Four flexible silicone sealing ribs form a one-way valve. Water and debris pass through freely under gravity. When flow stops, the ribs close and create a continuous mechanical seal, blocking sewer gas, odors, and pests from traveling back up through the drain.
The device drops into the drain outlet or hub with no tools and no plumbing modification.
