Magnetic Self-Close Floor Drain Backflow Preventer, Anti-Odor Shower Strainer 1/2/3 Pack

Drain odour is almost always a backflow problem — sewer gases rising through a dry or poorly sealed drain trap. A magnetic self-closing insert solves it at the source, without chemicals, without plumbing work, and without replacing the drain.

The magnetic closure holds the insert shut when water isn't flowing, blocking sewer gases from rising through the drain. When water flows, the pressure opens the insert automatically and closes it again when the flow stops. It fits inside the existing drain without tools or adhesive.

• Magnetic self-closing mechanism — holds the insert shut when water isn't flowing, blocking sewer gases; opens automatically under water pressure and closes again when flow stops.
• Anti-odour backflow prevention — eliminates drain odour caused by sewer gas backflow without chemicals, plumbing work, or drain replacement.
• Tool-free installation — drops into the existing drain opening without adhesive or tools; fits standard floor drain sizes.
• Hair and debris strainer — the insert catches hair and debris before they reach the pipe, combining odour prevention with clog prevention in one component.
• 1, 2, or 3 pack — order the quantity needed for multiple drains in a single purchase.

The fix for drain odour that doesn't require a plumber. Drop it in, and the problem is solved.
