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.
The Green Drain comes in eight sizes to fit different drain diameters:
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.
Yes, it replaces traditional water trap seals and offers several advantages, including improved indoor air quality, prevention of wastewater backflow, and resistance to vacuum in the drainage system.

Fast arrival (including to Canada), easy to install, seems to have done the trick!
We have replaced the traditional water trap seals with GREEN DRAIN’s membrane trap seal, and this installation has eliminated all problems with odours coming from the floor drains. Being the largest airport in the Nordic Countries, hosting approximately 100,000 travelers daily, it is very important that our drains remain maintenance free, in order to always ensure a satisfactory customer experience.
GREEN DRAIN has really shown its worth in especially two places. Firstly, in the toilet facilities, where drain traps quickly evaporated due to the low amounts of water used in the new eco-friendly way of floor cleaning, compared to earlier methods. Secondly, in the ventilation rooms where vacuum also caused unpleasant smells from the sewer system. Both places GREEN DRAIN solved the problems easily.
We have already installed the Green Drain with many of our customers. The use of Green Drain is of great satisfaction. Not only in floor drains but also in the air ventilation systems. Green Drain is the perfect solution to prevent penetration of insects and vermin from the drains.
2½ years ago we installed GREEN DRAIN in our hotel rooms and in our swim center, which has generated man-hour savings in the daily cleaning routines. Previously we had to make sure that dirt wasn’t blocking the trap seal, that the trap hadn’t evaporated or wasn’t emptied by vacuum in the pipe system.
In the last 2½ years, we haven’t even touched GREEN DRAIN, which performs far better than we ever dreamt of. Now we don’t get unnecessary visits from guests in the reception regarding complaints about problems that GREEN DRAIN now prevents.
Dear Eddie
Thank you very much for coming out with Chemform and introducing us to the Green Drain. As a food manufacturer,
Mondo Doro is always looking to improve our food safety protocols and hygiene standards.
The Green Drain is an ideal device for our business, we feel secure in the knowledge that nothing that is in our drainage
system can come back out to potentially contaminate our produce. It is also a prevention device that is welcomed by
inspectors. The Green Drain solution is an essential tool for any food manufacturing plant, providing yet another level of
security against possible outbreaks. It is brilliant!
Easily installed and removed for cleaning in particular when we conduct deep sanitisation. The fact that it maintains an
airtight seal is a huge advantage. We will continue to install the Green Drain as part of our safety protocol in our future
projects. Happy to tell my colleagues and any other manufacturer about your winning solution.
Thanks again,
At Greengate, we pride ourselves on providing our residents with a boutique style of living and personal care. Our attention to detail and individual care is key to our services and client experience. At our Maroubra site – St. Brigid’s Green – our drain fly problem was becoming an issue for residents and staff alike, which I can safely say that it is behind us now.
Our fly infestation around our serving and dining areas seemed to be getting worse, spreading to a number of floors. Our hygiene company Medclean suggested we install Green Drains to seal their breeding grounds. We decided to attack the problem from all angles and combined a wholistic solution between our Pest Management and Hygiene and Green Drains.
Eddie initially came out to meet with our facility manager and conducted a site audit to evaluate our challenges. The service was very comprehensive and put together a complete drain maintenance solution plan to proactively protect our problem areas.
I can report that since the installation of Green Drains, we do not get any complaints or experience the challenges we once had, even though the warmer season is upon us. In some areas we could at times smell undesirable drain odours, this has also been addressed and without using harmful chemicals. Even our resident Chef loves it.
I would highly recommend the Green Drain to any age care facility wishing to be proactive in protecting their residents and staff from the potential health risks of unsealed drains.
Warmest regards,
“The Green Drain™ was very easy to install and has stopped all of the bad smells from coming up from the drain. We love it!”
