Common sense of purchasing instant electric faucet

When purchasing a faucet, you can better turn, look, want, test and know. When you turn the handle, it means that the valve element is good, and the surface is bright like a mirror, which means that the coating is good. The products produced by manufacturers that can provide inspection books can better guarantee the quality, experience the water flow personally, and feel the effect of the bubbler. The brand ensures after-sales service. What should we do? Let me tell you.

Look at the surface: the coating should be as bright as a mirror. After the faucet is polished and shaped, the surface should be nickel or chromium plated to oxidize the waterproof faucet. After nickel or chromium plating, the faucet should be subject to a medium hydrochloric acid test. After the test, the coating should have no signs of corrosion within a certain period of time. It is known that only faucets passing neutral salt spray test can leave the factory. When purchasing, consumers should better arrange the faucet at a place with sufficient light for observation. The surface of the faucet should be as bright as a mirror, free of any oxidation freckles, burnt traces, pores, bubbles, missing plating, and even luster; No burr or sand by hand; After pressing the faucet with your finger, the fingerprint will spread quickly and it is not easy to attach dirt.

Rotating handle: it feels that the light valve core is good, and the steel ball valve core has good pressure resistance, but the defect is that the rubber ring that plays a sealing role is easy to wear and will soon age. Compared with the steel ball valve core, the ceramic valve core is more heat-resistant and wear-resistant. At the same time, the ceramic valve itself has excellent sealing performance, so it can achieve a high opening resistance, and will not cause water nozzle leakage due to the wear of the valve core. The faucet with ceramic valve element is more comfortable and smooth in hand, and can be opened and closed quickly. Since the valve core is inside the faucet, the consumer cannot see the valve core when shopping, but the consumer can judge whether the valve core is good or bad according to the feel when turning the handle. As usual, consumers turn the handle up, down, left and right. If they think it is light and there is no sense of blockage, it means that the valve element is better.

Water flow test: rich and soft foam indicates that the bubbler is better. When purchasing, consumers should try to choose the faucet with the bubbler, and feel the water flow with their hands. Soft and rich water foam (water bubble content) indicates that the quality of the bubbler is better. The bubbler usually has six layers and is usually composed of a metal mesh cover (plastic part). When the water flows through the mesh cover, it will be cut into a large number of small water columns mixed with air, so that the water will not splash everywhere.

Want to check the book: the quality is more guaranteed, and the main body of the faucet is usually red copper. The electroplating quality of products made of brass can guarantee the best. The higher the purity of red copper, the better the electroplating quality, and the less easily the electroplating layer on the surface is corroded. In order to reduce costs, some manufacturers choose zinc alloy to replace red copper. Although it is allowed to use zinc alloy materials to replace red copper, zinc alloy electroplating quality is poor and corrosion resistance is not strong. Generally speaking, consumers can use the method of weight estimation to identify when purchasing, red copper is heavier and harder, and zinc alloy is lighter and softer. But the quality of the faucet should not be judged by weight alone, "because some manufacturers can also make the faucet heavier by increasing the wall thickness of the faucet or adding other metal materials". Consumers are better able to ask the salesperson for the test report of the product. If the test report confirms that the product is qualified, it is "not a problem".

Brand recognition: when choosing a brand, the after-sales service will be more secure. Consumers should go to the formal market and supermarkets to purchase electric faucets. Brand goods have the manufacturer's brand identity, and informal products or inferior products are often only pasted with some paper labels, or even without any marks. The tap packing box shall also have the manufacturer's brand logo, quality warranty and after-sales service card.
