Green Drain GD3 Waterless Drain Trap Seal - 3''

The Green Drain helps keep your drains sealed and safe. Simply put, you place it inside your floor drains. It acts like a gate: keeping bad smells, sewer gases, and bugs from coming up while still letting water flow down. It’s easy to install thanks to its flexible silicone sides and works in drains of slightly different sizes. The Green Drain opens when water needs to go down and closes when it doesn’t, ensuring nothing can come up through idle drains. Plus, it’s great for any building, whether new or old, even where certain plumbing features, like trap primers, weren’t installed originally.
