First, how to choose the basin faucet
1. Look at the appearance of the basin faucet: the coating is bright and beautiful
After the basin faucet grinding and polishing molding, the surface should be plated with nickel or chromium to prevent the basin faucet oxidation, nickel or chromium plating on the basin faucet medium hydrochloric acid test, after a certain period of time after the test coating should not rust phenomenon. It is understood that only the basin faucet that has passed the neutral salt spray test can leave the factory.
When consumers buy, it is best to place the basin faucet in a well-lit place to see, the surface of the basin faucet should be bright like a mirror, without any oxidation spots, burn marks, no pores, no bubbles, no leakage plating, uniform color; Touch no burrs or sand grains by hand; After pressing the faucet with your finger, the fingerprint spreads quickly, and it is not easy to attach dirt.
2. Turn the handle of the basin faucet: soft and easy
Common basin faucet spool has steel ball valve core and ceramic spool. The steel ball valve core has good pressure resistance, but the disadvantage is that the rubber ring that plays a sealing role is easy to lose and will soon age. Compared with the steel ball valve core, the ceramic valve core is more heat and wear resistant, and the ceramic valve itself has good sealing performance, so it can achieve a high resistance to opening times, and will not cause the water nozzle to leak due to the wear of the valve core. The faucet with ceramic spool feels more comfortable and smooth, and opens and closes quickly.
Because the spool is inside the basin faucet, consumers cannot see the spool when purchasing, but consumers can simply judge the spool according to the feel of the handle when turning. Generally speaking, consumers turn the handle up, down, left and right, and if they feel light and without blocking, the spool is better.
3, recognize the brand: choose the faucet brand after-sales service is relatively perfect
Finally, consumers should go to regular markets and supermarkets to buy brand faucets. Brand goods have the manufacturer’s brand identity, informal products or quality products often only paste some paper labels, or even no marks. Basin faucet packaging box should also have the faucet manufacturer’s brand identity, quality guarantee certificate and after-sales service card.
4, check the faucet quality test book: protect rights and interests
In general, consumers can use the method of weight evaluation to identify when purchasing, brass is heavier and harder, zinc alloy is lighter and softer. However, the relevant experts of the main materials department of the Geda decoration believe that the quality of the basin faucet should not be determined by weight alone, “because some faucet manufacturers can also make the basin faucet weigh heavier by increasing the wall thickness of the basin faucet or adding other metal materials.” Consumers are best to ask the sales staff for the product test report, if the test report finds that the product is qualified, then “the problem is not big”.
In addition, consumers should choose a more durable integral casting basin faucet. The whole casting basin faucet sounds more dull, and consumers can judge whether the basin faucet is cast as a whole by beating the basin faucet when purchasing.
5, see the water flow: foam rich, soft
When purchasing, consumers should try to choose a basin faucet with a bubbler, and feel the water flow by hand, and the water flow is soft and foaming (water bubble content) rich, indicating that the bubbler quality is better. The bubbler generally has six layers, usually composed of a metal mesh cover (partly plastic), and the water passing through the mesh will be cut into a large number of small water columns with air in the middle, so that the water will not splash around.
Second, what size is the basin faucet
Generally, it is 1/2 inch, commonly known as 4 points, that is, the metric system of 15mm.
Imperial exchange table: 1/2 inch =15mm=4 minutes 3/4=20mm=6 minutes 1 inch =25mm, commonly known as 1 inch 1 1/4=32mm, commonly known as 1 inch 2 1 1/2=40mm, commonly known as 1 inch and a half 2 inches =50mm, commonly known as two inches.
It can be seen that the selection of basin faucets needs to pay attention to various factors, such as choosing a basin faucet with a bubbler as far as possible, and feeling the water flow by hand, the water flow is soft and foaming (water bubble content) rich, indicating that the bubbler quality is better.
