Look at the surface first. The main body of the Basin Faucet is cast from brass, after grinding and polishing, and then chrome-plated and other surface treatments. Regular product body casting and surface treatment have strict process requirements, and after neutral salt spray test, there should be no rust within the corresponding period. Therefore, when choosing a faucet, you should pay close attention to its surface, touch it without burrs, observe no pores, corrosion marks, no oxidation spots, crystal clear and shiny, and feel the thickness of the coating. The surface coating of the faucet is galvanized, titanium-plated, spray-painted, etc. The thickness of the coating is better, and the surface of the coating can be observed with eyes to see if it is bright. The coating of imported faucets is thicker and is not easy to fall off and oxidize. The electroplating layer should have a protective film, and the electroplating layer without a protective film is easy to fade. Gently turn the handle, whether it is light and flexible, and whether there is a sense of blocking and stagnation. A faucet that switches seamlessly, effortlessly, and doesn't slip is better. Inferior gaps are large, and the sense of obstruction is large. Knocking on the main body of the faucet, whether the sound is dull, and carefully observe the faucet interface, whether it is a copper body, if the sound is crisp when tapping, it may be made of stainless steel and other materials, of course, it is worse. Look at the various parts of the faucet, especially whether the main parts are tightly assembled. The valve body and handle of a good faucet are all made of brass, which is heavy and has a dignified feeling. Check the various parts of the faucet and observe whether the assembly is tight and loose. Generally, single-handle mixing Basin Faucets are attached with installation dimension drawings and operating instructions when they leave the factory. Before installation and use, the product packaging should be opened to check the certificate of conformity, etc., so as to avoid the use of "three-no" products.
If it is imported goods, you should be extra careful. In addition, it should be checked whether the accessories are complete. Generally, the accessories should be equipped with: (1) a full set of fixing bolts and fixed copper sheets and gaskets; (2) a full set of washbasin lifting water remover; (3) two water inlet pipes.
