Durable Material: The shower sink strainer is made of high quality ABS material, which is sturdy and not easily damaged for long term use. Magnetic Seal: Our floor drain uses magnetic levitation technology, which uses the principle that magnets repel each other to seal when there is no water flowing out, which can prevent odors and bedbugs and prevent sewage from overflowing. When the water is drained, the pressure of the water flow opens the sealing opening and quickly closes it after the water is drained. Good sealing effect. Large water drainage: The gravity of the water flow is converted into centrifugal force to accelerate drainage, no matter how big the water is, it can be drained quickly without clogging, and the drainage is magnetically completed to close quickly, with good anti-odor effect. Easy to use: The floor drain is a practical deep seal deodorizing floor drain core, plug and play type. Suitable for pipes with a diameter of 40mm without rim and a floor drain depth of more than 50mm, ready to use once inserted. Multi-purpose use: deodorizing sealing gasket; damping ring to prevent sewer backflow. Simply install it in any floor drains, such as basements, laundry rooms, bathrooms, kitchens, garages, etc., to provide you with clean air and a pleasant life!
