360-degree drainage: Transitions from gravity drainage to centrifugal drainage for full 360-degree water flow, enabling fast and efficient drainage. Resists clogging and prevents standing water at the bottom. Simply insert the deodorizing floor drain core into the sewer pipe for quick installation in seconds. The updated design has been rigorously tested to help maintain a clean and odor-free bathroom environment. Automatic drainage switch: Features a patented magnetic levitation mechanism that automatically opens during water discharge to ensure smooth flow, then seals tightly after drainage to block sewer gases and prevent odors from entering the room. Helps prevent backflow and potential water leaks. Durable and convenient: The drain core installs quickly by inserting it into the drain. When cleaning is required, the handle allows for easy removal of the filter element. Constructed from high-quality brass and advanced PPS nano material for long-lasting durability and stability. Clean and hygienic: Built-up debris in plumbing can harbor bacteria, generate gases, and attract pests, posing health risks. This floor drain features a joint and vortex anti-backflow design that effectively blocks gas release and intrusion of small organisms. The rotating structure includes a self-cleaning function to help keep the drain clear and hygienic. Compatibility: Designed to fit most drain openings with a diameter of 3.8 to 4.5 cm and a depth of at least 8 cm. Compatible with approximately 99% of standard sewer outlets. Measuring your drain size and depth before purchase is recommended.
