Inspect the seal around 6 to 12 months in service to confirm the silicone is still intact and sealing properly. Replace only as needed: high-use drains wear sooner, while low-use drains often last a year or longer.

How it works.

Green Drain is a one-way valve for your floor drain. Water flows down and out. Nothing comes back up.

Inside sits a soft silicone valve. Running water pushes it open; the moment the water stops, it closes and seals tight against sewer gas, odors, and pests. Because it seals with silicone instead of water, it never dries out the way an ordinary trap can, even when the drain goes weeks without use.

It fits 6-inch drains, 149 to 157 mm, and drops in by hand. No tools, no plumber, installed in seconds.

Installs in under 60 seconds. No tools.

Step 1: the grate lifted off a floor drain, shown in section

Lift the grate

Most grates lift straight out by hand. Some are held by one center screw; back it out, then lift.

Step 2: measuring the pipe opening at the bottom of the drain, inside wall to inside wall

Measure the opening

Measure the pipe opening at the bottom of the bowl, inside wall to inside wall. The GD6 fits 149 to 157 mm (6 in.).

Step 3: the GD6 being pressed down into the pipe opening

Press gently to seat

Recess 2 to 4 inches below the pipe top. The silicone gasket creates a snug seal against the pipe walls.

Step 4: the grate back in place over the seated GD6

Replace the grate

Put the grate back. Done. Full coverage for your largest drains.
