1. The handle: feel the light spool is good
Common faucet spools designed by faucet manufacturers include steel ball spools and ceramic spools. The steel ball valve core has good resistance to pressure, but the disadvantage is that the rubber ring that acts as a seal is easy to wear and will soon age. 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 good sealing performance, so that it can achieve a high number of opening resistances, and no faucet leakage due to valve core wear. The faucet of the ceramic valve core of the faucet manufacturer is also more comfortable and smooth to the touch, and opens and closes quickly.
2. To test the book: quality is more guaranteed
The main body of the faucet is generally brass. The quality of the products made of brass is guaranteed to be the best. The higher the purity of the brass, the better the plating quality, and the harder the surface plating layer is. In order to reduce the cost, some faucet manufacturers use zinc alloy instead of brass. Although the country allows the use of zinc alloy materials instead of brass, the zinc alloy plating quality is poor and the corrosion resistance is not strong.
Consumers can use the method of weight estimation to make the purchase. The brass is heavier and harder, and the zinc alloy is lighter and softer. However, experts from faucet manufacturers believe that the quality of the faucet should not be judged by weight alone. "Because some faucet manufacturers can make the faucet heavier by increasing the wall thickness of the faucet or adding other metal materials." Consumers should ask the sales staff of the faucet manufacturer for the test report of the product. If the test report determines that the product is qualified, the problem is not big.
3. Test water flow: foam is rich and soft, indicating that the bubbler is better
Consumers should choose a more durable overall casting faucet. The overall cast faucet is more dull when knocked, and consumers can judge whether the faucet is cast as a whole by tapping the faucet when purchasing.
When purchasing, try to choose a faucet with a bubbler, and feel the water flow with your hand. The water flow is soft and foaming (the bubble content of the water flow) is rich, indicating that the bubbler is of good quality. The bubbler generally has six layers, usually consisting of a metal mesh cover (partially plastic). When the water flows through the mesh cover, it is cut into a large number of small water columns with air in between, so that the water does not splash around.
4. Recognize the brand: choose the brand after-sales service is more secure
