Lead-free faucet refers to the implementation of the US lead-free bill (senate bill 3874), in the category of pipeline products and fittings, whose water contact part has a lead content of not more than 0.25%. Lead is particularly harmful to the human body. If the tap is excessively contained, it will seriously affect the health of the body. So how do you pick a lead-free faucet? May wish to understand with Xiao Bian.
1, observe the appearance
In order to prevent the faucet from being oxidized, the faucet will be plated with a layer of nickel or chromium on its surface after being polished. Nickel or chromium has the function of resisting neutral hydrochloric acid and protects the faucet from corrosion for a long time. When you buy, look in a well-lit place. The surface of the faucet is free of oxidized spots, no air holes, no missing plating and blisters, and scorch marks. The uniform color without burrs and sand grains is a good product.
2, see the structure and material
When buying, it is best to look at the instructions to understand the internal structure of the faucet. Ceramic faucet faucets are recommended. They are made of high-durability ceramics. Even 60 pounds of water pressure can be switched freely without leakage. For washers, the recommended washers can withstand hot and cold water pressure without leakage.
3, choose a reliable brand
When buying taps of various materials, everyone must go to a regular shopping mall, and they must select well-known brands so that they can choose products with confidence. The quality of the faucet is related to the health of the family and must not be coveted. Regular faucet packing boxes should have brand identification, quality assurance and after-sales service instructions. Remind everyone to purchase must be cautious, in order to protect the lead content does not exceed the standard, try to choose stainless steel faucets.
4, on-site inspection
Finally, check the design rationality of the product. First move the switch a few times to see if the parts fit tightly and tightly. When turning the switch, feel soft. If the hand feels astringent or frivolous, it indicates that the assembly structure is unreasonable. When such a faucet is used, there may be insufficient water, or water leakage may occur when the water pressure increases.
