Turn handle: feel light valve is good
Common faucet spools have steel ball spools and ceramic spools. Steel ball valve core has a good anti-pressure capability, but the disadvantage is that the rubber sealing 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 core itself has good sealing performance, so it can achieve a high resistance to opening times, and will not cause water nozzle leakage 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.
Look at the appearance: the plating should be bright as a mirror
After the faucet is polished and cast, the surface should be plated with nickel or chromium to prevent oxidation of the faucet. After the nickel or chromium plating, a medium-sized hydrochloric acid test is performed on the faucet. After the test, the plating layer should be free of rust during a certain period of time. It is understood that only the faucets that pass the neutral salt spray test can be delivered. When consumers purchase, it is best to place the faucet in a well-lit place. The surface of the faucet should be bright as a mirror, without any oxidation spots, scorch marks, no air holes, no blistering, no leakage plating, and uniform color; The hands are free of burrs and grit. After pressing the tap with a finger, the fingerprints quickly spread out and the dirt is not easily attached.
To test: 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 estimating the weight when purchasing. The brass is heavier and harder, and the zinc alloy is lighter and softer. Experts advise that the quality of faucets should not be judged by their weight alone, because some manufacturers can also make the faucets heavier by increasing the wall thickness of faucets or adding other metal materials. 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.
