1. Turn the handle: feel the light spool is good
Common faucet valve cores include steel ball valve core and ceramic valve core. The steel ball valve core has good pressure resistance, but the disadvantage is that the sealing rubber ring is easy to wear and will quickly 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 good sealing performance, so it can achieve a high resistance to opening times, and will not cause the nozzle to drip due to the wear of the valve core. The faucet with ceramic valve core is more comfortable and smooth in hand, and opens and closes quickly.
Since the valve core is inside the faucet, consumers cannot see the valve core when purchasing, but consumers can simply judge whether the valve core is good or bad based on the feel when turning the handle. Generally speaking, consumers turn the handle up, down, left, and right. If it feels light and has no sense of blocking, it means that the valve core is better.
2. To check the book: the quality is more guaranteed
The main body of the faucet is generally brass. The electroplating quality of products made of brass can be guaranteed. The higher the purity of the brass, the better the electroplating quality, and the more resistant the electroplated layer on the surface 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 instead of brass, the quality of zinc alloy plating is poor and the corrosion resistance is not strong.
Consumers can use the method of weight estimation to identify when purchasing. Brass is heavier and harder, while zinc alloy is lighter and softer. However, experts in the main material department of Kuoda Decoration believe that the quality of faucets 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. It is best for consumers to ask the sales staff for the test report of the product. If the test report confirms that the product is qualified, the problem is not big.
3. Test the water flow: rich and soft foaming indicates a better bubbler
Consumers should choose a more durable integral casting faucet. The sound of integrally cast faucet is more dull when tapping. Consumers can judge whether the faucet is integrally cast by tapping the faucet when purchasing.
When purchasing, you should choose a faucet with a bubbler as much as possible, and feel the water flow with your hands. The soft water flow and rich foaming (water flow bubble content) indicate that the bubbler is of good quality. The bubbler generally has six layers and is usually composed of a metal mesh cover (part of which is plastic). When the water flows through the mesh cover, it will be cut into a large number of small water columns with air in the middle, so that the water will not splash around.
4. Brand recognition: after-sales service is more secure when choosing a brand
Consumers should go to regular markets and supermarkets to buy branded faucets. Branded products have the manufacturer's brand logo. Informal products or quality products are often only pasted with some paper labels, or even without any marks. The faucet packaging box should also contain the manufacturer’s brand logo, quality assurance certificate and after-sales service card.
