From the functional point of view, the floor drain is divided into two types: ordinary use and washing machine dedicated. The floor drain for washing machine has a round hole in the middle, which can be inserted into the drain pipe, and is covered with a rotatable cover. It can be covered when not in use and unscrewed when used. It is very convenient, but the anti-odor function is not as good as ordinary floor drains. However, as experts recommend that the room should not be installed and installed too much floor drains, there are currently some floor drains that are dual-purpose.

1. In the hot summer, the floor drain should also be cleaned. Otherwise, the wet bathroom and the small floor drain will easily multiply bacteria. The implementation of this method can often disinfect the floor drain. Soak the unused old towels in the disinfectant. After ten minutes, wring the towels half dry and cover them on the floor drain. Because the towels are wet, all the gaps on the floor drain grate can be blocked for disinfection. If possible, spray the disinfectant on the towel every few hours, so as to ensure a tight seal and achieve a disinfecting effect. However, if the towel dries, the disinfection effect will naturally disappear.
2. See the special floor drain for washing machines sold on the market. There is a rotatable cover in the center, which can be covered when not in use and unscrewed when used, which is very convenient. When decorating, ask the decorator to make a special cover for the floor drain. A small handle is embedded in the cover. When you want to use the floor drain, you can pull the cover off. When not in use, the cover is buckled on the floor drain. The bad smell from the pipe or downstairs will definitely not come up.
3. Generally speaking, the appearance of water leakage in the bathroom is caused by the three places of floor drain, wall corner and pipe root. Because there are many interfaces and gaps, there is water leakage. If it is determined that it is caused by floor leakage, then Under normal circumstances, it is because the floor drain is not tightly connected with the sewer interface device, resulting in a gap, so water leakage occurs. The solution can be used to open the floor drain and reinstall it to solve the waterproof problem. Rigid materials such as plugging spirit and China Nuclear 2000 can be used to paint and partially waterproof the joint between the pipe wall and the cement layer to solve the problem. There is no need at all. Do all waterproofing works.
