The floor drain is an important interface connecting the drainage system with the indoor floor. As an important part of the drainage system in the residence, its performance directly affects the quality of the indoor air, and is very important for the odor control in the bathroom. Although the floor drain is small, there are many issues to consider when choosing a suitable floor drain.
1. Understand the structure of the floor drain
Under the premise that the existing building structure cannot be changed, floor drain deodorization should be the best way to solve the odor problem. How to deodorize the floor drain? Then you have to understand its structure first. Ordinary floor drains generally include a floor drain body and a floating cover. The floor drain body refers to the part of the floor drain that forms a water seal. The main part is the water storage bay. Since many floor drains are currently deodorized mainly by water seals, the depth of the structure and whether the design is reasonable determine the sewage discharge capacity and odor resistance of the floor drain. When there is water in the floating cover, it can float up and down with the water in the floor drain body. Many floating covers are connected with a bell cover in addition. When there is no water or little water, the sewer pipe will be covered to prevent odor from returning to the room from the sewer pipe.
2. The purpose of the floor drain is exclusive
From the function of use, the floor drain is divided into two types: general use and washing machine special. The special floor drain for washing machines has a round hole in the middle, which can be inserted into the drainpipe, and is covered with a rotatable cover. It can be closed when not in use, and unscrewed when in use. It is very convenient, but the anti-odor function is not as good as ordinary floor drains. However, since experts suggest that there should be as little as possible to set and install floor drains in the room, there are currently some floor drains that are dual-purpose.
Three, material selection is particular
Floor drains on the market are mainly divided into three types: stainless steel floor drains, pvc floor drains and all-copper floor drains. Since the floor drain is buried below the ground and requires good sealing, it cannot be replaced frequently, so it is very important to choose an appropriate material. Among them, the all-copper floor drain has begun to occupy an increasing share because of its excellent performance. Stainless steel floor drains were quite popular in the past few years because of their beautiful appearance, but according to relevant professionals, stainless steel is expensive and has a thin coating, so it will not escape the fate of rust in a few years; while pvc floor drains are cheap and have a good deodorizing effect. Not bad, but the material is too brittle and easy to age, especially in the north where the winter temperature is low, and it will not take too long to replace it, so the market is not optimistic; at present, the most common floor drain in the market is full copper chrome plating. Its coating is thick, even if it takes a long time In addition to copper rust, it is easier to clean. Under normal circumstances, the all-copper floor drain can be used for at least six years.
Four, deodorant floor drain competition
In addition to dispersing water freely, deodorization is the most critical. The floor drains on the market now basically have the function of deodorization. According to the advanced degree of deodorization principle, facilities and methods, the price can not help but be the same. When purchasing, you should choose the one that suits your needs.
According to the deodorant method, floor drains are mainly divided into three types: water deodorant floor drains, sealed deodorant floor drains and three-proof floor drains. The water and odor-proof floor drain is our most traditional and common. It mainly uses the tightness of water to prevent the emission of peculiar smell. In the structure of the floor drain, the water storage bay is the key. Such a floor drain should try to choose a relatively deep water storage bay, not just for a beautiful appearance. According to relevant standards, the body of the new floor drain should ensure that the height of the water seal is 5cm, and have a certain ability to keep the water seal from drying up, so as to prevent pan-odor. Now there are some ultra-thin floor drains on the market, which are very beautiful, but the anti-odor effect is not very obvious. If your bathroom space is not a bright room, then it is best to choose some traditional ones. The airtight deodorant floor drain refers to adding an upper cover to the floating cover to seal the floor drain body to prevent odor. The advantage of this floor drain is that it looks modern and avant-garde, but the disadvantage is that you have to bend down to lift the cover every time you use it, which is troublesome. But recently, an improved sealed floor drain has appeared on the market. There is a spring under the upper cover. When using the upper cover, the upper cover will pop up, and it will be more convenient to step back when not in use. The three-proof floor drain is the most advanced anti-odor floor drain so far. It installs a small floating ball at the drain pipe at the lower end of the floor drain body, and uses the water pressure and air pressure in the sewer pipe to hold the ball against the ball so that it is completely closed with the floor drain, so as to prevent odor, insects and overflow. .
5. Misunderstandings for purchase and installation
After understanding the basic situation of the floor drain, you should pay attention to some problems before purchasing and installing, and don’t go into misunderstandings.
The first is size. When real estate developers hand over the houses, the reserved holes for drainage are relatively large, which need to be repaired by decoration personnel. Many consumers choose the floor drain according to the size of the drain outlet trimmed by the decoration team at the end of the decoration, but the floor drains on the market are all standard sizes, so it often happens that they cannot choose a satisfactory product. Therefore, consumers are reminded to choose their favorite floor drain at the design stage of decoration, and then construct the drain according to the size of the floor drain. In addition, the opening diameter of the floor drain grate should be controlled between 6 and 8mm to prevent hair, sludge, sand and other dirt from entering the floor drain.
The second thing that should be grasped is that the water inlet of the multi-channel floor drain should not be too many. The multi-channel floor drain is a product developed in recent years. A body usually has 3 to 4 water inlets (for washbasin, bathtub, washing machine and floor drainage). This structure not only affects the drainage of the floor drain, but also does not conform to the actual design situation. . Therefore, there should not be too many water inlets for the multi-channel floor drain, and two (ground and bathtub or ground and washing machine) can meet the needs.
