Buy a faucet, what to choose? How to choose when buying?

From old-fashioned cast iron to electroplated knob type to double-temperature and double-control stainless steel ... The upgrading speed of faucets is accelerating day by day. Many people will comprehensively consider the material, function and modeling light when purchasing faucets, and many people will also consider water saving and durability. In fact, a really good faucet should have the characteristics of water saving, durability, humanization, easy cleaning, environmental protection and convenience. 1, water-saving secret weapon 1: steel ball valves and ceramic valves are mostly used in the built-in valve core of the valve core faucet. The steel ball of steel ball valve is durable and has strong compression resistance, but the disadvantage is that the rubber ring that plays a sealing role is easy to wear and will soon age. The ceramic valve itself has good sealing performance, and the faucet with ceramic valve core feels more comfortable and smooth, which can realize high opening resistance and quick opening and closing, and solve the problems of running, leaking, dripping and leaking. Secret weapon 2: bubbler On weekdays, if you pay attention, you will find that the high-end faucet water flow is soft and comfortable as fog and will not splash around. The secret weapon of these faucets is to install a bubbler, which can fully mix the flowing water and air to make the water flow have a foaming effect. With the addition of air, the scouring ability of water is improved a lot, thus effectively reducing the water consumption. Secret weapon 3: reach under the faucet and the faucet will open automatically. When you leave, the faucet will close automatically. This is an automatic water-saving faucet. At present, this kind of products are mostly used in public toilets, which has the advantages of convenience and hygiene. However, not all automatic faucets have water-saving function. Some faucets are slow to respond because of poor quality, and the water comes out slowly when the hand is near, and closes slowly when the hand is away, but a lot of water flows away in vain. Therefore, it is best to conduct field inspection and strictly control the purchase of such faucets. Secret weapon 4: old faucets and water pipes made of traditional materials are easy to rust and pollute water quality. When you get up early, you need to drain the yellow water in the pipeline first. But stainless steel and copper faucets and water pipes will not rust. In addition, the copper faucet has the function of sterilization and belongs to a healthy product. Definition 2: Whether a durable faucet is durable depends mainly on the surface treatment process. Tested in acidic high-temperature environment with PH value close to 3, it is intact for more than 4 hours, indicating that its surface treatment process is excellent. For example, some faucets adopt patented stainless steel ball valve technology, which can achieve the effect of "the repair rate is less than 65,438+1100000, and it can still be operated freely after 500,000 switches". Definition 3: Humanization At present, many humanized designs have been added to the faucets on the market. For example, a pull-out kitchen faucet has two modes: columnar water outlet and jet water outlet, which can be easily changed by pressing the button on the top of the shower head. The drawable 1.5-meter-long stainless steel hose can reach anywhere the operator needs. For another example, some sinks are designed with deep auxiliary tanks to save water when washing small, and adding a silencing pad at the bottom of the sink can also reduce the sound of water flow; For another example, some sinks are specially designed with overflow ports, so that the water overflowing from the sink can flow safely to the sewer without worrying about the consequences of turning off the faucet. Definition 4: Easy to clean Because of the cooking habits of China people, the kitchen fume is large, so the faucet is easy to get oil stains and water stains, and the surface of the faucet is easy to lose luster after repeated cleaning. The kitchen faucet treated by aerospace science and technology PVD technology can withstand the brushing of steel velvet and various cleaning agents, and is not faded, corroded, greasy, easy to clean and wear-resistant. Definition 5: The environmental protection of the environmental protection faucet is manifested in the lead content in the water, which is mainly caused by the water scouring the waterway. At present, the waterways of some faucets are pure copper to ensure their environmental protection. Low-temperature welding technology is adopted between the copper inlet pipe under the stage and the faucet body to maintain the high strength of the product, and special welding materials are used, which never contain cadmium. Definition 6: The convenience of the kitchen faucet mainly refers to its cooperation with the sink. For example, the traditional sink drainer needs to be cleaned regularly because of food waste such as broken slag, vegetable powder and tea. The use of portable super-large cage drainer increases the storage space of garbage and only needs to remove garbage at one time. For another example, in the traditional central hole design, it often happens that items are placed to cover the lower outlet, resulting in water accumulation. Adopt water back position design, effectively use space and prevent water accumulation.
