1. Light turning handle, good spool
Common faucet spools are steel ball spools and ceramic spools. The steel ball valve core has very good pressure resistance, but the disadvantage is that the rubber sealing ring that acts as a seal is easy to wear and will quickly 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 core itself has good sealing performance, so it can achieve a high number of resistance to opening, and will not cause the nozzle to leak due to valve core wear. The faucet with ceramic valve core is more comfortable and smooth, and opens and closes quickly. Because the spool is inside the faucet, consumers cannot see the spool when buying, but consumers can simply judge the quality of the spool based on the feel when turning the handle. Generally speaking, turning the handle up, down, left, and right, if it feels light and non-blocking, it means that the spool is better.
2.The surface coating should be as bright as a mirror
After grinding and polishing the faucet, the surface should be plated with nickel or chromium to be oxidized with a waterproof faucet. After the nickel or chrome is plated, the faucet is subjected to a medium-sized hydrochloric acid test. After the test, the coating should be free of rust. It is understood that only faucets that pass the neutral salt spray test can leave the factory. When buying, consumers are better to place the faucet in a place with sufficient light for inspection. The surface of the faucet should be as bright as a mirror, without any oxidation spots, scorch marks, no pores, no blistering, no leakage plating, uniform color; There are no burrs or grit in the hand. After pressing the faucet with your fingers, the fingerprints spread out quickly, and it is not easy to attach dirt.
3.Quality must be guaranteed
The faucet body is generally brass. The quality of electroplating made of brass products can ensure the highest quality. The higher the purity of brass, the better the electroplating quality, and the less likely the surface plating layer will be corroded. Generally speaking, consumers can use the estimated weight method to identify when buying. Brass is heavier and harder, and zinc alloy is lighter and softer. Experts remind that the quality of a faucet should not be judged solely by weight, because some manufacturers can also make the faucet heavier by increasing the wall thickness of the faucet or adding other metal materials.
4, rich water foam
Consumers should try to choose a faucet with a bubbler when they buy it, and feel the water flow with their hands. The softness and richness of the water flow (bubble content in the water flow) indicate that the quality of the bubbler is better. The bubbler generally has six layers, usually composed of a metal mesh cover (partly 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.
