First, identify the brand, find a brand with after-sales service consumers should be to the formal fashion when buying taps, find a well-known brand, so that you can get more perfect after-sales protection, informal products often do not have any mark or just on some paper labels, formal faucet packaging box should also have brand identification, quality assurance and after-sales service. Remind everyone to be cautious when buying and not to listen to other people’s nonsense. Second, to observe the appearance, the faucet surface plating to be as bright as a mirror faucet in the grinding and polishing molding, in order to prevent the faucet from being oxidized, will be plated on its surface with a layer of nickel or chromium, nickel or chromium has the function of resistance to neutral hydrochloric acid, in a long time to protect the faucet from corrosion. When buying, it is best to place the faucet in a well-lit place to inspect, the surface of the faucet without oxidation spots, no stomata, no plating and bubbles and scorch marks, even color without burrs and grit is a good product, there is a finger press the faucet, fingerprints spread quickly and without marks, and not easy to attach dirt. Third, quality testing, quality is more guaranteed faucet body is generally brass. The plating quality of products made of brass is best guaranteed, the higher the purity of the brass the better the plating quality and the more resistant to corrosion the surface layer. Some manufacturers choose zinc alloy instead of brass in order to reduce the cost, although the state allows the use of zinc alloy material instead of brass, but the zinc alloy plating quality is poor, corrosion resistance is not strong. In general, consumers can use the method of estimating the weight for identification when shopping, brass is heavier and harder, zinc alloy is lighter and softer. Fourth, swivel handle, feel light spool good faucet spool is usually steel ball spool and ceramic spool. The steel ball valve core has good pressure resistance, but the rubber sealing ring is easy to wear and age quickly. The ceramic spool is more heat resistant and wear resistant, and has good sealing properties, so it can be opened more often. No spout drips due to spool wear. The faucet with a ceramic spool is also more comfortable and smooth to the touch, and opens and closes quickly. You can simply judge the valve spool according to the feel when turning the handle. In general, consumers turn the handle up, down, left and right, if it feels light and non-stop, it means the valve spool is better. Fifth, test the water flow, to foaming rich in the purchase of the faucet, open the faucet water check, choose a faucet with a bubbler, and feel the water flow with your finger touch, the water flow is soft and rich in foam that the quality of the bubbler is better. The frother is usually six-ply and usually consists of a metal mesh cover, through which the water flow is split into many fine water columns, which are interspersed with air so as not to splash the water.
