360-degree drainage: Transforms gravity drainage into centrifugal drainage for efficient 360-degree water flow, enabling fast drainage with reduced risk of clogs and no standing water at the bottom. Simply insert the deodorizing floor drain core into the sewer pipe for quick installation in seconds. The upgraded 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. Effectively prevents backflow, water leaks, and spills. Durable and convenient: Easy to install—just insert the drain core into the sewer. When cleaning is required, the filter can be easily pulled out using the built-in handle. Constructed from high-quality brass and advanced PPS nano material, the floor drain core offers long-lasting durability and stability. Clean and hygienic: Long-term accumulation of debris in pipes can lead to bacterial growth, unpleasant gases, and even insect infestations, posing health risks. This floor drain features a joint and vortex backflow design that helps prevent gas leakage and intrusion of small creatures. The rotating self-cleaning action helps keep the drain clean and hygienic over time. Compatibility: Designed to fit most drain holes with a diameter of 3.8 to 4.5 cm and a depth of at least 8 cm.
