Detailed faucet containing lead truth to prevent pollution of pure water source

Faucets are typically made from copper, which is considered the best material for manufacturing today. Most faucets on the market, especially in Europe and America, are made of brass—a combination of copper and zinc. A small amount of lead is often added during production to improve the machinability of the brass. Without lead, the material may be difficult to cut and forge, and even if it’s made into a finished product, it could crack due to poor resistance to stress corrosion. Despite the presence of lead, copper faucets remain popular in developed countries. This is mainly because of copper's natural antibacterial properties. Historical records show that ancient Egyptians used copper for wound disinfection, treating eye infections, and purifying drinking water as early as 2500 BC. Modern research supports this—according to the U.S. Environmental Protection Agency (EPA), copper can kill over 99.9% of bacteria within an hour, making it the most effective antimicrobial surface material available. No other material, such as silver-coated surfaces or stainless steel, can match its effectiveness. Copper has proven to be highly effective against dangerous bacteria like MRSA, and these pathogens cannot develop immunity to it. The inner walls of copper faucets do not support bacterial growth, which is a major advantage over materials like stainless steel or plastic. With the development of low-lead copper (with less than 0.25% lead), copper remains the top choice for faucet manufacturing, offering both durability and health benefits. However, lead in brass faucets can still be a concern. In China, many faucets are made from HPb59 brass, which contains up to 1.9% lead. Some manufacturers use higher lead content (3–6%) to reduce costs and improve machinability. During casting, lead tends to separate and accumulate on the surface, where it can be exposed when the protective layer is worn away by water flow. This leads to increased lead leaching into the water supply. To address this, the U.S. introduced low-lead copper standards to minimize lead exposure. Lead is particularly harmful to children, whose bodies absorb it more easily than adults. Even small amounts of lead in the blood can cause serious developmental issues, including lower IQ and impaired cognitive function. Adults are more resistant, but lead exposure is still dangerous for everyone. When it comes to lead content, there are two main ways to measure it: the percentage of lead in the raw material and the amount of lead leached into water after testing. These are different metrics, so meeting one doesn’t guarantee the other. For example, the NSF61 standard in the U.S. sets strict limits on lead leaching, and China's JC/T1043 standard follows similar requirements. Testing involves immersing samples in water for extended periods and measuring lead levels. The latest Chinese standard, GB18145, requires a Q value of 5ug, ensuring safer products for consumers. To ensure safety, it's important for consumers to look for certified faucets from reputable testing institutions, such as the National Plumbing Hardware Testing Center or CQC Laboratory in China. Choosing the right material and following proper standards can help protect health and ensure long-term performance.
