What is Green Drain™?

Patented one-way silicone seal that is installed in the body of an existing floor drain. Under the weight of water it opens downward, and at rest it remains hermetically sealed upward — physically blocking sewer gases, viral aerosols, and insects.

No water in the P-trap, no chemicals, no maintenance. Medical-grade silicone, proven long-lasting durability, SGS-tested to block >99.9 % of MS2 viral surrogates.

Questions about this size.

What customers ask about the GD-2.

GD-2 is for gullies with a 50–58 mm internal grate diameter. It's best to measure before ordering — our return policy covers incorrect sizes for 14 days.
No. The GD-2 passes 82.50 L/min — more than a normal load delivers at once. The seal opens downward under the weight of the water.
Wet cloth for regular floor cleaning. The seal remains in the drain; the grate is removed from above it. Visual inspection once a year.
Yes. Silicone is resistant to sodium hypochlorite up to 5 %, quaternary amines, isopropanol, and ethanol at standard food service and hospital concentrations.

GD 2″ fits a drain body with an internal diameter of 50–58 mm. If your measurement falls in that range, this is your size.
1
Lift the grate

Take out the existing grate or strainer. Underneath is the drain body — the pipe the seal drops into.

2
Measure the internal diameter

Measure the pipe opening, not the grate. The grate is always wider, and that is the single most common reason people order the wrong size.

3
Match it to a range

Find the size whose range your measurement falls into. If you are between two, take the smaller one — the silicone ribs expand.

No tape measure to hand? A strip of paper works: wrap it around the opening, mark where it overlaps, measure that length and divide by 3.14. And if you still get the size wrong, there is a 14-day return — send it back and we swap it, no questions.
