Stainless steel, copper and PVC are the main materials for floor drains. Copper drain pipes are popular for their beautiful appearance. However, all copper chrome is very expensive due to its intricate workmanship. Therefore, many people choose PVC rust-proof floor drain. The price is acceptable and the deodorizing effect is good, but it is fragile and not durable. At present, the main material is stainless steel, which is corrosion-resistant, durable and does not rust, and can be used for a long time. Plus, it's easy to clean. Generally, stainless steel floor drains can be used for at least 10 years.

In addition to the drainage function, deodorization is the key. We pay attention to design and materials when buying. A general floor drain includes a floor drain body and a floating cover. The floor drain body refers to the seal that stores water. Because the floor drain deodorization mainly relies on water sealing, the structure design is reasonable. The depth determines the sewage capacity and deodorant effect.

Now most of the leaks are shallow, only 1-2cm or less. The floor drain is sealed for several hours under positive and negative pressure. But winters are dry, so these "deodorant floor drains" lose their deodorizing effect in a short period of time. Only reaching a certain water depth (5 cm) is a truly qualified product, which can prevent odors, cockroaches and various mosquitoes from entering the room.
