Vented Loops

Vented loops are essential for preventing backflow and siphoning in marine plumbing systems. They allow air to enter lines like bilge pump discharge or toilet flush hoses, ensuring safe and reliable operation. Built from corrosion-resistant materials, they’re a must-have for onboard safety. Install them above the waterline for maximum effectiveness.
