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.
Fourth, rotating handle, feel good valve core
The faucet valve is usually a steel ball valve and a ceramic valve plug. Steel ball valve core has good compression resistance, but the rubber sealing ring that acts as a seal is easy to wear out and has a quick aging. The ceramic valve core is more heat-resistant and wear-resistant, and has a good sealing performance, so the number of resistance-to-opening times will be more. No leakage of the nozzle due to worn valve cores. Ceramic faucet, feel more comfortable, smooth, and open and close quickly. When buying, it is easy to judge whether the spool is good or bad based on the feel when turning the handle. In general, if the consumer rotates the handles up, down, left, or right, it feels good if they feel light and free from blockage.
Fifth, test water flow, based on rich foam
Remind: When you buy a faucet, turn on the faucet to check for water, select a faucet with a bubbler, and feel the water flow with your fingers. The water flow is soft and rich in foam indicates that the bubbler is of good quality. The bubbler generally consists of six layers. Usually, it consists of a metal mesh cover. After passing through the mesh cover, the water will be divided into many small water columns with air interposed so as not to spill water.
