360-degree drainage: Transforms gravity drainage into centrifugal drainage for full 360-degree water flow, enabling fast drainage, reduced clogging, 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 thoroughly 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: Install by inserting the core into the drain—no tools required. When cleaning is needed, simply pull out the core 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: Built-up debris in pipes can harbor bacteria, generate gases, and attract insects, compromising indoor hygiene. This floor drain features a joint and vortex anti-backflow design that helps prevent gas leakage and intrusion of small organisms. The rotating structure enables a self-cleaning action, keeping the drain clean and hygienic over time. Compatibility: Designed to fit most standard drain openings with diameters between 3.8 cm and 4.5 cm and a depth of at least 8 cm. Compatible with approximately 99% of common sewer outlets. Measure your existing drain size and depth before purchasing. The included silicone drain hose extensions are suitable for use in kitchens, bathrooms, and laundry rooms.
