Anti-Odor Floor Drain Plug – One-Way Valve Shower Stopper
Anti-Odor Floor Drain Plug – One-Way Valve Shower Stopper
Keep Odors, Insects & Backflow Out of Your Bathroom
This smart one-way valve floor drain stopper is the easy, hassle-free upgrade your bathroom, kitchen, or laundry room needs. Using a simple gravity-powered mechanism, the ABS plastic gasket opens automatically when water flows in, then seals itself shut the moment draining stops — creating a complete barrier against sewer gases, insects, and unwanted backflow.
How It Works
- Gravity-Activated Opening: Water weight pushes the internal ABS gasket open for fast, unimpeded drainage.
- Automatic Self-Sealing: Once water flow stops, the gasket closes under its own weight — no springs, no levers, no maintenance.
- Complete Pipeline Seal: Keeps sewer gases, pests, and backflow sealed below the drain at all times.
