Tips for buying a faucet

Household faucets are just-needed items. For consumers who don’t know what brand and price are considered good, you might as well learn the following points as a reference when purchasing, so as not to suffer from being fooled.
①Turn the handle, and the valve core feels light. Common faucet valve cores include steel ball valve cores and ceramic valve cores. The steel ball spool has good pressure resistance, but the disadvantage is that the rubber sealing ring that acts as a seal is easy to wear and age quickly. Compared with the steel ball spool, the ceramic spool is more heat-resistant and wear-resistant. At the same time, the ceramic spool itself has good sealing performance, so it can achieve a high resistance to opening times, and will not cause the nozzle to drip due to the wear of the spool. The faucet with ceramic valve core is more comfortable and smooth to the touch, and it opens and closes quickly. Since the spool is inside the faucet, you cannot see the spool when purchasing, but you can simply judge whether the spool is good or bad according to the feel when turning the handle. Generally speaking, turn the handle up, down, left, and right. If it feels light and there is no sense of blockage, it means that the valve core is better.
②To test, the quality is more guaranteed. The main body of the faucet is generally brass. The electroplating quality of products made of brass is the most guaranteed. The higher the purity of the brass, the better the electroplating quality, and the less likely the electroplating layer on the surface is to be corroded. In order to reduce costs, some manufacturers choose zinc alloy instead of brass. Although the country allows the use of zinc alloy instead of brass, the quality of zinc alloy plating is poor and its corrosion resistance is not strong. Generally speaking, the method of estimating the weight can be used for identification when purchasing. Brass is heavier and harder, and zinc alloy is lighter and softer. The quality of the faucet should not be judged by weight alone, because some manufacturers can also make the faucet heavier by increasing the wall thickness of the faucet or adding other metal materials. It is best to ask the salesperson for the test report of the product. If the test report confirms that the product is qualified, the problem is not big.
③ Look at the appearance, the coating should be as bright as a mirror. After the faucet is ground and polished, the surface should be plated with nickel or chrome to prevent oxidation of the faucet. After nickel or chrome plating, the medium-sized hydrochloric acid test should be carried out on the faucet. After the test, the coating should be free of rust within a certain period of time. Only faucets that have passed the neutral salt spray test can leave the factory. When purchasing, it is best to place the faucet in a place with sufficient light for inspection. Bubble, no missing plating, uniform color. There are no burrs and sand particles when you touch it with your hands. After pressing the faucet with your fingers, the fingerprints will quickly disperse, and it is not easy to attach dirt.
④Test the water flow, subject to rich foaming. When purchasing, try to choose a faucet with a bubbler, and feel the water flow with your hands. The water flow is soft and foaming (water flow bubble content) is rich, indicating that the quality of the bubbler is better. The bubbler generally has six layers and is usually composed of a metal mesh cover (some of which is plastic). When the water flows through the mesh cover, it will be cut into a large number of small water columns with air in the middle, so that the water will not be fragmented.
