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.

The Green Drain is an environmentally friendly water-free trap seal designed to prevent sewer gases, odors, and pests from entering buildings through floor drains. It uses a flexible silicone membrane that allows water to flow through while sealing off when water flow stops.
The device has a silicone membrane that opens to let water and debris pass through and closes to prevent the backflow of gases and pests once the water stops flowing.
The Green Drain’s design allows water to rinse the membrane, preventing the buildup of dirt, hair, and grease that is common in traditional trap seals.
It can be installed in almost all types of floor drains in various settings, including factories, schools, hospitals, restaurants, hotels, public buildings, and residential homes. It is suitable for new buildings and retrofits in older structures.
Yes, it can be installed without tools. After removing the drain grating, the Green Drain can be pushed into the pipe to fit snugly. For optimal flow, it is recommended to recess the Green Drain 2-3 inches into the drainpipe.
Yes, it can be installed in shower drains by recessing the unit 4-6 inches into the pipe. It can also be installed in bathtub drains, but it is not recommended to replace traditional drain plugs with the Green Drain.
