Tap to buy skills have five principles to observe

First, look for brands and identify brands with after-sales services

Consumers should go to formal fashion when buying faucets, and identify well-known brands, so that they can get more perfect after-sale protection. Non-regular products often do not have any marks or just some paper labels. The formal faucets should also be inside the box. Brand identity, quality assurance and after-sales service. Remind everyone to buy it must be careful, you can not listen to others blowing.

Second, observe the appearance, the surface coating of the faucet should be bright as a mirror

After the faucet is formed by grinding and polishing, in order to prevent the faucet from being oxidized, a layer of nickel or chromium will be plated on the surface of the faucet. Nickel or chromium has the function of resisting neutral hydrochloric acid and protects the faucet from corrosion for a long time. When purchasing, it is best to place the faucet in a well-lit place. The surface of the faucet is free of oxidation spots, air holes, missing plating and blisters, and scorch marks. The color is uniform without glitches and sand grains. It is a good product. After pressing the tap with your finger, the fingerprint spreads quickly and without traces, and it is not easy to attach dirt.

Third, quality inspection, quality assurance

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.
