Are your faucets healthy?

In recent years, with the improvement of people’s living standards, the degree of concern for health is also increasing. Faucets are indispensable for residents’ homes and public places, and are the main components of kitchen and bathroom products. The performance of faucets is closely related to people’s lives, and directly affects the health of people’s lives and the social benefits of government energy conservation and emission reduction. Therefore, the heavy metal content of the faucet is one of the environmental health and safety indicators that people care about.

However, the excessive heavy metal content in faucets in real life is worrying. In recent years, major media have frequently exposed the secondary pollution of domestic tap water. Most of the mainstream faucet products on the market are made of copper alloy. In addition to the main copper and zinc elements, copper alloys also contain trace elements such as iron, aluminum, lead, tin, manganese, silicon, and nickel. If the lead content in the faucet is high, it is easy to precipitate lead during use. Therefore, the lead precipitation in the faucet mainly comes from the copper alloy material in contact with water. The main purpose of properly adding lead to copper is to improve the processing performance of copper. After the faucet is passed through, because the water contains enough oxygen, water and oxygen will cause electrochemical corrosion of copper, resulting in lead in copper alloy. Dissolution directly into the water, especially the “overnight water” in the faucet has higher levels of lead.
And the content of heavy metal element exceeds the normal value of blood lead content, will cause lead poisoning. Excessive blood lead will cause a series of abnormal performances in the nervous system, blood system, and digestive system of the body, affecting the normal functions of the human body.

How can we choose the faucet with lead precipitation content up to the standard?

Choose a heavier faucet

In the case of the same volume, the purer the copper, the heavier it is, so the material of the product can be easily judged by the weight when selecting. A good faucet is made of pure copper, and the valve body and handle of the faucet are all made of brass, which feels heavy in the hand. However, some small manufacturers use some miscellaneous copper and some other alloys, which have no weight.

The appearance should be fine

The left and right symmetry of the well-crafted faucet is very good, the surface is smooth and clean, the processing is fine, and it is easy to rotate without slipping. The inner wall of the faucet is a copper surface that does not rust or is not coated, so the flatness of the inner wall determines the smelting process of the product. Consumers can try to put their hands directly into the faucet hole, or take a look at the faucet handle, and judge the smelting process of the faucet through the smoothness of the inner wall.
