In home decoration, the choice of faucet is a link that many people ignore. The use of inferior faucets will cause secondary pollution of water quality. The originally qualified and clean tap water will contain lead and bacteria due to secondary pollution after flowing through inferior faucets. Carcinogens affect human health.
The main materials of the faucet are cast iron, plastic, zinc alloy, copper alloy, stainless steel, etc. The current faucets on the market are mainly made of copper alloy and stainless steel.

An important pollution of the faucet is excessive lead, and an important source of faucet pollution is the faucet of the kitchen sink.
Lead is a kind of toxic heavy which is extremely harmful to the human body.
After lead and its compounds enter the body, it will cause harm to many systems such as nerves, hematopoiesis, digestion, kidney, cardiovascular and endocrine. If the content is too high, it will cause lead poisoning.

The use of 304 food grade stainless steel faucet can be lead-free and can be in contact with drinking water for a long time. The disadvantage is that it does not have the antibacterial advantage of copper.

Copper ions have a certain bactericidal effect and prevent bacteria from producing antibodies, so the copper inner wall will not breed bacteria. This is incomparable to other materials, which is why many brands now choose copper materials to make faucets.

The brass in the copper alloy is an alloy of copper and zinc. It has good mechanical properties, wear resistance and corrosion resistance. At present, many brands use H59 copper to produce faucets, and few high-end brands use H62 copper to produce faucets. In addition to copper and zinc, brass also contains trace amounts of lead. H59 copper and H62 copper itself are safe. The leading products used in lead poisoning cases are not standard qualified brass, but use lead brass, yellow copper or even zinc alloy to be shoddy. Excessive lead is added to the copper water, or it is roughly processed from recycled waste copper. There is no cleaning, disinfection, testing and other links in the production process. The faucets produced in this way have quality problems.

So, how to choose a faucet to avoid excessive lead?
1. Stainless steel faucet can be used;

2. When choosing a copper faucet, you must choose a branded product, and you must see that the brass material used in the product must be qualified. For the product, you can also simply check whether the inner surface of the copper wall is smooth and clean, check whether there is any blisters, oxidation, whether the color of the copper is pure, and whether there is black hair or dark or peculiar smell.

3. Don’t choose copper faucets with too low price. Don’t choose Sanwu products on the market or products with obvious quality problems. For copper faucets that are significantly lower than the market price, the copper materials used will definitely have problems. Don’t be blinded by the low price.
