1. Identify the brand and find the brand with after-sales service
When buying faucets, consumers should go to formal fashion and find well-known brands, so that they can get a more perfect after-sales guarantee. Informal products often do not have any symbols or just some paper labels. The formal faucet box should also be With brand identity, quality assurance and after-sales service. Prompt us to buy it must be cautious, not to listen to others bragging.
2. Investigate the exterior, the faucet's exterior coating should be as bright as a mirror
In order to prevent the faucet from being oxidized, the faucet will be plated with a layer of nickel or chromium to prevent the faucet from being oxidized. Nickel or chromium has the function of resisting neutral hydrochloric acid and maintains the faucet from corrosion for a long time. When buying, it is best to place the faucet in a place with sufficient light to see. The faucet has no oxidized mottle, no porosity, no plating and blistering, and scorch marks. The color is uniform without burrs and sand. After pressing the tap with your finger, the fingerprints spread out quickly and without traces, and it is not easy to attach dirt.
3. Quality inspection, quality is more assured
The faucet body is generally brass. The electroplating quality of products made of brass can best ensure that the higher the purity of the brass, the better the electroplating quality, and the less likely the external plating layer is to be corroded. In order to reduce costs, some manufacturers choose zinc alloy instead of brass. Although the country allows the use of zinc alloy materials to replace brass, zinc alloy plating has poor quality and poor corrosion resistance. Generally speaking, consumers can choose the method of estimating the weight when purchasing. Brass is heavier and harder, and zinc alloy is lighter and softer.
4. Rotate the handle, feel simple and good valve core
Faucet spools are generally steel ball spools and ceramic spools. The steel ball valve core is good in pressure resistance, but the rubber sealing ring that has a sealing effect is easy to wear and aging quickly. The ceramic valve core is more heat-resistant and wear-resistant, and has an excellent sealing function, so the number of opening times will be more. No drip of the water nozzle due to valve core wear. The faucet with ceramic spool is more comfortable and smooth to the touch, open and closed quickly. When buying, you can easily judge whether the valve core is good or bad according to the feel when rolling the handle. In general, consumers scroll up, down, left, and right with the handle. If it feels simple and does not have a sense of blockage, it means that the valve core is better.
5. Test water flow, subject to rich foam
When we buy a faucet, turn on the faucet to check the water, select the faucet with a bubbler, and feel the water flow with our 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, and is generally composed of a metal mesh cover. After the water flow passes through the mesh cover, it will be divided into many fine water columns, with air interposed therebetween, so as not to splash the water.
