floor drain is an important part connecting sewer drainage pipe and indoor ground. The performance of floor drain directly affects the indoor environmental quality and air quality. Now, faced with a great variety of products, and every family “ Wang Po sells melons ” How should we choose to publicize? Which floor drain is good? Look at the sales volume? Look at the brand? Look at the price? Don't worry, Xiaobian will share with you today the shopping guide for floor drains in the eyes of experts

which floor drain is good? 1. Material comparison

cast iron floor drain: it is cheap and has been used in early China. It is easy to rust, the dirt hanging on it is not easy to clean up, it is not beautiful, and it is inconvenient to transport and install. It has been basically eliminated by the market

stainless steel floor drain: the price of stainless steel floor drain is moderate and beautiful. Due to different materials and thickness, the price also varies greatly. 202 stainless steel floor drains are not corrosion resistant, and 304 and 306 stainless steel floor drains are corrosion resistant, so the price is also more expensive than 202

cast aluminum floor drain: medium price, light weight, rough surface, no grade, not used much

pvc floor drain: the price is cheap and the odor proof effect is good, but the material is too brittle and easy to age. Especially in the north, the temperature is low in winter, so it needs to be replaced in a short time, so the market is not optimistic

zinc alloy floor drain: cheap, chrome plated surface, lighter than copper, not corrosion resistant

all copper chromium plated floor drain: its coating is thick, and it is easy to clean even if it has copper rust after a long time. Generally, all copper floor drain can be used for at least 6 years

which floor drain is good? 2. Advantages and disadvantages of different styles

① buckle cup water seal floor drain

odor proof grade: ★

advantages: the price is cheaper

disadvantages: this kind of water sealed floor drain can not effectively prevent odor, is easy to block, and the drainage is slow

reason: the buckle cup water seal floor drain is a protruding piece on the back of the cover and forms a water seal inside the floor drain body to prevent odor. But because the water seal is very shallow, the effective water seal that really works is only about half a centimeter. As long as the toilet upstairs flushes, the positive and negative pressure in the pipe will destroy the water in the floor drain. The odor can enter the room unobstructed, and this floor drain cannot effectively prevent odor. And because of its own design defects, the floor drain is easy to block and the drainage is very slow

note: the national building drainage code expressly stipulates that this kind of shallow water sealed floor drain must be eliminated and prohibited from engineering and decoration

2. Spring floor drain and flap floor drain

odor proof grade: ★★

advantages: there are many choices of panel styles

disadvantages: these self sealing floor drains are not odor proof, easy to block, and have short service life

spring floor drain and flap floor drain (and some similar to non core, principle valve, floating ball, gear, etc.) these floor drains are collectively referred to as self sealing floor drains, which are opened when there is water by gravity and closed when there is no water. It seems to be odor proof, but it is quite different in practice

reason: because the water quality of the floor drain drainage is poor, as well as hair, etc., the sealing cover plate of these self sealing floor drains is easy to be stained. Once stained, if it is not tightly closed, it will leak air and not prevent odor. Also, if the hair goes down and wraps on the cover plate or is clamped in the middle of the floor drain core cover plate, it will cause blockage and leakage without odor prevention. This kind of mechanical floor drain, the spring is easy to fail, and other gear bearing covers are very easy to be damaged

3. Porous deep-water floor drain

odor proof grade: ★★★

advantages: good odor proof effect

disadvantages: the drainage speed is slow, and it is easy to be blocked for household use. Whenever a person takes a bath, he has to open the floor drain for cleaning, otherwise the floor drain will be blocked and cannot drain water. It's annoying to clean up every time! (and most of the inner cores of this floor drain can't be disassembled, so it's troublesome to clean)

reason: this floor drain has a good deodorization effect, but the porous water outlet is a very unscientific design, which will cause slow drainage and easy blockage, etc. The deep-water floor drain adopts porous water. If you hold the floor drain in your hand, it looks good. But the standard pipe left by the builder is 50mm in diameter, and the diameter of these deep-water floor drain cores is 35mm-38mm. Once the floor drain is installed, the water will flow out of the porous plane of the floor drain core. The distance between the pipe and the floor drain core is close to the porous plane of the floor drain core, which will cause resistance and affect the drainage speed, and these floor drains have no hair filter screen, Once something with hair or fiber in the drainage enters the floor drain, it will hang on the water outlet of the floor drain core to form a blockage
