FEATURES AND BENEFITS
– Ensures water cannot siphon over plumbing loops.
– Internal valve avoids need for external venting
– Molded in tough, corrosion-proof plastic
– Available in three sizes for 1 1/2″ (38mm), 1″ (25mm) and 3/4″ (19mm) hose.

A vented loop is a one-way valve used in marine plumbing systems to prevent siphoning and backflow of fluids, such as seawater or wastewater. It is commonly installed in marine toilets, bilge pumps, and engine cooling systems to maintain proper system function and prevent water from unintentionally flowing backward. The loop includes a small air vent at its highest point, which breaks the siphon effect when the system is not actively pumping. This prevents flooding, contamination, and unintended water ingress, making it a crucial component for safe and efficient onboard plumbing
