Albin Group Marine Vented Loop 19

The Albin Group Marine Vented Loop 19 is a 19mm (3/4″) air valve assembly engineered specifically for marine waste water system safety. Designed for vessel operators and marine technicians who work with below-waterline sanitation systems, this component serves as a critical safety requirement to prevent dangerous back-siphoning conditions. Whether you're outfitting a new vessel or upgrading existing plumbing infrastructure, this vented loop meets international marine standards and delivers the compliance and peace of mind demanded in professional maritime applications.

The vented loop operates by breaking the siphon action that can occur in below-waterline waste systems, using a simple yet effective air valve design to allow atmospheric pressure to interrupt negative pressure cycles. Manufactured to CE marking 94/25/ECC and ISO 8846 Small Craft standards, the Albin Group Marine Vented Loop 19 delivers certified durability and reliability in salt-water and freshwater environments. The compact 3 x 1 x 4 inch profile and minimal 0.1 lb weight make installation straightforward without adding unnecessary bulk to marine plumbing layouts, while the 19mm port diameter ensures compatible integration with standard marine waste system tubing and fittings.

This component is essential for any vessel with a head system positioned below the waterline, from commercial fishing vessels and patrol craft to recreational sailboats and motor yachts. Proper installation of a certified vented loop prevents raw sewage backup into cabin spaces and protects crew health and vessel integrity. Installation requires placement in the waste line between the toilet and holding tank, positioned above the vessel's waterline to ensure the valve can function effectively and comply with USCG, EU, and international maritime regulations.
