Stay away from lead-poisoned faucets How to remove lead from faucets

Posted on December 09 2022

Most of the faucets on the market are cast copper alloys, which contain 4%-8% lead and other elements. When lead encounters air, it will form a protective film with oxygen. After encountering water, this layer of protective film will fall off, causing lead to dissolve into the water, resulting in the precipitation of lead. Needless to say, the harm of lead to the human body, so how to remove lead from the faucet? The electroplating of the faucet contains lead. It is necessary to remove lead through certain methods in order to drink healthy water. Let’s take a look at the method of removing lead from the faucet.

Lead is a heavy metal well known to all of us. It is present in many malignant events that seriously endanger human health. It affects various organs such as nerves, hematopoiesis, digestion, urinary, reproduction, cardiovascular, endocrine, immunity, and bones. and hematopoietic system, and lead is more harmful to pregnant women and children, which may affect children's growth and intellectual development. Studies have shown that children's absorption rate of lead can be as high as 50%, so people need to pay special attention.

According to the survey, the problem of excessive lead in faucets that we have neglected for a long time is mainly related to the raw material of faucets - brass.

According to the survey, the problem of excessive lead in faucets that we have neglected for a long time is mainly related to the raw material of faucets - brass.

At present, the main material of domestic faucets is brass HPb59, and its lead content is required to be less than 1.9%. As the standard is, in order to reduce costs and improve the cutting performance of brass, some manufacturers use brass with a lead content of 3%-6 %, the temperature of faucet casting is generally 1053 degrees, and the melting point of lead is 327.5 degrees. In this way, lead segregates on the inner and outer surfaces during molding, and the lead content on the surface is 3-5 times higher than that in the interior. Using the lead removal process can remove the lead on the surface. The lead is taken out, but the water flowing in the faucet will destroy the surface of the lead, forming "corrosion", and the internal lead ions are exposed again, so that the precipitated lead content increases again.

Experts remind: choose genuine products from regular manufacturers carefully

Since the faucet is a small part of the bathroom, people have not paid much attention to the faucet, so how do we choose a safe and healthy faucet? Experts told us that since lead exists in metals, the appearance cannot be distinguished. The most direct way is to choose products from regular manufacturers and authoritative certification. When buying a water faucet, you can simply judge whether a faucet is good or bad by looking, weighing, and trying these three steps.

Look: Just observe, a good faucet should have a bright surface, no burrs, no scratches, and the lines on the edges are clear and smooth.

Holding: It means holding the faucet in your hand and feeling the weight of the faucet. A good faucet feels heavy and full of texture.

Test: It is to test the water. At present, places that sell professional faucets can test the water to see if there are bubbles in the water flowing out of the faucet? Isn't the water falling on the skin very gentle?

Ensure sufficient calcium, iron and zinc in the diet to maintain balance and effectively reduce lead absorption. Do not eat or eat less high-lead foods, such as preserved eggs, old-fashioned popcorn, and drink less canned beverages. Don't use colored glaze tableware, it is better to use white, smooth and transparent porcelain tableware.
  3. Do not stay or play in heavy traffic areas or industrial areas. Do not go for a walk on the side of the road (about 1 meter of the ground is the place with the highest concentration of lead). Children's clothes are washed separately, and parents play with their children after changing into home clothes.
  4. Have a good indoor environment: less smoking, less lead paint, less paint, less candles, etc.
