Water is the source of life, and people use water every day. Therefore, the faucet is a necessity in life. This small item is closely related to our life. When the home is renovated, the choice of the faucet naturally becomes a necessary course. How can I choose a reliable quality? What is the beautiful faucet that saves water?
First, look for the brand, identify the brand with after-sales service
When consumers buy faucets, they should go to formal fashion and find well-known brands, so that they can get more perfect after-sales protection. Informal products often do not have any mark or just some paper labels, and should also be in the regular faucet box. Brand identity, quality assurance and after-sales service. Remind everyone to buy is to be cautious, can not listen to others.
Second, observe the appearance, the surface plating 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 is plated on the surface. The 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 area. There are no oxidized spots on the surface of the faucet, no pores, no leakage and bubbles, and burn marks. The color is uniform and there is no burr and sand. After pressing the faucet with a finger, the fingerprint spreads quickly and has no trace, and it is not easy to adhere to dirt.
Third, quality inspection, quality is more guaranteed
The main body of the faucet is generally brass. The quality of the products made of brass is guaranteed to be the best. The higher the purity of the brass, the better the quality of the plating, and the more corrosion-resistant the surface is. In order to reduce the cost, some manufacturers choose zinc alloy instead of brass. Although the country allows the use of zinc alloy materials instead of brass, the zinc alloy plating quality is poor and the corrosion resistance is not strong. In general, consumers can use the method of estimating weight when purchasing. Brass is heavier and harder, and zinc alloy is lighter and softer.
Fourth, rotate the handle, feel the light spool is good
The faucet spools are usually steel ball spools and ceramic spools. The steel ball valve core has good pressure resistance, but the rubber sealing ring which is used for sealing is easy to wear and aging is fast. The ceramic valve core is more resistant to heat and wear, and has a good sealing performance, so the number of opening resistance will be more. No faucet dripping due to wear of the valve plug. The faucet with ceramic valve core is more comfortable and smooth in hand, and opens and closes quickly. When purchasing, you can easily judge whether the spool is good or bad according to the feel when turning the handle. In general, the consumer turns the handle up, down, left, and right. If it feels light and has no blockage, the spool is better.
Fifth, test the water flow, subject to foaming
When you buy a faucet, open the faucet to check the water, select the faucet with a bubbler, and touch the water with your fingers. The water flow is soft and the bubble content is rich, indicating that the bubbler is of good quality. The bubbler generally has six layers, usually consisting of a metal mesh cover. After the water flows through the mesh cover, it is divided into a number of small water columns, which are interspersed with air so as not to splash the water.
