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 magnetic levitation mechanism that automatically opens during water discharge to ensure smooth flow, then seals shut after drainage to block sewer odors and prevent backflow. Helps prevent water leaks and stops odors from entering living spaces. Durable and convenient: The drain core installs easily by inserting it into the drain. When cleaning is needed, simply pull out the core using the built-in handle. Constructed from high-quality brass and advanced PPS nano material for long-lasting performance and stability.
