Recently, all the copper faucets currently claimed in the sanitary ware market are lead brass, and even more, the use of yellow copper, greatly improving the lead content of the faucet. For this situation, many netizens have also spent corresponding solutions.
1, let go of the overnight water
How to choose a safe and qualified faucet has become a major problem for consumers. In this regard, the medical expert's suggestion is to "release the overnight water." Indeed, many people in the industry pointed out that "the current method to reduce the lead content of the faucet is to wash lead, but there is no way to eliminate it all. The faucet itself will accumulate a certain amount of water. After a long time, it will absorb heavy metals. Generally speaking, before using the faucet the next day, It is necessary to let the water accumulated in the faucet overnight and then use it."
2, commissioned third party testing
After the “lead lead exceeds the standard†incident, most brands have conducted source surveys and inspections on related products. According to Jiuzheng Building Materials Network, the national testing center needs 5 working days for testing. In addition to waiting for the merchants to publish the survey results, if consumers are not assured of the lead content of the home faucet, they can call the quality hotline 12365 of Shanghai Quality Supervision and Inspection Technology Research Institute for entrusted testing and consultation. At present, the single cost of this test is about 1,000 yuan.
3, look carefully before buying
Experts in the industry have suggested that when purchasing faucets, consumers should also carefully check the quality of faucet plating. Good plating is as bright as a mirror. Pressing on the surface with your hand will quickly disappear.
In addition, consumers are advised to ask the salesperson for the test report, brand identity and after-sales service card. If the test report determines that the product is qualified, it can be used with confidence.
