TruDesign Vented Loops are composite siphon-break fittings designed for marine plumbing systems.
They help prevent water from siphoning back into a vessel. Common applications include toilet inlet and discharge systems, holding-tank discharge systems, generators, and small-engine cooling-water systems.
The integrated one-way breather valve allows air into the line when the system is not operating and seals when water or waste passes through the loop.
