Seaflo Vented Loop 1-1/2" VL03

Essential Anti-Siphon Protection for Marine Plumbing

The Seaflo VL03 Vented Loop is a critical safety component for any marine vessel where plumbing systems are installed below the static or heeled waterline. Designed to facilitate the safe discharge of waste or water, this loop ensures that a siphon cannot form, preventing accidental flooding of the hull.

RELIABILITY: Engineered from high-strength, corrosion-proof plastic with an integrated one-way air valve, eliminating the need for external vent piping.

  • ✔ Internal Valve: One-way duckbill valve requires no maintenance.

Questions & Answers

Is this a genuine original part?

This is a premium quality Seaflo aftermarket replacement part, manufactured to meet or exceed original equipment standards for marine plumbing safety.

How do I know if it is compatible?

Measure the internal diameter of your discharge hose. This model VL03 is designed specifically for 1-1/2 inch (38mm) hoses, which is the standard size for most marine toilet discharge lines.

Does this require an external vent hose?

No, the Seaflo VL03 features an integrated internal duckbill air valve that automatically opens to break the siphon and remains closed during normal pumping, eliminating the need for an external vent line.

Note: Please verify your hose diameter and installation height requirements before purchasing. Visit 4boats.co.uk for more marine plumbing solutions.
