Simply insert the deodorizing floor drain core into the sewer pipe for quick installation in seconds. The updated design has been thoroughly tested to help maintain a clean and odor-free bathroom environment. Automatic drainage switch: Features a patented magnetic levitation system that automatically opens during water discharge to ensure smooth flow and seals shut afterward to block sewer odors and prevent backflow. Helps prevent water leaks and stops wastewater from flowing back into the room. Durable and convenient: The drain core installs quickly by inserting it into the sewer. When cleaning is required, the handle allows for easy removal of the filter element. Constructed from high-quality brass and advanced PPS nano material, the floor drain core offers long-lasting durability and stability.
