for freshwater tank and pump protection

This anti-siphon valve is commonly installed above the waterline in freshwater systems to prevent water from draining back through the system when the pump is off. It's an essential component for boats, RVs, and marine applications where maintaining proper water system integrity is crucial.
