What is the GREEN DRAIN™? 

The GREEN DRAIN™ is an environmentally friendly water free trap seal, which can be installed in basically all floor drains without the use of tools.

Why is GREEN DRAIN™ self-cleaning? 

GREEN DRAIN™ allows water to rinse the membrane and has no “labyrinth” opposite to normal trap seals that collects dirt, hair, and grease.

Where can I install GREEN DRAIN™?

GREEN DRAIN™ can be installed in almost all types of floor drains. In new buildings as well as older buildings. Private houses as well as industrial use with only minimal limitation.

Examples of common places: Factories, Schools/Universities, Arenas/Sports Venues, Office Buildings, Hospitals, Restaurants, Hotels, Food Production Factories, Ships, RV’s, Public Buildings etc.

Which sizes do GREEN DRAIN™ come in?

GREEN DRAIN™ is available in 6 different sizes, which are flexible and cover different measurements as shown below. GREEN DRAIN™ fits in almost all floor drains with diameters according to following intervals:

Model Size

  • GD15 (1.5”): 36-47 mm
  • GD2 (2”): 50-58 mm
  • GD3 (3”): 75-85 mm
  • GD35 (35”): 89-100 mm
  • GD4 (4”): 102-110 mm
  • GD5 (5”): 120-135 mm

  • Test House: Tokyo Metropolitan Industrial Technology Research Institute

Is GREEN DRAIN™ easy to install?

GREEN DRAIN can be installed without the use of tools after the grating has been removed. Just push the GREEN DRAIN into the pipe and make sure it fits snug. For maximum flow of liquids passing down the drain, simply recess Green Drain 2-4 inches within the drainpipe.

Can I install GREEN DRAIN™ in a shower drain?

Yes, GREEN DRAIN™ can be installed in a shower drain. We recommend recessing the unit 4-6 inches into the physical pipe rather than the drain hub or housing. Recessing the unit assists with greater flow of liquids passing down the drain.

Can I install GREEN DRAIN™ into a bathtub drain?

Technically YES, however, most bathtubs are manufactured with a drain plug that allows the user to control the drainage. We do not recommend replacing the drain plug with a Green Drain™.

How does GREEN DRAIN™ work?

GREEN DRAIN™ has a flexible silicone membrane (1-way valve) which allows liquids to pass freely through, and instantly closes and seals once liquids stop flowing.

Why choose GREEN DRAIN™?

GREEN DRAIN is the most simplistic remedy for mitigating unwanted sewer odors, sewer gases, pests, and aerosolized pathogens/bacteria, without the use of traditional caustic and harmful chemical applications. A truly Eco-Friendly solution for drain maintenance.

Does GREEN DRAIN™ replace a traditional water trap seal?

GREEN DRAIN™ replaces a traditional trap seal contributing numerous advantages:

  • Improves indoor air quality due to no sewer smell and gases.
  • Prevents wastewater penetration/backflow.
  • Self-cleaning and does not block the water flow.
  • No dry water seals and resists vacuum in the drainage system.
  • Decreases evaporation time within existing traps.

Can GREEN DRAIN™ be installed where traditional Traps are not present? 

Yes, please revert to your local plumbing codes for acceptability.

Can GREEN DRAIN™ be installed horizontally and vertically? 

GREEN DRAIN contains no liquids, and functions perfectly both horizontally and vertically.

What materials are used to produce GREEN DRAIN™?

GREEN DRAIN™ consists of UV resistant ABS housing, a silicone rubber sealant/membrane (1-way valve), and four flexible sealing flanges for easy installation and perfect fit.

Can I install a GREEN DRAIN if I have a P-trap in the ground?

Yes, GREEN DRAIN™ is NOT a traditional water trap and does not contain liquids.

GREEN DRAIN™ can be used in conjunction with Trap Primers or installed where Trap Primers are nonexistent. Check with your local jurisdiction for approvals to use GREEN DRAIN™ in lieu of water-fed Trap Primers.

Is GREEN DRAIN™ categorized as a Backflow Device?

No, GREEN DRAIN™ is not a backflow device, however, it can withstand up to 4 lbs. of pressure before the silicone valve inverts. Plumbing regulations for Trap Seal Devices require the silicone valve to essentially fail or invert if the pressure within the pipe is greater than 4 lbs.

GREEN DRAIN™ provides a barrier of protection between the sewer and the application site. Used in the outlet connections of floor drain bodies, or the inside of floor drain strainers to seal the opening to prevent 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. This Inline Drain Trap can be used in either new construction or retrofit applications where trap primers were never installed.
