The Green Drain can be used in the outlet connections of floor drain bodies or the inside of the floor drain strainers to seal the opening, preventing odors, sewer gases, and insects from entering up through the floor drain grate. The Green Drain's four flexible silicone sealing ribs ensure easy installation into openings that have variations in size. The Green Drain will open to allow drainage and close when there is no water flow. It can be used in new construction or retro-fit applications where trap primers were never installed. It is a simple alternative to a trap primer with no mechanical parts to replace or maintain.
