The Beijing Municipal Bureau of Industry and Commerce recently entrusted the National Building Materials Testing Center to conduct inspections on 11 types of building materials such as toilets, faucets and latex paints sold in 11 building materials markets. As a result, more than 70 kinds of “problem building materials†were found. Among them, the largest number of unqualified taps was 21 samples. So, how can consumers avoid buying inferior or even unqualified faucets?
Experts advise: When consumers purchase the faucet, it is best to be able to turn, see, want, try, know, when turning the handle feels light Description of the valve core is good, the surface is bright as a mirror that the coating is good, can provide test book manufacturers The products can guarantee the quality, and experience the water flow to perceive the bubbler effect. The branded products show that after-sales service is guaranteed.
Turn handle: feel light valve is good
Common faucet spools have steel ball spools and ceramic spools. Steel ball valve core has a good resistance to pressure, but the disadvantage is that the rubber ring from the sealing effect is easy to wear and will soon be aging. Compared with the steel ball valve core, the ceramic valve core is more heat-resistant and wear-resistant. At the same time, the ceramic valve itself has a good sealing performance, so it can achieve a high degree of resistance to opening, and will not cause water nozzle drip due to valve core wear. Ceramic faucet, feel more comfortable, smooth, and open and close quickly.
Since the valve plug is inside the faucet, the consumer cannot see the valve plug when purchasing, but the consumer can easily judge the quality of the valve plug based on the feel of the rotating handle. In general, if the consumer rotates the handles up, down, left, or right, it feels good if they feel light and free from blockage.
To test the book: quality is more assured
The faucet body is generally brass. The quality of the plating product made of brass can be guaranteed to be the highest. The higher the purity of the brass is, the better the plating quality is, and the less plating layer on the surface is less likely to be corroded. Some manufacturers use zinc alloy instead of brass in order to reduce costs. Although the state allows the use of zinc alloy instead of brass, the quality of zinc alloy plating is poor and corrosion resistance is not strong.
In general, consumers can use the method of weight estimation when purchasing. Brass is heavier and harder, and zinc alloy is lighter and softer. However, the experts of Kuda's decorative main material department believed that the quality of faucets should not be judged by their weight alone, “because some manufacturers can increase the thickness of the faucet or add other metal materials, it can also make the faucet pick up more.†Consumers are advised to ask the sales staff for a test report of the product. If the test report says that the product is qualified, the problem is not serious.
In addition, consumers should choose a more durable overall casting faucet. The sound of the overall cast faucet tapping is even more boring. Consumers can judge whether the faucet is cast as a whole by tapping on the faucet.
Test water flow: rich and soft foam indicates better bubbler
Consumers should choose a faucet with a bubbler as far as possible, and feel the water flow with their hands. The water flow is soft and foamy (water bubble content), indicating that the bubbler quality is better. The bubbler generally has six layers, usually consisting of a metal mesh cover (partly plastic). When the water passes through the mesh cover, it will be cut into a large number of tiny water columns with air interposed between them so that the water does not splash around.
Recognize the brand: choose the brand after-sales service is more secure
Finally, consumers should go to the formal market and supermarkets to purchase branded taps. Branded products have manufacturer's brand identity, and non-regular products or quality products are often only pasted with some paper labels, even without any mark. The faucet packing box should also have the manufacturer's brand identity, quality assurance and service card.
