Why Choose This Drain Seal?

Unlike simple rubber plugs, this valve uses a one-way check mechanism that allows water to drain freely while forming a tight seal against backflow and sewer gases when the drain is idle. The anti-aging rubber resists deformation even after years of use, making it a smart, long-lasting solution for any home bathroom renovation project.

Frequently Asked Questions

Q: What pipe sizes does this floor drain seal valve fit?

A: This drain seal valve is available in three common sizes — 50mm, 75mm, and 110mm — making it compatible with the vast majority of standard bathroom and kitchen floor drain pipes. The flexible elastic rubber ring ensures a tight, secure fit within the pipe.

Q: Do I need any tools or professional help to install this drain seal?

A: No tools are required. Simply insert the rubber gasket core directly into your existing drain pipe opening. It sits securely in place thanks to the elastic sealing ring. It's also easy to remove for periodic cleaning or replacement.

Q: How does this valve prevent sewer odors from entering the bathroom?

A: The built-in one-way check structure acts as a mechanical barrier — it opens under the weight of draining water and closes automatically when the drain is idle, sealing off sewer gases and preventing wastewater from flowing back up into the room.

Q: Is this seal valve durable enough for long-term use in wet environments?

A: Yes. The valve is constructed from corrosion-resistant metal combined with high-quality rubber that resists aging and deformation. It is specifically designed to handle continuous exposure to water and wastewater without rusting or deteriorating over time.
