Whale 2-Way Waste Manifold - 12' Cable - 3/4" Ports2 Way Waste Manifold 12' Cable 3 4" Ports This manifold manages waste from multiple drains with intelligent control built in. A compact automatic system handles waste drainage from the two outlets. Must be used with Gulper IC. The two way manifold IC is connected to a Gulper IC. When the manifold senses water, it sends an electrical signal to the Gulper IC, which evacuates the system. As the water level decreases, the electrical signal transmitted by
