1 turn handle: feel good spool
Common faucet spool with steel ball spool and ceramic spool. Steel ball valve has a good resistance to pressure, but the disadvantage is that the role of sealing rubber ring is easy to lose, will soon be aging. Compared with the steel ball valve, ceramic valve core is more heat resistant, ceramic valve itself also has good sealing performance, it can achieve a high frequency of resistance to opening, will not cause tap drip valve wear. The use of ceramic valve core, feel more comfortable, smooth, and open and close quickly.
As the valve core in the faucet, consumers can not see the spool when buying, but consumers can handle the handle to determine the quality of the spool according to the handle. In general, the consumer, the upper, lower, left and right to turn the handle, if the feeling of light, no sense of obstruction is better spool.
2 to test the book: quality assurance
The main body of the tap is brass. The quality of the products made with brass can be guaranteed, the higher the purity of brass, the better the quality of plating, the more difficult the surface of the plating layer corrosion. Some manufacturers in order to reduce costs, the use of zinc alloy instead of brass, although the state allows the use of zinc alloy materials instead of brass, zinc alloy plating quality is poor, but not strong corrosion resistance.
Consumers in the purchase can be used to determine the weight of the method of identification, heavier and harder brass, zinc alloy lighter soft. But KuoDa decorative material experts think, should not only use weight to determine the faucet quality, because some manufacturers tap by increasing the wall thickness or adding other metal materials, can also make the tap it heavier. Consumers had better ask the sales staff to test the product report, if the test report finds that the product is qualified, the problem is not.
3 test flow: Foam rich and soft that the bubble is better
Consumers should choose a more durable integral casting tap. The tap of the whole tap is more boring, and consumers can judge whether the tap is a whole casting by tapping the tap.
When buying, should try to choose the water faucet with a bubble, and to touch the feeling of water, soft water and foam (water bubble content) rich description of the bubble better quality. Generally six layers of foam, usually made of metal mesh cover (part of the plastic), the water flow through the network cover will be cut into a large number of small water column in the middle with air, so that the water will not splash around.
4 recognize the brand: choose brand after-sales service more secure
Consumers should go to the regular market and supermarket to buy brand taps. Brand products are manufacturers of brand identity, informal products or quality products are often only paste some paper labels, and even without any mark. There should also be the manufacturer's brand identification, quality assurance and after-sales service card.
