When the kitchen is decorated, many people are very concerned about the large parts such as the range hood, the cooktop, the sink, etc. The small pieces such as the faucet are not taken care of. In fact, the small objects are also important to your kitchen life experience. Just recently, the home is in the renovation, and the faucet has been studied for a long time. Some experiences and experiences are shared with everyone for reference.

When choosing a kitchen faucet, the more I think about it is: Can it last for a long time? Will it pollute the water? Is it inconvenient to use? To solve these problems, we must first understand the structure of the faucet.

When the kitchen is decorated, many people are very concerned about the large parts such as the range hood, the cooktop, the sink, etc. The small pieces such as the faucet are not taken care of. In fact, the small objects are also important to your kitchen life experience. Just recently, the home is in the renovation, and the faucet has been studied for a long time. Some experiences and experiences are shared with everyone for reference.

When choosing a kitchen faucet, the more I think about it is: Can it last for a long time? Will it pollute the water? Is it inconvenient to use? To solve these problems, we must first understand the structure of the faucet.

The overall structure of the faucet is divided into a valve core, a main body and a surface layer. The valve core is the part that controls the flow of water in and out. It is the heart of the faucet. It can be seen here if it is durable. The main body is the main component of the faucet, that is, the bone. Most of the water pollution is that the material of this part is not good; the plating is the surface of the faucet. The substance, which is the skin of the faucet, is the value of the faucet.

I. Can it be used for a long time?
The faucet was turned off and off every day. We can’t remember how many times it was switched in a day, so the first question we considered when buying it was whether it could be used for a long time. When the switch is active, the faucet is in the spool, so if you want it to be used for a long time, it depends on the quality of the spool. The quality of the spool can be judged by whether it can withstand the long-term no-drip test. It is a life test for the spool. It is clearly stipulated in the national faucet testing standards that the no-drip test of the switch requires no less than 200,000 switching times. In addition to judging the quality from this test indicator, it can also be evaluated from the senses. Turning the handle up, down, left, and right, the light and unobstructed feeling indicates good quality.
At present, the ceramic valve core is the most suitable valve core material, and it is also widely used by many faucet manufacturers. It is the most cost-effective, because it is easy to take, and wear-resistant, hot and cold temperatures can be adapted for a long time. Although the impurities in the water may cause damage to the ceramic valve core, the tap water used by the residents is of good quality and can basically ignore this factor.

Shop TIPS:
Material selection: ceramic valve core, the most cost-effective.
Quality evaluation: The no-leak test of the switch requires no less than 200,000 switching times.
Sensory evaluation: turn the handle up, down, left, and right, light and unobstructed.

2. Will it pollute the water?
Before the faucet was exposed to frequent lead levels, the lead poisoning in the residents caused everyone to start panicking. Therefore, when purchasing the faucet, in addition to the quality, I will consider whether it will pollute the water.
If you look at the faucet that will pollute the water, you should look at the material of the main part that has been in contact with the tap water for a long time.
The main body of the faucet is mainly cast iron, plastic, zinc alloy, copper alloy and stainless steel. Cast iron is prone to rust, plastics are prone to aging, zinc alloys have poor stability and are prone to bursting, resulting in a short-term use, so it is not recommended to buy these three materials.
At home, copper alloy is the most suitable material for the main body. Because copper ions have a certain bactericidal effect, and bacteria can not produce antibodies, the inner surface of the copper faucet will not breed bacteria, which is no other way than other materials. This is why many brands now choose copper materials for faucets.

Brass in copper alloy is a combination of copper and zinc. Its mechanical properties, wear resistance and corrosion resistance make it the first choice for faucet materials. Brass is also divided into many types because of the copper content. At present, most of the faucets use H59 copper, which is 57% to 61% copper. In fact, some international sanitary ware brands even use H62 copper. The faucet is produced because H62 copper has a higher copper content than H59 copper and has better corrosion resistance.

In addition to copper and zinc, brass also contains traces (less than 0.5%) of lead. When the faucet is exposed to lead poisoning, everyone thinks it is caused by the lead of brass itself, but all the doses that are left to talk about poisoning are hooligans. At present, the national standard for the lead content of faucets is that as long as the lead precipitation does not exceed 5 μg/L, it will not threaten human health. In fact, the standard H59 copper does not need to worry about this problem. Most of the faucets on the market that detect excessive lead precipitation are not standard brass, but are shodded with zinc alloy, or too much impurity is infiltrated, or roughly processed with recycled scrap copper. The faucets thus produced have quality problems.
There is another option for stainless steel faucets that wants to completely eliminate lead contact. Many brands are now developing stainless steel faucets because they can be completely lead-free, but they are not popular because of the complexity of the process and the lack of copper.
Shop TIPS:
Material selection: Brass: The most suitable faucet material has antibacterial effect. Among them, H59 copper is the most suitable, and the lead content is also qualified.
Stainless steel: It can be lead-free and is made of 304 food grade stainless steel for long-term contact with drinking water.
Contamination evaluation: The lead precipitation in the lead content test does not exceed 5 μg / L, which is qualified. Sensory evaluation: Brass: It can be identified by the method of estimating the weight. Brass is heavier and harder, and other alternative materials are lighter and softer. Stainless steel: Sensory contrast with sinks made from food grade stainless steel.

3. Is it inconvenient to use?
The faucet is not convenient to use, it really affects the quality of life. In the past, the faucet only supplied cold water. Every winter, washing dishes and washing vegetables became a tormenting work. Later, everyone chose the hot and cold mode. Now, we can have more choices and provide more life. Convenience.
