Are you most worried about drain odor, crawling insects, or even occasional backflow in rented homes or old houses? This FaSoLa floor drain core is specifically designed to solve these "invisible troubles." No need to hire a professional or break tiles; just insert it directly into your existing floor drain opening, and it will instantly block sewer odors and insects, while ensuring smooth drainage during showers.

It uses the principle of physical gravity to automatically open and close: it drains quickly when there is water, and closes tightly when there is no water. For shared bathrooms, dormitory showers, or vacant homes that haven't been lived in for a long time, this is the most cost-effective and fastest-acting hygiene protection solution.

• 【Plug-and-Play Design】No tools or modifications needed. Simply clean the old drain and insert it. Even women can easily install it, making it ideal for those who move frequently or don't want major renovations.
• 【Physical Gravity Seal】Automatically opens with water flow and closes automatically when dry, cutting off the source of odors and cockroach entry. Safer than chemical deodorizers.
• 【High Flow & Fast Drainage】Optimized internal structure ensures rapid drainage of accumulated water even during peak usage (e.g., multiple continuous showers), avoiding the embarrassment of stepping in dirty water.
• 【Corrosion-Resistant Material】Made of durable engineering plastic, it withstands humid bathroom environments and contact with cleaning agents, resisting deformation and aging with long-term use.

Usage Scenarios: Especially suitable for bathrooms and kitchens in old communities, rental properties, and student dormitories; also ideal for sealing drains to prevent indoor odors before long business trips or vacations.

Installation Tips: Before installation, be sure to clean any hair and dirt inside the drain opening to ensure the core can be inserted vertically and fit snugly at the bottom for the best sealing effect. Periodically remove and rinse the surface of the core to maintain long-term smoothness.
