【Magnetic】The floor drain core uses magnetic suction technology, which opens the water outlet when the water flow passes and closes the opening when there is no flow 【Large water flow】The gravity force of the water flow is converted into centrifugal force to accelerate the flow, no matter how big the water is, it is not easy to block, and the flow is magnetically closed to close quickly. 【Keep clean】Our floor drain uses a sealing ring and a swirl anti-backflow design, which can effectively prevent the spread of odor and the outflow of foreign matter. 【Wide application】The floor drain core can be used for 39-45mm drains, plug-and-play, bathroom, balcony, kitchen, basement, laundry room, garage and other places.
